Hello all,
I was wondering if there is an object in GEM that will allow Pixel level addressing in a "Pixie" (that is what GEM calls images, right?)? I know there is a way to create an entire image from a list of numbers, but that only appears to do a complete images, and not addressable at the pixel level.
If this is NOT possible, is there some other object/external that will allow the display and manipulation of images at the pixel level?
Thank you,
Mike M

GridFlow can do this.
Most GridFlow objects operate on whole grids (of which images are a subset), but there are ways to get regions from grids (using #store) and ways to put regions back into a certain place in an image (using #draw_image).
There is also a Gem<->GridFlow bridge (part of GridFlow).
Thank you,

how do you create a whole image out of a list of numbers?

In GridFlow:
list with 240*320*3 elements all of which are floats | [#import ( 240 320 3 )] | grid with height 240, width 320, 3 channels.
You can also feed the floats to [#import] individually or in smaller groups than a whole image, it will output the grid when it has got just enough, and any extra count towards the next grid.
I'm not sure how to do it in Gem.
