Anki-StylusDraw

Initially based on the Anki-TouchScreen addon, updated ui and added pressure pen/stylus capabilities, perfect freehand(line smoothing) and calligrapher functionality.

Website to test the drawing functionality: https://rytisgit.github.io/Anki-StylusDraw/

Changes

• Added background color selection
• Added follow screen mode(menu option) and small canvas mode(alt + b) to increase drawing speed on very big cards
• Added toolbar location configuration and other small fixes.

• Added Perfect Freehand mode(https://github.com/steveruizok/perfect-freehand)
• Added Calligrapher mode(https://github.com/atomanyih/Calligrapher)
• Added pressure sensitivity
• Increased drawing speed

Hardware

Tested to work with a Huion H1161, Windows Pen enabled.

For best experience:

• don't use software rendering(enable hardware acceleration)

• turn on use pen as a mouse with Windows Pen

• if drawing is slow on big cards turn on follow mode or small canvas

Old Description

Implements same drawing/writing mechanism as in AnkiDroid. Your writing is NOT intended to remain on the cards after review - same as in AnkiDroid.

Use the menu View → TouchScreen to activate/change settings.

Use Ctrl + R to toggle the touchscreen.

Use icons which will show up in the top right corner of the review screen to temporarily hide/clean the board. Enjoy!

Warning: the version for Anki 2.0 has limited functionality, and may sometimes not work as expected; since the release of Anki 2.1, the old version is not supported.

Changelog:

• 0.2.6 - make "undo" action available under Alt + Z
• 0.2.4 - add support for enhanced image occlusion, add a fix for "a double click bug" by LaucianK
• 0.2.3 - bug fix release, improvements to undo button, styling and performance
• 0.2.1 - minor fix for the buttons/canvas positioning
