+# Excalidraw Automate How To
+
+Excalidraw Automate allows you to create Excalidraw drawings using the [Templater](https://github.com/SilentVoid13/Templater) plugin.
+
+With a little work, using Excalidraw Automate you can generate simple mindmaps, fill out SVG forms, create customized charts, etc. based on documents in your vault.
+
+You can access Excalidraw Automate via the ExcalidrawAutomate object. I recommend staring your Automate scripts with the following code.
+
+*Use CTRL+Shift+V to paste code into Obsidian!*
+```javascript
+const ea = ExcalidrawAutomate;
+ea.reset();
+```
+
+The first line creates a practical constant so you can avoid writing ExcalidrawAutomate 100x times.
+
+The second line resets ExcalidrawAutomate to defaults. This is important as you will not know which template you executed before, thus you won't know what state you left Excalidraw in.
+
+## Basic logic of using Excalidraw Automate
+1. Set the styling of the elements you want to draw
+2. Add elements. As you add elements, each new element is added one layer above the previous, thus in case of overlapping objects the later one will be on the top of the prior one.
+3. Call `await ea.create();` to instantiate the drawing
+
+You can change styling between adding different elements. My logic for separating element styling and creation is based on the assumption that you will probably set a stroke color, stroke style, stroke roughness, etc. and draw most of your elements using this. There would be no point in setting all these parameters each time you add an element.
+
+### Before we dive deeper, here are two a simple example scripts
+#### Create a new drawing with custom name, in a custom folder, using a template
+This simple script gives you significant additional flexibility over Excalidraw Plugin settings to name your drawings, place them into folders, and to apply templates.
+
+*Use CTRL+Shift+V to paste code into Obsidian!*
+```javascript
+<%*
+  const ea = ExcalidrawAutomate;
+  ea.reset();
+  await ea.create({
+    filename    : tp.date.now("HH.mm"), 
+    foldername  : tp.date.now("YYYY-MM-DD"),
+    templatePath: "Excalidraw/Template1.excalidraw",
+    onNewPane   : false
+  });
+%>
+```
+
+#### Create a simple drawing
+*Use CTRL+Shift+V to paste code into Obsidian!*
+```javascript
+<%*
+  const ea = ExcalidrawAutomate;
+  ea.reset();
+  ea.addRect(-150,-50,450,300);
+  ea.addText(-100,70,"Left to right");
+  ea.addArrow([[-100,100],[100,100]]);
+
+  ea.style.strokeColor = "red";
+  ea.addText(100,-30,"top to bottom",{width:200,textAligh:"center"});
+  ea.addArrow([[200,0],[200,200]]);
+  await ea.create();
+%>
+```
+The script will generate the following drawing:

+## Element Style
+As you will notice, some styles have setter functions. This is to help you navigate the allowed values for the property. You do not need to use the setter function however, you can use set the value directly as well.
+
+### strokeColor
+String. The color of the line. [CSS Legal Color Values](https://www.w3schools.com/cssref/css_colors_legal.asp)
+
+Allowed values are [HTML color names](https://www.w3schools.com/colors/colors_names.asp), hexadecimal RGB strings, or  e.g. `#FF0000` for red.

+"round" lines are curvey, "sharp" lines break at the turning point.
+
+`setStrokeSharpness()` accepts a number:
+- 0: "round"
+- any other number: "sharp"
+
+### fontFamily, setFontFamily()
+Number. Valid values are 1,2 and 3.
+

+
+![coordinates](https://user-images.githubusercontent.com/14358394/116825632-6569b980-ab90-11eb-827b-ada598e91e46.png)
+
+### addRect(), addDiamond(), addEllipse()
+```typescript
+addRect(topX:number, topY:number, width:number, height:number):string
+addDiamond(topX:number, topY:number, width:number, height:number):string
+addEllipse(topX:number, topY:number, width:number, height:number):string
+```
+Returns the `id` of the object. The `id` is required when connecting objects with lines. See later.
+
+### addText
+```typescript
+addText(topX:number, topY:number, text:string, formatting?:{width:number, height:number,textAlign: string, verticalAlign:string, box: boolean, boxPadding: number}):string
+```
+
+Adds text to the drawing. 
+
+Formatting parameters are optional:
+- If `width` and `height` are not specified, the function will calculate the width and height based on the fontFamily, the fontSize and the text provided.
+- In case you want to position a text in the center compared to other elements on the drawing, you can provide a fixed height and width, and you can also specify `textAlign` and `verticalAlign` as described above. e.g.: `{width:500, textAlign:"center"}`
+- If you want to add a box around the text, set `{box:true}`
+
+Returns the `id` of the object. The `id` is required when connecting objects with lines. See later. If `{box:true}` then returns the id of the enclosing box.
+
+### addLine()
+```typescript
+addLine(points: [[x:number,y:number]]):void
+```
+Adds a line following the points provided. Must include at least two points `points.length >= 2`. If more than 2 points are provided the interim points will be added as breakpoints. The line will break with angles if `strokeSharpness` is set to "sharp" and will be curvey if it is set to "round".
+
+### addArrow()
+```typescript
+addArrow(points: [[x:number,y:number]],formatting?:{startArrowHead:string,endArrowHead:string,startObjectId:string,endObjectId:string}):void
+```
+
+Adds an arrow following the points provided. Must include at least two points `points.length >= 2`. If more than 2 points are provided the interim points will be added as breakpoints. The line will break with angles if element `style.strokeSharpness` is set to "sharp" and will be curvey if it is set to "round".
+
+`startArrowHead` and `endArrowHead` specify the type of arrow head to use, as described above. Valid values are "none", "arrow", "dot", and "bar". e.g. `{startArrowHead: "dot", endArrowHead: "arrow"}`
+
+`startObjectId` and `endObjectId` are the object id's of connected objects. I recommend using `connectObjects` instead calling addArrow() for the purpose of connecting objects.
+
+### connectObjects()
+```typescript
+declare type ConnectionPoint = "top"|"bottom"|"left"|"right";
+connectObjects(objectA: string, connectionA: ConnectionPoint, objectB: string, connectionB: ConnectionPoint, formatting?:{numberOfPoints: number,startArrowHead:string,endArrowHead:string, padding: number}):void
+```
+Connects two objects with an arrow.
+
+`objectA` and `objectB` are strings. These are the ids of the objects to connect. These IDs are returned by addRect(), addDiamond(), addEllipse() and addText() when creating those objects.
+
+`connectionA` and `connectionB` specify where to connect on the object. Valid values are: "top", "bottom", "left", and "right".
+
+`numberOfPoints` set the number of interim break points for the line. Default value is zero, meaning there will be no breakpoint in between the start and the end points of the arrow. When moving objects on the drawing, these breakpoints will influence how the line is rerouted by Excalidraw.
+
+`startArrowHead` and `endArrowHead` work as described for `addArrow()` above.
+
+### addToGroup()
+```typescript
+addToGroup(objectIds:[]):void
+```
+Groups objects listed in `objectIds`.
+
+## Utility functions
+### clear()
+`clear()` will clear objects from cache, but will retain element style settings.
+
+### reset()
+`reset()` will first call `clear()` and then reset element style to defaults.
+
+### toClipboard()
+```typescript
+async toClipboard(templatePath?:string)
+```
