Storing and Cropping

Storing and Cropping

Store(source, pop)

source: image to be stored (ice.Image).

pop: if false return the sub-image store to. Otherwise return the null image (bool).

Copy the contents of one image into another. Triggers evaluation of source, discards image processing expression of which the operand image is root.

It's important to remember that the data box of the operand image is used to clip the source expression recursively down to its leaves.

Returns either the operand image, or a sub-image thereof.

ice.Image SubImage(box)

box: Rectangular region to be extracted (list).

This operation returns a rectangular sub-region of the operand image as a new Image instance. Data is shared with the operand image, and the data box of the returned image is always at the origin.

ice.Image SubImageWorld(box)

box: Rectangular region to be extracted (list).

Same as SubImage, except that the data box of the returned image is in world space.

ice.Image CopyFrom(src, box)

src: Source image to copy from (ice.Image).
box: Rectangular region over which copy is performed (list).

Returns a new image created by copying a rectangular region from the source image into the operand image. This operation behaves like a "lazy-evaluated store".
