ImagePartition

ImagePartition[image, s]
partitions an image into an array of s×s-pixel subimages.

ImagePartition[image, {w, h}]
partitions an image into an array of subimages of pixel width w and pixel height h.

ImagePartition[image, {w, h}, {dw, dh}]
uses pixel offsets dw and dh.

ImagePartition[image, s] generates as many s×s subimages as possible, dropping incomplete subimages at the edges.

In ImagePartition[image, {wspec, hspec}, ...], the following forms can be used for wspec and hspec:

	s	allow only size s
	{s}	allow any size up to s
	{s_min,s_max}	allow any size s_min through s_max

The default setting is Padding->None, which drops subimages at the edges whose sizes are not consistent with {wspec, hspec}.

Partition an image into blocks of size 16 by 16:

Partition into equal-size blocks, dropping some pixels at the borders:

Partition into blocks not larger than the specified size, including all pixels from the image:
