Hello all.

I want to load an image and them retrieve the pixel data (colour) of the individual pixels using coordinates. I've tried pix_data and that doesn't seem helpful. I get some values, but they are not what they're supposed to be. Is there any other object I can use to retrieve pixel data?

To clarify: I don't want to display the image as it is, I want to build sort of a "LED"-scroller of cubes and use images as input (much easier if I want to animate I guess...).

Any suggestions?

tried sending a bang to pix data in the 1st inlet? that had me stumped at first

hi, maybe you might want to take a look at this "scanner" i made
http://puredata.hurleur.com/sujet-3150-webcam-sequencer
it uses pix_data and only looks for black n white, but maybe there is some usefull stuff inside which you could use.

would be really nice of you, if you post your results. it's interesting stuff and kind of tricky to do, i guess.

I got it working now. I'll post it as soon as it is finished.

I've posted a new thread with my patch as it is now.

this sounds like a job for Gridflow!
