4.5. CONTROLLING THE MASK OBJECT
The mask object consists of a horizontal masked area at the top and bottom of the raster, and a vertical
masked area at the left and right side of the raster. Throughout the remainder of section 4.5.2.2 the mask
dimensions refer to the boundaries between the masked and unmasked area as shown in Figure 4-4. The
left side of the mask is the first unmasked pixel; the right side is the last unmasked pixel. The top of the
mask is the first unmasked line and the bottom of the mask is the last unmasked line. The horizontal
transitions from mask to image are shaped as shown in Figure 4-4. The vertical transitions from mask to
image are hard transitions.
