One thing I used to do a lot in photoshop was to make custom shapes that I’d use later in painting, which for some more graphical styles makes it a lot faster. They were really easy to make, all I needed was a selection and to choose an option from a menu and save it, then I could drag them out and have them appear rasterized and ready to paint into. So for instance if I paint some black silhouettes of trees, I can then select them and save the shape, and quickly place a bunch of them in an image later, not having to worry about their resolution as with brushes.
I’ve been wanting to recreate this in krita, as it does have some part of this ability in that it has a vector library docker that lets me drag them out quickly, and I can convert them into raster without much fuss even if it’s not automatic.
However, I can’t figure out how to make a new shape. I am a bit confused by the documentation for libraries, as it says “Currently, you cannot make symbol libraries with Krita yet, but you can make them by hand, as well as use Inkscape to make them.” and I do not know what making them by hand would imply, as opposed to using another program. Does this mean that while it could not make a ‘library’ itself, I could still create shapes for one in krita? Or would the whole process need to be external?
