ippStsSizeWrn
Partial geometry, not an invalid-size error
ippStsSizeWrn is a positive warning. In current resize and geometric-transform documentation it is used when a destination image or ROI extends beyond the original destination bounds, so the full requested operation cannot be performed. This differs from ippStsSizeErr, which rejects a zero, negative, or otherwise invalid size.
A successful return test alone can therefore hide clipped output. Callers that expect every destination pixel to be written must compare requested and effective bounds.
What to record
- Destination origin, requested ROI, original image size, and the clipped region actually processed.
- Tile offsets after scale and rounding calculations.
- Whether untouched destination pixels were initialized before the call.
- Whether the warning is acceptable for an edge tile or indicates an incorrect output allocation.
