Krita: Animated Vector Brush

Summary

  • Project Name: Animated Vector Brush for Krita
  • Proposal: Google Docs Proposal
  • Abstract: This projects aims to implement an Animated Vector Brush for Krita, which uses SVG as a source file for the brush tips. The purpose of an animated brush is to change the brush tips automatically with every dab on the canvas. This allows for a quick way to paint different images, create random and fun designs, and explore new ways to paint that are not easy in physical world. In the other hand, using SVG as a source makes it easy to share the brush tips as they are saved as plain text, as opposed to raster image brushes.

Project Goals

  • Write documentation for end users as per the Krita Contribution Guide.
  • Define the structure of the SVG file containing the source tips for the Animated Vector Brush
  • Load AVB
  • Parse SVG
  • Render SVG as images
  • Write a helper parasite class
  • Change brush tip with every dab
  • Save AVB

Implementations Status

Write documentation

  • Goal: The documentation should be written for end users as per the Krita Contribution Guide, it should also be sufficient for the users to understand and use the brush.
  • Status: The documentation is mostly done, it is only necessary to add the proper screenshots and update in case of changes.
  • TODO: Add screenshots.

Commits and Differentials

Load AVB

  • Goal: The Animated Vector Brush file should be loaded and call the proper Class, in this case kis_vectoranimated_brush
  • Status: The implementation is done, the loading of the AVB by the user is using the +import tab.

Commits and Differentials

Parse SVG

  • Goal: The SVG should be parsed and transformed to KoShape as necessary, so Krita can use them to set brushTipImage, paint dabs or change the size of the brush tip.
  • Status: Done.
  • Related blog post: Basic functionality almost ready

Commits and Differentials

Render brush tips as images.

  • Goal: The KoShapes should be transformed to QImage as necessary, so Krita can use them to set brushTipImage, paint dabs or change the size of the brush tip.
  • Status: Done.

Commits and Differentials


Write a helper parasite class

  • Goal: Write a class that will aid the ~kis_vectoranimatedbrush~ class, holding the values of the Index and related data.
  • Status: In Progress. Although the majority of the class works now, there is a need for comments and cleaning.

Commits and Differentials


Change brush tip with every dab.

  • Goal: Change the brushTipimage with every dab
  • Status: In Progress. As of right now the images are being changed with every dab but it could be done in a faster way, not using ~prepareForSeqNo~ or limiting the amount of times it runs.
  • Related blog post: To be written

Commits and Differentials

    • Save as AVB.
