Images
The physical page is the actual medium used, such as a continuous form or
an 8 1/2 x 11 inch sheet of paper.
The logical page is mapped onto the physical page; you can set its size and
position inside the physical page. The logical page contains the image blocks,
text blocks, segment and overlay blocks. A block is an area where the image
is mapped to.
The image presentation space contains the image that will be mapped to the
block. The image presentation space contains the entire image.
An image block can be the same size, larger or smaller than the image
presentation space.

and the mapping of the image presentation space into the image block. You
can specify that the image presentation space fits into the image block or you
can crop a portion of the presentation space and map that to the image block.
