 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, you can embed drawings into your documents, and you can link to documents and other drawings to/and from Excalidraw. For a showcase of Excalidraw features, please read my blog post [here](https://www.zsolt.blog/2021/03/showcasing-excalidraw.html) and/or watch the videos below.
 
+Please upgrade to Obsidian v0.12.19 or higher to get the latest release.

-# Important notice to the 1.2.0 update
-
-This version comes with tons of new features and possibilities. 
-
-Drawings you've created with version 1.1.x need to be converted to take advantage of the new features. If you want, you can also continue to use your exisiting drawings in compatibility mode (e.g. if you use Logseq and Obsidian in parallel). During conversion your existing `*.excalidraw` files will be replaced with new `*.excalidraw.md` files.
-
-## Conversion and compatibility
-To convert files you have the following options:
-- Click `CONVERT FILES` in the migration dialog when installing 1.2.0
-- In the Command Palette select `Excalidraw: Convert *.excalidraw files to *.excalidraw.md files` to convert all `*.excalidraw` files to `*.excalidraw.md` files. 
-- To convert files individually: 
-  - Right click an `*.excalidraw` file in File Explorer and select one of the following options:
-    - `*.excalidraw => *.excalidraw.md`
-    - `*.excalidraw => *.md (Logseq compatibility)`: This option will retain the original *.excalidraw file next to the new Obsidian format. Make sure you also enable additional `Compatibility features` in `Settings` for a full solution.
-  - Open a legacy `*.excalidraw` file and select `Convert to new format` from the `Options Menu` in the Excalidraw view.

-  - If portability is important to you: Auto-export SVG and/or PNG files including keep-in-sync feature so you can embed svg/png into your documents instead of embedding excalidraw files.

You can add your custom alignment via css. Any text that appears in `<alignment>` will be added to the rendered SVG element style and to the wrapper DIV element. Check below and styles.css for more insight.

   - Transclusions are supported 
     - `![[myfile#^blockref]]` will convert in the drawing into the transcluded text of the block
     - `![[myfile#section]]` also works, this will transclude the section
     - you can also specify word wrapping for transcluded text by adding the max character count in curly brackets right after the transclusion e.g. `![[myfile#^blockref]]{40}` will wrap text at 40 characters.

+- Embed complete markdown files into your drawings
+  - Drag from the desired file from the Obsidian file explorer and hold down CTRL/CMD while dropping the file onto the canvas.
+  - Use the command palette action: `Insert markdown file from vault`
+  - Use custom woff, woff2 or TTF font to display the document, you can set the default font to use under Excalidraw Settings.
+  - You can set a custom css for rendering the snapshot image of your markdown document. Only operating system standard fonts are supported as the font-family ([Win10](https://docs.microsoft.com/en-us/typography/fonts/windows_10_font_list), [Mac & iOS](https://developer.apple.com/fonts/system-fonts/)), plus you can set one additional custom font using the setting explained above. (for a demonstration watch this [video](https://youtu.be/K6qZkTz8GHs) and check out this [sample css](https://github.com/zsviczian/obsidian-excalidraw-plugin/discussions/281)).
+    - To help with styling you can observe the SVG snapshot of the markdown document created by Excalidraw. Open Obsidian Developer Console (CTRL+Shift+i) and execute the following command: `ExcalidrawAutomate.mostRecentMarkdownSVG`
+  - You can control appearance of the embedded markdown file on a file by file bases by adding the following front matter keys to your markdown document:
+    - `excalidraw-font: Virgil|Cascadia|font_file_name.extension`
+    - `excalidraw-font-color: css-color-name|#HEXcolor|any-other-html-standard-format`, you can find css color names [here](https://www.w3schools.com/colors/colors_names.asp).

I also have a [YouTube ExcalidrawAutomate Playlist](https://www.youtube.com/playlist?list=PL6mqgtMZ4NP1IR4nXxSlMA4PA5E-qpyHZ) with lots of examples.
 - REQUIRES AN OBSIDIAN SYNC SUBSCRIPTION: Full drawing file history and synchronization between devices
 - Multilanguage support: if you'd like to help out by translating the plugin, please get in contact with me.
 
 # Known issues
 - Mobile support
-  - Positioning of the pen gets misaligned after you open the command palette.
   - Partially mitigated in 1.0.10 by the introduction of autosave: Your drawing will not be saved when you terminate the mobile app by closing the Obsidian task. 
+- Text elements "jumps off screen" when editing, if drawing is zoomed in and text element does not fit the visible screen area. I am working on a resolution.
 
 # 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.
-- [Ozan's Image in Editor Plugin](https://github.com/ozntel/oz-image-in-editor-obsidian). In a nice collaboration with Ozan, his Image-in-Editor plugin now supports Excalidraw. I recommend installing his plugin to display drawings also in Edit mode. Note that Ozan's plugin will only display Excalidraw drawings if the link ends with `.md` or `.excalidraw`. i.e. the following drawing will show in Edit Mode `![[My Drawing.md]]`, but wiki links such as `[[My Drawing]]` will not.
