Re: Follow Path With Perspective Brush Script for GIMP

It's all based on the Y-coordinate, if the Y-coordinate is closer toward the top then it tries to use smaller brush-size based on your minimum brush size setting, if the Y-coordinate is closer to the bottom then it tries to use larger brush-size based on your maximum brush size.

Unless you specified a larger number for minimum and a smaller number for maximum, then it's reverse which gives the illusion like on the ceiling effect, where everything is reversed in sizes (closer to the top would look larger and closer to bottom would look smaller).

Still doing the "learning curve" practice. Is this better now? I had to get it into my head that you were not asking for sizes, but percentages of the sizes regarding the brush and spacing. Then it made more sense to me as to what I am doing.

Yeah i don't know why i chose percentages over explicit size. I guess when you're adjust brushsize you hover over your image to see how large the brush really looks and then i just ended up thinking in terms of percentage relative to that size.

Are you talking about the leaf scribble I did in the post above? If so, it was very primitive just practicing. I have a autumn leaves brush pipe and played with it to see the spacing I would need to make a solid line depending on the size of the leaves I wanted to make. I then made some paths. You can use the path tool or the path shape maker scripts to do that. I then used Tin's script: Follow Path with perspective Brush Script for Gimp.
How it works made sense to me after I read Tin's first post of this thread a few times.

If you like the leaves brush, I am attaching as it has the different colors that are so pretty for Autumn.
Let me know if I have answered what you were asking. I really like Tin's script.
