int QccIMGImageCubeExtractBlock(const QccIMGImageCube *image_cube, int
image_frame, int image_row, int image_col, QccMatrix block, int block_num_frames,
int block_num_rows, int block_num_cols);

QccIMGImageCubeExtractBlock() extracts a block of size block_num_frames
by block_num_rows by block_num_cols from image_cube. The block is extracted
such that the low-indexed corner of the extracted block lies at location
(image_frame, image_row, image_col) in image_cube; i.e., a diagonal of the
nominal cube to be extracted would run from (image_frame, image_row, image_col)
to (image_frame + block_num_frames, image_row + block_num_rows, image_col
+ block_num_cols). If any part of the extracted block lies beyond the bounds
of image_cube, the corresponding voxels in block beyond the image-cube
bounds are set to 0.
QccIMGImageCubeInsertBlock() inserts a block of size
block_num_frames by block_num_rows by block_num_cols into image_cube at
location (image_frame, image_row, image_col). Any part of the inserted
block that would lie beyond the bounds of image_cube is ignored, i.e., not
inserted into image_cube.
These routines return 0 on success
and 1 on error.
