HP L 5 manual Source Raster Height Command, ? * r # T

Source 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 6-5).

?* 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 cursor position).

Note

Note

Specifying the raster width and raster height improves memory usage. Therefore it is highly recommended.

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 (this is true only if index 0 is white).

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 filled.

For color printers, a zero fill is not necessarily white.

If the raster height is not set, no padding or clipping of rows takes place.
