Scrolls right or left within the defined window by
nPix
number of pixels. The opposite edge of the
scrolled window will be filled in with white pixels. The window must be byte-aligned.
Paramters will be verified for the following:
1. The left and column paramters will be verified that they are evenly divisible by 8. If not, they
will be changed to be a value that is a multiple of 8.
2. Parameters will be checked to verify that the scrolling area is valid. The minimum scrolling area is
a width of 8 pixels and a height of one row.
PARAMETERS
left is the upper left corner of bitmap, must be evenly divisible by 8
top is the left top corner of the bitmap
cols is the number of columns in the window, must be evenly divisible by 8
rows is the number of rows in the window
nPix is the number of pixels to scroll within the defined window (negative value to scroll left)
SEE ALSO
