What is an Animated Vector Brush
If you ever used Krita or Gimp, you might have heard of the GIH brushes (Gimp Image Hose). This type of brushes allow for multiple images to be stored as a single brush. Every stroke you paint will give you a different image, giving the feeling they are "animated".
Problems with GIH
The problem with GIH brushes is that they are saved as raster images, so if you are an artists you might face one or more of the following problems:
- Scaling is difficult: this is related to the raster image format, if you did not save in high quality, you can't enlarge the tips much, and if you use high quality your file can be several MB.
- The file size is big: because raster images can be several MB of size, specially if you want high quality brushes with multiple tips.
- Hard to distribute: Of course, because of the size of the brushes, distributing a pack of this brushes can take more than a few hundred MB.
- No good git support: Raster images don't get along well with git.
Animated Vector Brush
Vectors, unlike raster images, are not composed of values of pixels, but rather they are a mathematical description of a shape, and as a formula they can be resized to any shape you want.
The best example of vector image format is of course Scalable Vector Graphics or SVG, this format is just an XML text file (perfect for git!), and you can even write SVG by hand.
SVG has a
<symbol> element, which is a container element to define template objects, good for creating a library of shapes to be used in vector graphics design, or, in this case, to be used as a format to store brush tips which Krita will understand.
It is worth noting that my project does not intend for this SVG brushes to be used as vectors, they will be rendered to raster images to paint in a regular Krita layer.

I am not an artists, but if you are, or you just enjoy using Krita, I would greatly appreciate your feedback because I want to make this tool as useful as possible for all the Krita community.
