Image Creation and Access
4-33
4
headers must be properly constructed and image data for both images must
be allocated; see Example 4-5. The following constraints apply to the
copying:
• The bit depth per channel of the source image should be equal to that
of the resultant image.
• The number of channels of interest in the source image should be equal
to the number of channels of interest in the resultant image; that is,
either the source
coi = the resultant coi = 0 or both cois are nonzero.
• The data ordering (by pixel or by plane) of the source image should be
the same as that of the resultant image.
The
align , height ,and width field values (see Table 4-2) may differ in
source and resultant images. Copying applies to the areas that intersect
between the source ROI and the destination ROI.
