AddOpImage
.
The layout
parameter may optionally contains the tile grid layout, sample model, and/or color model. The image dimension is
determined by the intersection of the bounding boxes of the two source images.
The image layout of the first source image, source1
, is used as the fall-back for the image layout of the destination image. Any
layout parameters not specified in the layout
argument are set to the same value as that of source1
.
source1
- The first source image.source2
- The second source image.layout
- The destination image layout.useROIAccessor

- Cobbled sources, guaranteed to provide all the source data necessary for computing the rectangle.dest
- The tile containing the rectangle to be computed.destRect