+Places the generated drawing to the clipboard. Useful when you don't want to create a new drawing, but want to paste additional items onto an exising drawing.
+
+### create()
+```typescript
+async create(params?:{filename: string, foldername:string, templatePath:string, onNewPane: boolean})
+```
+Creates the drawing and opens it.
+
+`filename` is the filename without extension of the drawing to be created. If `null`, then Excalidraw will generate a filename.
+
+`foldername` is the folder where the file should be created. If `null` then the default folder for new drawings will be used according to Excalidraw settings.
+
+`templatePath` the filename including full path and extension for a template file to use. This template file will be added as the base layer, all additional objects added via ExcalidrawAutomate will appear on top of elements in the template. If `null` then no template will be used, i.e. an empty white drawing will be the base for adding objects.
+
+`onNewPane` defines where the new drawing should be created. `false` will open the drawing on the current active leaf. `true` will open the drawing by vertically splitting the current leaf.
+
+Example:
+```javascript
+create({filename:"my drawing", foldername:"myfolder/subfolder/", templatePath: "Excalidraw/template.excalidraw", onNewPane: true});
+```
+### createSVG()
+```typescript
+async createSVG(templatePath?:string)
+```
+Returns an HTML SVGSVGElement containing the generated drawing.
+
+### createPNG()
+```typescript
+async createPNG(templatePath?:string)
+```
+Returns a blob containing a PNG image of the generated drawing.
+
+## Examples
+### Insert new drawing into currently edited document
+This template will prompt you for the title of the drawing. It will create a new drawing with the provided title, and in the folder of the document you were editing. It will then transclude the new drawing at the cursor location and open the new drawing in a new workspace leaf by splitting the current leaf.
+
+*Use CTRL+Shift+V to paste code into Obsidian!*
+```javascript
+<%*
+  const defaultTitle = tp.date.now("HHmm")+' '+tp.file.title;
+  const title = await tp.system.prompt("Title of the drawing?", defaultTitle);
+  const folder = tp.file.folder(true);
+  const transcludePath = (folder== '/' ? '' : folder + '/') + title + '.excalidraw';
+  tR = String.fromCharCode(96,96,96)+'excalidraw\n[['+transcludePath+']]\n'+String.fromCharCode(96,96,96);
+  const ea = ExcalidrawAutomate;
+  ea.reset();
+  ea.setTheme(1); //set Theme to dark
+  await ea.create({
+    filename : title,
+    foldername : folder,
+    //templatePath: 'Excalidraw/Template.excalidraw', //uncomment if you want to use a template
+    onNewPane : true
+  });
+%>
+```
+
+### Connect objects
+*Use CTRL+Shift+V to paste code into Obsidian!*
+```javascript
+<%*
+  const ea = ExcalidrawAutomate;
+  ea.reset();
+  ea.addText(-130,-100,"Connecting two objects");
+  const a = ea.addRect(-100,-100,100,100);
+  const b = ea.addEllipse(200,200,100,100);
+  ea.connectObjects(a,"bottom",b,"left",{numberOfPoints: 2}); //see how the line breaks differently when moving objects around
+  ea.style.strokeColor = "red";
+  ea.connectObjects(a,"right",b,"top",1);
+  await ea.create();
+%>
+```
+### Using a template
+This example is similar to the first one, but rotated 90°, and using a template, plus specifying a filename and folder to save the drawing, and opening the new drawing in a new pane.
+
+*Use CTRL+Shift+V to paste code into Obsidian!*
+```javascript
+<%*
+  const ea = ExcalidrawAutomate;
+  ea.reset();
+  ea.style.angle = Math.PI/2; 
+  ea.style.strokeWidth = 3.5;
+  ea.addRect(-150,-50,450,300);
+  ea.addText(-100,70,"Left to right");
+  ea.addArrow([[-100,100],[100,100]]);
+
+  ea.style.strokeColor = "red";
+  await ea.addText(100,-30,"top to bottom",{width:200,textAlign:"center"});
+  ea.addArrow([[200,0],[200,200]]);
+  await ea.create({filename:"My Drawing",foldername:"myfolder/fordemo/",templatePath:"Excalidraw/Template2.excalidraw",onNewPane:true});
+%>
+```
+
+### Generating a simple mindmap from a text outline
+This is a slightly more elaborate example. This will generate an a mindmap from a tabulated outline.

