Items in CAPS are 0/1 switches or switches with more options than 0/1. |
Unmodified Image |
Bend of .7 with Bottom Base and Wrap on |
|
Bend Amount
This is a floating point number where 1.0 represents the exact width or height of the image, which one depending on the base.
Base of Bend
This sets the side of the image that the bend emits from; the image is bent away from this side.
Wrap
This tells the operator if pixels that move off on one edge should be wrapped back into the image past the opposing edge.
Insert Alpha
If Wrap is off, then the question arises: What to do with the region that the image data has moved away from? You can either leave it the same as it was, or you can make it transparent. That's what the Insert Alpha checkmark causes to happen.
