I would first try flattening the image by writing the pixel buffer into a float array. Then send the width and height as well for reading it back in pd. There currently isn't a way to send an area of memory and I could imagine sending a giant list would be alot slower then using an array.</div><div><br></div><div>See the example in <a href="https://github.com/danomatika/ofxPd">https://github.com/danomatika/ofxPd</a> for how to read/write to pd arrays.</div><div><br></div><div>Otherwise you could write and external as Mathieu suggests ...</div><br><div><div>On Aug 27, 2011, at 11:21 PM, Mathieu Bouchard wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div>On Sat, 20 Aug 2011, ronni montoya wrote:<br><br><blockquote type="cite">Hi , Do anybody is working with openframeoworks and libpd? i would like to develop an application that interpret pixels as sounds using libpd addon on openframeworks.
