, the segment record is not
needed, since Labelpoint decides automatically where to store the graphics file.
Graphics format
Graphics are stored as bit-mapped graphics, where a bit set to 1 represents a black dot on
the paper. The actual bit-map is preceded by a table, which specifies the height and width of
the logo.

the bit-mapped graphic data
The bit-mapped data is stored 8 bits per byte with the specified number of bytes per row.
Thus the total number of bytes required for the bitmap will be equal to the row length times the
height of the pattern.
The figure below shows how each bit in the bit map corresponds to a dot on the paper.
