Re: ps2raster error abot Chinese characters

Hi,

I test it with GMT 5.1.1 under my Windows 7.

Below are my five tests:
1.    gmt ps2raster test.ps
                             FAIL
2.    gmt ps2raster *-C-sFONTPATH=C:\Windows\Fonts* test.ps
        SUCCEED
3.    gmt ps2raster -C-sFONTPATH=C:\Windows\Fonts test.ps -P test.ps
  SUCCEED
4.    gmt ps2raster -C-sFONTPATH=C:\Windows\Fonts test.ps -P -Tg test.ps
 SUCCEED
5.    gmt ps2raster -C-sFONTPATH=C:\Windows\Fonts test.ps -P* -A* test.ps
  FAIL

In test 1, it fails.

In Test 2,3,4, I use -C option to pass FONTPATH to gs, so that gs can find
the Chinese fonts and correctly
do the conversion from ps to pdf, jpeg or whatever.

But, in test 5, when I use -A option to adjust Bounding Box, I get errors
same as you mentioned in your first email.

In fact, I get one more error message, and it is very important, it is:

"
ps2raster: System Call [@"C:\Program Files\gs\gs9.14\bin\gswin32c.exe" -q
-dSAFER -dNOPAUSE -dBATCH -sDEVICE=bbox test.ps > ./ps2raster_3432c.bb]
returned error 1.
"

When the -A option is used, ps2raster will use gs command above to
determine the Bounding Box of PS files.

I tried to run the command out of ps2raster,

    "C:\Program Files\gs\gs9.14\bin\gswin32c.exe" -q -dSAFER -dNOPAUSE
-dBATCH -sDEVICE=bbox test.ps

it gives the same error.

Then I tried to add FONTPATH option to this command,

      "C:\Program Files\gs\gs9.14\bin\gswin32c.exe" -q -dSAFER -dNOPAUSE
-dBATCH -sDEVICE=bbox *-sFONTPATH=C:\Windows\Fonts* test.ps

it correctly determine the Bounding Box.

So, my conclusions are:

1. Under Windows, the FONTPATH is needed for Chinese support.
2. Maybe there is a bug of ps2raster, it forget to pass -C option to gs
command when deal with bounding box.
