Hello,

I'd like to know if it's possible to be able to change the diameter/size of a brush with a slider like opacity/distance?

Sure, you want Brushes palette :)

There is a button to open brush editor in its left bottom corner

Unfortunattely, that only works for ".vbr"s - which stand for "virtual brushes" - simple, algorithmic, brushes - which have a basic shape (diamond, square, ellipse, all with N points).

This is a missing feature for standard bitmap brushes. The code is even there, but currently it is used only with pressure sensitive input devices, and it lacks a UI for using with ordinary mice.

However, in another gimp-list, someone is saying that had accomplished a "brush resizing" script-fu.

In this folder: http://groups.yahoo.com/group/script-fu/files/Scripts/

The file "resizebrush.scm" (I hope it is open for non subscribers of the list).

It doesn't make too much sense to scale bitmap brushes, does it?

IMHO it does. Why not?

See - I have this "digit" animated brush - just a set of 0 to 9 numbers in some pretty font, sprayed in random order. The brush size is just one, but depending on the desired effect, and the image size I am working on (for online viewing or for printing), I need a different size of the brush. With the current features opf the GIMP I need to make a new version of the brush for each size I wish to use it.

There is a feature request in bugzilla about a Curves UI to control various brush variables - I hope we can implement that someday.

IMHO, If it was the same as a truetype font and the bitmap brush was 300x300 pixels, maybe; because we'd always scale down and there'd be no attempt to up-scale and try and make a better brush from a brush with less data. [Loss of quality is another issue, meaning that you can only have so much data there...] If you have a 8x8 brush and want to draw something that is 80x80, that is a completely different matter.

Of course, scaling would make so much sense with SVG/Vector brushes -- but then, GIMP is a raster graphics program. No-win situation. *sigh*

If the code is there, and it is possible to get at it using another device; it doesn't seem to me for it to be unreasonable to provide mice-based and/or keyboard-based ways of providing the same funcationality... but that said, it has to be done within limits or users will simply get confused and/or complain about weird things.

Why's that a no-win situation? GIMP could easily be extended to use SVG brushes and that would certainly be a win. We could still keep bitmap brushes around because there are some brushes you cannot express easily using vectors.

Of course it could be done. Someone just needs to write the code.
