Alchemy Pull Shapes for Krita

Sat May 04, 2013 5:29 am
I've been missing Alchemy Pull Shapes inside Krita so I set up to try to mimic Pull Shapes using Gimp .gih brush formats.

All shapes come from Alchemy default shapes and David Revoy's Shapes, there is one new made for workflow testing purposes. Because it was finished I found no reason not to include it.

I made each image 250x250 pixels to allow bigger forms with good sharpening, but I'm not sure it that's the best way to do it. I'm still testing some settings to make the images flow on various modifiers besides pressure and declination. But so far it's useful for me. It is not as fast as Alchemy, but thanks to Krita it allows a lt more control on the flow of the shapes, sizes and color effects. As well as a nice undo for those shapes you just don't want. I wonder If Krita could get the shapes from an svg like Alchemy does with a pdf.

The "Kit" contains the .gih brushes for each family and one containing all shapes, and a preset for each brush including "all shapes" brush.

Download link from google drive: https://docs.google.com/file/d/0B5HUTZG6uL8iQ0lPNzZUYU1Cbms/edit?usp=sharing

This is my first brush set any feedback is appreciated.

Awesome! Actually, svg integration shouldn't be a huge amount of work.

SVG are actually already supported, just put svg files where you put brushes.

I tried what Lukas replied. Single shape svg are already supported for brushes! wow, I'll try to make something out of this for sure.

@LukasT.dev
Thanks for the tip. I tried them and they work quite nicely for solid shapes or with simple gradients. There is a bug in the spacing settings, it doesn't work properly. All settings from 0.01 to 9.99 have the same spacing effect, spacing has an effect only when 10.00 is selected, but the spacing is massive at that stage.
SVG support is the first stage but, Pull shapes works like this: It takes a shape from a set of vector shapes randomly and place them like an animated brush set. Currently the entire svg shapes are interpreted as a group for the brush tip and cannot be used as a Pull shapes brush source. I guess a check box for setting the behavior of "getting the shapes a group for a single brush tip" or "getting the shapes individually to render as an animated brush tip" would be necessary to keep the current feature working nice.

Another bug I just noticed, Brush rotation modifier does not have antialiasing =(

It's really cool that you're doing these experiments -- you're probably the first to use this feature for real. For any bugs, please bugs.kde.org :-)

Also, I wonder how big these are... Maybe we can ship them by default, once we've got a way to delay loading of brushes.

I just tried them and those seems to work like a charm :D That was only thing I was missing from alchemy. Great job! I really think those should be available from the get go in Krita. Pull shapes with symmetry on and we have concept machine.

@boud
I think they are not so heavy, about 33MB. But to get better results I filled this bugs https://bugs.kde.org/show_bug.cgi?id=319446 https://bugs.kde.org/show_bug.cgi?id=319444 and https://bugs.kde.org/show_bug.cgi?id=319443 . No problem if they are ready for next release :].

@nezumi
Cool! Thanks for testing :] I'm glad it's useful.
