All,
I'd like to create what should be a really simple quartz composition, but keep getting stuck--I'm new to this. I'm hoping someone can steer me in the right direction...
In the end, I need a QuickTime movie that is 304 pixels by 304 pixels square. That's a 300x300 video image with a 2 pixel white border all around. Like a mirror, the image should be flipped horizontally. When loaded in a web browser it should automatically display the user if their iSight is on. Anyway, you get the idea.
I've got the rest of the patches working, but...
I can't flip the image horizontally.
I can't crop it to 300px x 300px.
I can't add a 2px border.
Any help would be appreciated,
THANX in advance!!!

You can flip the image horizontally in a couple of ways:
1. Use a "Sprite" output and set the Y rotation to be 180
2. Put the patches in a 3D Transformation patch and do the same thing
3. Use a Core Image Kernel
You can "crop" using a Crop patch.
You can add a border either by putting two Sprite/Billboards on the screen, one 2 pixels wider than the other, or by using a Core Image filter (potentially the same one you used to flip things to increase performance. |

Use an Affine transform with negative values for the x scale size
