Tilman Hausherr updated PDFBOX-6156:
------------------------------------
Description:
The result rendering looks like this:
!bitmap-composite-and-xnor.png!
The xnor is detected and works properly, the real cause is that we have a white
region that has the width 141, but the actual width after the blt operation is
144. It turns out that 144 is a multiple of 8 so {{Bitmaps.blit()}}.
