Hi, I'm trying to display two images, one on the top, and one at the bottom of the screen in Psychtoolbox. I know how to do that already with the right and left sides of the screen. The code for that is below. Any advice would be appreciated!
[imageHeight,imageWidth,colorChannels]=size(ImageDataData);
gap=100;
leftRect=[xCenter-gap-imageWidth,yCenter-imageHeight/2,xCenter-gap,yCenter+imageHeight/2];
rightRect=[xCenter+gap,yCenter-imageHeight/2,xCenter+gap+imageWidth,...
yCenter+imageHeight/2];

The values are the x,y coordinates of the top right coordinates of the rectangle the x,y coordinates of the bottom left coordinate of the rectangle
topRect = [xCenter-imageWidth/2, YCenter-gap-imageHeight, xCenter+imageWidth/2, Ycenter-gap];
bottomRect = [xCenter-imageWidth/2, Ycenter+gap, xCenter+imageWidth/2, Ycenter+gap+imageHeight];
