Compuprint 4247-Z03 Programmer Manual - Manual (Page 174)

Notes:
1. The printer will not rescale graphics image data. If the image data does not fit within the output area,
clipping of the image data occurs.
2. Graphics markers are not scaled; they are always 3 mm (0.12 in. [17/144-in.]) square. If markers are
drawn close to the boundary of a page and the page is then scaled down, the center points of the
markers are scaled closer to the boundary of the page but the marker size is still the same. The
markers may be clipped from the page if the scaling factor scales the centers of the markers too close
to the edge.
Center and Trim Mapping: The center of the graphic window is mapped to the center of the graphic
block area and the graphic data is presented at the specified scale. Any portion of the picture that goes
outside the graphic block area is clipped to the graphic block area boundary. Figure 24 on page 155
shows the result of center-and-trim mapping. For this example, the graphic window is shown smaller than
a previously defined graphic picture. This picture is to be placed on the physical medium. The parameters
in the Graphic Data Descriptor specify the size of the graphic window (in graphic medium presentation
space (GPS) units). The parameters in the Graphic Area Position and the Graphic Output Control specify
the size and location of the graphic block area on the physical medium.
If the graphic block area is smaller than the graphic window, as shown in this example, a portion of the
graphic picture is eliminated. The centers of the graphic window and the graphic block area coincide, and
the boundaries of the graphic block area determine the limits of the graphic picture. Any portion of the
graphic picture extending beyond the graphic block area will not be drawn on the page.
