int QccIMGImageComponentExtractBlock(const QccIMGImageComponent
*image_component, int image_row, int image_col, QccMatrix block, int block_num_rows,

QccIMGImageComponentExtractBlock()
extracts a block of size block_num_rows by block_num_cols from image_component.
The block is extracted such that the upper-left corner of the extracted
block lies at location (image_col, image_row) in image_component. If any
part of the extracted block lies beyond the bounds of image_component,
the corresponding pixels in block beyond the image-component bounds are
set to 0.
QccIMGImageComponentInsertBlock() inserts a block of size block_num_rows
by block_num_cols into image_component at location (image_col, image_row).
Any part of the inserted block that would lie beyond the bounds of image_component
is ignored, i.e., not inserted into image_component.
These
routines return 0 on success and 1 on error.
