Re: [PD] A system to read individual pixels from an image
Merhaba Batuhan, To my knowledge, there are ways to do that in GEM. - Loading images to see them in a window comes in pretty easy. Just use the [pix_image] and/or [pix_multiimage} to actually load the stuff (I personnaly use the tiff format for uncompressed images). Then use [pix_texture] to apply them to a basic GL shape like [rectangle] or [square] depending on the aspect ratio of the picture. Building a subpatch/abstraction that detects this ratio and adapts the rectangle size accordingly shouldn't be very complicated, I have an abstraction hanging around that I could give you if you wish. - Getting pixel color can apparently be done with [pix_data]. See help file, never used it yet... - [gemmouse] is your friend to get mouse coordinates and button information from inside the gemwin. ++ Jé Batuhan Bozkurt a écrit : Hello, I'm mostly using the audio capabilities of PD and now I need this functionality to port my image synthesizer I've made in Max/MSP before(which was a pain while building because of the audiorate rounding errors in Max/MSP) to PD. I was using the LCD object in there. The functionality I need is: * I want to be able to read images into a window to see its contents(being able to load uncompressed images are enough) * A message like getpixel x y should return me the RGB values of that pixel * It would be nice to be able to draw single pixels with mouse at least...(can be implemented with something like setpixel x y r g b I know that people are doing fancy stuff with GEM and other libraries but I really don't know what to chase for this simple task.
