Hey,

i want to make a random landscape generator. Is it possible to draw direct to the Image or need i the grabScreen() methode?

Thx for informations.

The solution is to work with the ofxFBOTexture addon.

Then you can draw in the Buffer like this:

ofxFBOTexture buffer;

buffer.begin();

ofSetColor(0, 255, 0);
ofRect(0, 0, 50, 50);

buffer.end();

buffer.draw(0,0);

I hope this is the right way to work with.

thx and ciao

This wasn’t the correct solution. I dont know how to manipulate the FBO Pixels. There is no methode getPixels() or so…

Help please.