+# Obsidian Excalidraw Plugin
 The Obsidian-Excalidraw plugin integrates [Excalidraw](https://excalidraw.com/), a feature rich sketching tool, into Obsidian. You can store and edit Excalidraw files in your vault and you can transclude drawings into your documents. For a showcase of Excalidraw features, please read my blog post [here](https://www.zsolt.blog/2021/03/showcasing-excalidraw.html).
 
-![image](https://user-images.githubusercontent.com/14358394/115391516-d9df4880-a1df-11eb-95a9-cad850cdf9fc.png)
+**See details of the 1.0.6, 1.0.7 and 1.0.8 releases including a short video, further below**
 
-### Key features
-- The plugin adds 3 commands to the command palette. 1) To create a new drawing. 2) To find and edit existing drawings in your vault, and 3) to transclude a drawing into a document.
-- You can also use the file explorer in your vault to open Excalidraw files.
-- You can set up a default folder for saving new drawings in Settings. 
-- You can set up a Template by creating a drawing, customizing it the way you like it, and specifying the file as the template in settings.
-- The plugin saves drawings to your vault as a file with the .excalidraw file-extension.
-- You can set the size of embedded image using the [[image.excalidraw|100]] or [[image.excalidraw|100x100]] format.
+![image](https://user-images.githubusercontent.com/14358394/115983515-d06c2c80-a5a1-11eb-8d12-c7df91d18107.png)
 
-### How to?
-- Add a library: Click [browse libraries](https://libraries.excalidraw.com/?target=_excalidraw&sort=default) in Excalidraw. Download the preferred library and close browser tab. Click Load library in Excalidraw-Obsidian to load your locally saved library.
+## Key features
+- The plugin adds the following actions to the **command palette**:
+  - To create a new drawing
+  - To find and edit existing drawings in your vault, 
+  - To embed (transclude) a drawing into a document, and
+  - To export a drawing as PNG or SVG.
+- You can also use the **file explorer** in your vault to open Excalidraw files. 
+- Use the **ribbon button** to create a new drawing, do CTRL+Click to open on a new page.
+- Open settings to set up a **default folder** for new drawings. 
+- Set up a **Template** by creating a drawing, customizing it the way you like it, and specifying the file as the template in settings.
+- The plugin saves drawings to your vault as a file with the *.excalidraw* file extension.
+- You can customize the **size and position of the embedded image** using the `[[image.excalidraw|100]]`, `[[image.excalidraw|100x100]]`, `[[image.excalidraw|100|left]]`, `[[image.excalidraw|right-wrap]]`, formatting options. `[[<filename.excalidraw>|<width>x<height>|<alignment>]]`. You can add your custom alignment via css. Any text that appears in `<alignment>` will be added as style to the SVG element and the wrapper DIV element. Check below and styles.css for more insight.
+- You can setup Excalidraw to **automatically export SVG and/or PNG** files for your drawings, and to keep those in sync with your drawing.
+- Includes full [Templater](https://silentvoid13.github.io/Templater/) and [Dataview](https://blacksmithgu.github.io/obsidian-dataview/docs/api/intro/) support through ExcalidrawAutomate. Read detailed help + examples: [here](https://zsviczian.github.io/obsidian-excalidraw-plugin/)
 
-### Known issues
-- When inserting images from the library, sometimes these images appear out of view. You’ll need to select “scroll to view” at the bottom of the screen. This is a bug in Excalidraw. The Excalidraw development team has successfully reproduced the bug and promised to resolve it in the next update of Excalidraw.
-- On iPad: As you draw left to right it opens left sidebar. Draw right to left, opens right sidebar. Draw down, opens commands palette. So seems open is emulating the gestures, even when drawing towards the center. I have raised the problem with the Obsidian.md team, and Licat promised to resolve this issue in the next Obsidian release.

