Raster Height Command

The Raster Height command specifies the height in raster rows of the raster area. Height is the direction perpendicular to the direction that raster rows are laid down, hence, height is subject to the current raster presentation mode and print direction (see Figure 15-7).

EC * r # T

#= Height in raster rows

Default

=

N/A

Range

=

0 to (logical page length – current Y-position of the

 

 

0,cursor)*

*Greater values default to (logical page length – current Y-position of the cursor)

This command fills the raster area to the full raster height with zeroed rows. Unspecified rows map to either white or transparent depending on the source transparency mode.

 

When a Transfer Raster Data command is received that causes

 

any raster row to extend beyond the row boundary set by the Raster

 

Height command, the row outside the boundary is clipped. This

 

includes the case where the cursor is moved beyond the height

 

boundary with a Raster Y Offset command and the printing of raster

 

data is attempted.

 

If you have specified either a raster height or a raster width of 0

 

and a Start Raster Graphics (or Transfer Raster Data) command is

 

received, then the entire raster graphic is clipped. If both a raster

 

height and a raster width are specified (non-zero) and a Start Raster

 

Graphics (or Transfer Raster Data) command is received then the

 

raster area is guaranteed to be logically zeroed-out.

 

If the raster height is not set, the raster height is ignored so that no

 

padding or clipping of rows takes place.

 

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.
