I am trying to mask [rectangle] using GEM with another smaller [rectangle] (that controls the first rectangle's alpha value wherever it is placed) in order to create an adjustable rectangle outline (that has a border of my desired thickness). I noticed that you can choose [draw line( and [width $1( for a rectangle but the maximum thickness of the line is much too small. Does anyone have any thoughts or ideas?
Or maybe there's an object like [disk] (using 4 segments) but with the ability to adjust the height and width just like [rectangle]
Cheers!

hello, you can put an image texture with a rectangle made of alpha pixels, or draw an alpha rectangle using gridflow and then load it as a texture with #to_pix, or snap two rectangles with different colors, and turn to alpha all pixels matching the inner rectangle.

Patrice,
Thanks for your reply, sounds like interesting options (especially the snapping two rectangles together)...could you be more specific with instructions on what objects to use? Pardon my novice GEM skills.
Merci!

Hello,
You have several possibilities to do what you are looking for :
- use (as Patrick describe) two rectangles to create a mask (with
[gemframebuffer], [pix_snap] and [pix_buffer], [pix_buffer_read], [pix_buffer_write]) then [pix_mask] or [pix_multiply];
- use four [rectangle]s to build 'lines' of the rectangle;
- use GLSL to create the mask and the final image.
Surely, there are other ways (like openGL objects with GEM for example)... See in help > browser > examples > GEM (in Pd-extended) to understand what this objects do. Hope that helps somewhat. ++