+## 1.0.6 and 1.0.7 update
+[![1.0.6 Update](https://user-images.githubusercontent.com/14358394/116312909-58725200-a7ad-11eb-89b9-c67cb48ffebb.jpg)](https://youtu.be/ipZPbcP2B0M)
+
+### SVG styling when embedding using a code block
+- 1.0.7 adds further flexibility to styling
+- new formatting option for the code block embedding
+- Valid values: `left`, `right`, `left-wrap`, `right-wrap`... but anything after the last `|` character will be added to the class of the SVG element and the wrapper DIV element.
+Here is the corresponding CSS:
+```
+svg.excalidraw-svg-right-wrap {
+  float: right;
+  margin: 0px 0px 20px 20px;
+}
+
+svg.excalidraw-svg-left-wrap {
+  float: left;
+  margin: 0px 35px 20px 0px;
+}
+
+div.excalidraw-svg-right {
+  text-align: right;
+}
+
+div.excalidraw-svg-left {
+  text-align: left;
+}
+```
+## 1.0.8 + 1.0.9 (minor fixes) update 
+[![Obsidian-Excalidraw 1.0.8 update](https://user-images.githubusercontent.com/14358394/117492534-029e6680-af72-11eb-90a3-086e67e70c1c.jpg)](https://youtu.be/AtEhmHJjnxM)
+
+### QoL improvements
+- Adds context menu to File Explorer to create new drawings
+- Adds a new command to the palette: “Transclude (embed) the most recently edited Excalidraw drawing”
+- Automatically update file-links in transclusions when you rename or move your drawing
+- Saves drawing and updates all active pre-views when drawing loses focus
+- File is closed and removed when you select “Delete file” from more options
+- Saves drawing when exiting Obsidian
+- Fixes pen positioning bug with sliding panes after panes scroll
+
+### ExcalidrawAutomte full Templater and DataviewJS support
+You now have ultimate flexibility over your Excalidraw templates using Templater and Dataview.
+- Detailed documentation available [here](https://zsviczian.github.io/obsidian-excalidraw-plugin/)
+- I created few examples from the simple to the more complex
+	- Simple use-case: Creating a drawing using a custom template and following a file and folder naming convention of your choice.
+	- Complex use-case: Create a mindmap from a tabulated outline.
+  ![Drawing 2021-05-05 20 52 34](https://user-images.githubusercontent.com/14358394/117194124-00a69d00-ade4-11eb-8b75-5e18a9cbc3cd.png)
+  
+## Known issues
+- On mobile (iOS and Android): As you draw left to right it opens left sidebar. Draw right to left, opens right sidebar. Draw down, opens commands palette. So seems open is emulating the gestures, even when drawing towards the center. Obsidian mobile 0.18 has resolved this issue.
+- I have seen two cases when adding a stencil library did not work. In both cases, the end solution was a reinstall of Obsidian. The root cause is not clear, but maybe because of  the incremental updates of Obsidian from an early version.
+- Mobile support
+  - Positioning of the pen gets misaligned after you open the command palette.
+  - Your drawing will not be saved when you terminate the mobile app by closing the Obsidian task.
+- Sync does not support .excalidraw files. This issue will be addressed in a later release of Obsidian sync. Until then, here are two hacks you can play with: 
+  - You have the option to use OneDrive, Google Drive, iCloud, DropBox, etc. to sync your vault between devices.
+  - You can also use Obsidian Sync in conjunction with "Obsidian Git" (find it in community plugins). Be sure to set up git to ignore all files except for .excalidraw by adding the following to `.gitignore`. Obsidian Git does not work on mobile, but on Android you can use an app like MGIT to sync your `.excalidraw` files from/to the git repository.
+  ```
+  #ignore all kind of files
+  *.*
+  #except excalidraw files
+  !*.excalidraw
+  ```
+## Tips and tricks
+- If you want to sketch in fullscreen, I recommend installing the [Fullscreen Focus Mode](https://github.com/razumihin/obsidian-fullscreen-plugin) plugin.

