Hi Friends, I was trying to read pixels from FBO and save it as image with an ofAppNoWindow (headless) instance. However I get a random image. Heres the code,
fbo.begin(); ofClear( 255, 255, 255, 0 ); ofEnableAlphaBlending(); element.draw(); //element is my class fbo.end();
and reading from fbo,
fbo.readToPixels(pixels); pixels.setNumChannels(3); vidRecorder.addFrame(pixels); //ofxVideoRecorder object
both “fbo” and “pixels” are OF_RGBA type.
