CHAPTER 4 HP-GL/2 - 36
With screen type 21 option 1 specifies one of six predefined PCL cross-hatch patterns (patterns 1 - 6).
option 2 is ignored.
With screen type 22, option 1 specifies the ID number of PCL user-defined pattern which is defined by the
ESC*c#W command. option 2 is ignored.
With fill screen type 130 option 1 specifies the percentage of shading ( 0 - 100 ): option 2 is ignored.
If option 1 and option 2 are omitted, the most recently specified values for these parameters, for the
specified screen type, are used.
All screening patterns use the current anchor corner.
Invoking the command with no parameter turns screening off. This is equivalent to SV0;

TR - Transparency mode
TR [ n ] [;]
n ; transparency type
This command turns transparency mode on and off. Transparency mode defines how source and
destination graphics images interact.
n is either 0 (off) or 1(on).
When transparency mode is on, the white parts of a source image (the image that is being superimposed on
the destination image) do not affect the destination image - that is, part of the destination image will be
visible beneath the source image.
When transparency mode is off the destination image is not visible beneath the source image.
Invoking the command with no parameter turns transparency mode on. This is equivalent to TR1;
An Esc E reset, a control panel reset, the IN command and the DF command all turn transparency mode
on.