+# [◀ Excalidraw Automate How To](../readme.md)
+## Introduction to the API
+You can access Excalidraw Automate via the ExcalidrawAutomate object. I recommend staring your Automate scripts with the following code.
+
+*Use CTRL+Shift+V to paste code into Obsidian!*
+```javascript
+const ea = ExcalidrawAutomate;
+ea.reset();
+```
+
+The first line creates a practical constant so you can avoid writing ExcalidrawAutomate 100x times.
+
+The second line resets ExcalidrawAutomate to defaults. This is important as you will not know which template you executed before, thus you won't know what state you left Excalidraw in.
+
+### Basic logic of using Excalidraw Automate
+1. Set the styling of the elements you want to draw
+2. Add elements. As you add elements, each new element is added one layer above the previous, thus in case of overlapping objects the later one will be on the top of the prior one.
+3. Call `await ea.create();` to instantiate the drawing
+
+You can change styling between adding different elements. My logic for separating element styling and creation is based on the assumption that you will probably set a stroke color, stroke style, stroke roughness, etc. and draw most of your elements using this. There would be no point in setting all these parameters each time you add an element.
+
+### Before we dive deeper, here are two a simple example scripts
+#### Create a new drawing with custom name, in a custom folder, using a template
+This simple script gives you significant additional flexibility over Excalidraw Plugin settings to name your drawings, place them into folders, and to apply templates.
+
+*Use CTRL+Shift+V to paste code into Obsidian!*
+```javascript
+<%*
+  const ea = ExcalidrawAutomate;
+  ea.reset();
+  await ea.create({
+    filename    : tp.date.now("HH.mm"), 
+    foldername  : tp.date.now("YYYY-MM-DD"),
+    templatePath: "Excalidraw/Template1.excalidraw",
+    onNewPane   : false
+  });
+%>
+```
+
+#### Create a simple drawing
+*Use CTRL+Shift+V to paste code into Obsidian!*
+```javascript
+<%*
+  const ea = ExcalidrawAutomate;
+  ea.reset();
+  ea.addRect(-150,-50,450,300);
+  ea.addText(-100,70,"Left to right");
+  ea.addArrow([[-100,100],[100,100]]);
+
+  ea.style.strokeColor = "red";
+  ea.addText(100,-30,"top to bottom",{width:200,textAligh:"center"});
+  ea.addArrow([[200,0],[200,200]]);
+  await ea.create();
+%>
+```
+The script will generate the following drawing:
+
+![FristDemo](https://user-images.githubusercontent.com/14358394/116825643-6e5a8b00-ab90-11eb-9e3a-37c524620d0d.png)

+## Adding objects
+These functions will add objects to your drawing. The canvas is infinite, and it accepts negative and positive X and Y values. X values increase left to right, Y values increase top to bottom.
+
+![coordinates](https://user-images.githubusercontent.com/14358394/116825632-6569b980-ab90-11eb-827b-ada598e91e46.png)
+
+### addRect(), addDiamond(), addEllipse()
+```typescript
+addRect(topX:number, topY:number, width:number, height:number):string
+addDiamond(topX:number, topY:number, width:number, height:number):string
+addEllipse(topX:number, topY:number, width:number, height:number):string
+```
+Returns the `id` of the object. The `id` is required when connecting objects with lines. See later.
+
+### addText()
+```typescript
+addText(topX:number, topY:number, text:string, formatting?:{width:number, height:number,textAlign: string, verticalAlign:string, box: boolean, boxPadding: number}):string
+```
+
+Adds text to the drawing. 
+
+Formatting parameters are optional:
+- If `width` and `height` are not specified, the function will calculate the width and height based on the fontFamily, the fontSize and the text provided.
+- In case you want to position a text in the center compared to other elements on the drawing, you can provide a fixed height and width, and you can also specify `textAlign` and `verticalAlign` as described above. e.g.: `{width:500, textAlign:"center"}`
+- If you want to add a box around the text, set `{box:true}`
+
+Returns the `id` of the object. The `id` is required when connecting objects with lines. See later. If `{box:true}` then returns the id of the enclosing box.
+
+### addLine()
+```typescript
+addLine(points: [[x:number,y:number]]):void
+```
+Adds a line following the points provided. Must include at least two points `points.length >= 2`. If more than 2 points are provided the interim points will be added as breakpoints. The line will break with angles if `strokeSharpness` is set to "sharp" and will be curvey if it is set to "round".
+
+### addArrow()
+```typescript
+addArrow(points: [[x:number,y:number]],formatting?:{startArrowHead:string,endArrowHead:string,startObjectId:string,endObjectId:string}):void
+```
+
+Adds an arrow following the points provided. Must include at least two points `points.length >= 2`. If more than 2 points are provided the interim points will be added as breakpoints. The line will break with angles if element `style.strokeSharpness` is set to "sharp" and will be curvey if it is set to "round".
+
+`startArrowHead` and `endArrowHead` specify the type of arrow head to use, as described above. Valid values are "none", "arrow", "dot", and "bar". e.g. `{startArrowHead: "dot", endArrowHead: "arrow"}`
+
+`startObjectId` and `endObjectId` are the object id's of connected objects. I recommend using `connectObjects` instead calling addArrow() for the purpose of connecting objects.
+
+### connectObjects()
+```typescript
+declare type ConnectionPoint = "top"|"bottom"|"left"|"right";
+connectObjects(objectA: string, connectionA: ConnectionPoint, objectB: string, connectionB: ConnectionPoint, formatting?:{numberOfPoints: number,startArrowHead:string,endArrowHead:string, padding: number}):void
+```
+Connects two objects with an arrow.
+
+`objectA` and `objectB` are strings. These are the ids of the objects to connect. These IDs are returned by addRect(), addDiamond(), addEllipse() and addText() when creating those objects.
+
+`connectionA` and `connectionB` specify where to connect on the object. Valid values are: "top", "bottom", "left", and "right".
+
+`numberOfPoints` set the number of interim break points for the line. Default value is zero, meaning there will be no breakpoint in between the start and the end points of the arrow. When moving objects on the drawing, these breakpoints will influence how the line is rerouted by Excalidraw.
+
+`startArrowHead` and `endArrowHead` work as described for `addArrow()` above.
+
+### addToGroup()
+```typescript
+addToGroup(objectIds:[]):void
+```
+Groups objects listed in `objectIds`.

