Using Graphics - Brother HL-Series Technical Reference Manual

Revision C 16/01/96

Using graphics

This HL Series printer affords the user considerable flexibility in the creation of graphic images. Vector, raster and
rectangle graphics are available, all of which allow a range of shading and filling options. The HP-GL/2 graphics
commands that are supported are described in the HP-GL/2 section of this manual.
Source, pattern and destination
We refer to a printing model in which a source image (the image to be drawn) is applied to a destination image
(simply the graphics or text that already exist on the page). The source image consists of white space and non-
white areas. The non-white areas are covered by a pattern of some description. The pattern may simply be solid
black or it may itself consist of white and non-white areas, for example the pattern may consist of vertical spaced
lines. You can specify the way in which the white and dark areas of the entire source image and the white and
dark areas of the pattern interact with the destination image to produce the finished effect.
