[bug-gs] How to add HalftoneType 3 to gs_init.ps?

[Janssen, Norbert]

Hello Support,

I try to add a HalftoneType 3 to the gs_init.ps file but get the
following
error  (on gs8.54). In the gs_init.ps the following code is added:
+++ start gs_init.ps code

% Load the standard font environment.
%% Replace 1 (gs_fonts.ps)
(gs_fonts.ps) runlibfile

(END GS_FONTS) VMDEBUG

% Load my halftone definitions
(my_halftone.ps) runlibfile

+++ end gs_init.ps code

Put the my_halftone.ps file (see attachement) in the current directory
(this is also
searched), or in the share/ghostscript/8.54/lib (next to gs_init.ps).
Then do

gs -DDEBUG

and this gives the following error:
+++ start error output
while reading my_halftone.ps
Error: /syntaxerror in -file-
Operand stack:
   MyDefaultHalftone
Execution stack:
   %interp_exit   --nostringval--  --nostringval--  false  1
%stopped_push
Dictionary stack:
   --dict:702/1123--  --dict:61/200--  --dict:702/1123--
Currnet file position is 40803
Unrecoverable error: undefined in .uninstallpagedevice
Operand stack:
   MyDefaultHalftone
+++ end error output

Placing the contents directly in the gs_init.ps gives a similar error
(--nostringval-- and the undefined in .uninstallpagedevice).

This .uninstallpagedevice is in gs_setpd.ps, but as far as I understand
it, the error is
happening while loading the my_halftone.ps.

Can someone see what I am doing wrong?

Thanks and greetings,