+## Utility functions
+### clear()
+`clear()` will clear objects from cache, but will retain element style settings.
+
+### reset()
+`reset()` will first call `clear()` and then reset element style to defaults.
+
+### toClipboard()
+```typescript
+async toClipboard(templatePath?:string)
+```
+Places the generated drawing to the clipboard. Useful when you don't want to create a new drawing, but want to paste additional items onto an exising drawing.
+
+### create()
+```typescript
+async create(params?:{filename: string, foldername:string, templatePath:string, onNewPane: boolean})
+```
+Creates the drawing and opens it.
+
+`filename` is the filename without extension of the drawing to be created. If `null`, then Excalidraw will generate a filename.
+
+`foldername` is the folder where the file should be created. If `null` then the default folder for new drawings will be used according to Excalidraw settings.
+
+`templatePath` the filename including full path and extension for a template file to use. This template file will be added as the base layer, all additional objects added via ExcalidrawAutomate will appear on top of elements in the template. If `null` then no template will be used, i.e. an empty white drawing will be the base for adding objects.
+
+`onNewPane` defines where the new drawing should be created. `false` will open the drawing on the current active leaf. `true` will open the drawing by vertically splitting the current leaf.
+
+Example:
+```javascript
+create({filename:"my drawing", foldername:"myfolder/subfolder/", templatePath: "Excalidraw/template.excalidraw", onNewPane: true});
+```
+### createSVG()
+```typescript
+async createSVG(templatePath?:string)
+```
+Returns an HTML SVGSVGElement containing the generated drawing.
+
+### createPNG()
+```typescript
+async createPNG(templatePath?:string)
+```
+Returns a blob containing a PNG image of the generated drawing.

+# Excalidraw Automate How To
+
+Excalidraw Automate allows you to create Excalidraw drawings using the [Templater](https://silentvoid13.github.io/Templater/docs/) plugin, and to generate embedded SVG and PNG images using [DataviewJS](https://blacksmithgu.github.io/obsidian-dataview/docs/api/intro/)
+
+With a little work, using Excalidraw Automate you can generate simple mindmaps, build a faimly tree, fill out SVG forms, create customized charts, etc. based on documents in your vault.
