Hey folks, wondering if anyone knows how to do a simple transform in cops. I just want to rotate the image 90 degrees. Seems to be clipped by the frame of the first image when I really want to rotate the frame as well. Love Houdini - hate cops.

Something like this (full scene now)
Use the switch in the cop to compare the results.

Use somthing like
res(“../../../img/comp1/out”, D_XRES) / 100

res(“../../../img/comp1/out”, D_YRES) / 100

in the grid or in your geo, to match the image size in a dynamic way.

You can use the Flip COP, with the “Flop 90 degrees” parameter enabled. This will not only rotate 90', but swap the width & height of the image as well.

Note that even if pixels are rotated out of frame, they're still there for subsequent COPs to use.
