I am looking for a way to first transform an ofImage (which has an alpha channel):
Load a png file into an ofImage, rotate it, translate it and save it in another ofImage.
Then merge this transformed image with another one. I found this topic and maybe I am too tired but it does not do anything…http://forum.openframeworks.cc/t/merging-ofimages/4431/0
Basically as it is explained in the previous topic, I want to do the same as when we draw images on screen, using for example:
imageA.draw(0, 0); ofPushMatrix(); ofRotate(some angle); ofTranslate(someX, someY); ofEnableAlphaBlending(); imageB.draw(0, 0); ofDisableAlphaBlending(); ofPopMatrix();
Does anyone has clues on how to perform such operations? I also found a quite old addon called ofxImage which seems to be doing the transformations I am looking for but I cannot make it work with the current version of OF.
