The Gaussian Blur Example breaks when mixed with rectmode center

I am working with the gaussianBlurFilter example.

I am applying a guassian blur filter to an image. Everything works fine.

**However, when I set ofSetRectMode(OF_RECTMODE_CENTER), the image doesn’t show up on the screen anymore.**Any ideas what might be happening? Does this shader not support OF_RECTMODE_CENTER ?

This is how I am drawing the image once OF_RECTMODE_CENTER is on:
image.draw(ofGetWidth()/2, ofGetHeight()/2, ofGetWidth(), ofGetHeight());
