EN Raster Graphics 6-15
Source Raster Width Command
The Raster Width command specifies the width in pixels of the raster
area. Width is in the direction that the raster rows are laid down,
hence width is subject to the current raster presentation mode and
print direction (see Figure 6-6).
? * r # S
* Greater values default to the (logical page width – left graphics margin).
Note Specifying the raster width and raster height improves memory
usage. Therefore it is highly recommended.
This command allows you to implicitly tell the printer to pad raster
rows that are not specified for the full raster width with zeros.
Unspecified data maps to either white or transparent depending on
the source transparency mode (this is true only if index 0 is white).
Note For color printers, a zero fill is not necessarily white.
When a Transfer Raster Data command is received that specifies a
row of data that is longer than the raster width, the data that extends
beyond the raster width is clipped.
This command is ignored after the Start Raster Graphics or Transfer
Raster Data commands, until the next End Raster Graphics
command.
Note Only raster data appearing within the intersection of the logical page,
the printable area, and if set, the raster width and height is printed.
Data outside the intersection is clipped.
# = Width in pixels of the specified resolution
Default = depends on raster presentation mode: when
presentation mode is 0 then width = width of logical
page minus left graphics margin; when presentation
mode is 3 then width = dimension of logical page along
paper length minus left graphics margin.
Range = 0 to (logical page width minus left graphics margin)*
