Re: ps2raster error abot Chinese characters

hi,Dongdong Tian
Thanks very much for your work. 
The option I used in ps2raster was  'gmt ps2raster cn.ps -P -Tg -A' and it caused the error I mentioned. 
Now adding '-C-sFONTPATH=c:\windows\fonts' and remove '-A' of ps2raster can correctly output figures of other formats. This is not perfect but is successful. 
Hope someone can fix this bit bug of ps2raster (if it really is a bug and not a wrong user's operation).
Cheers

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.

Now I can use  GMT to make ps format figure with Chinese Character correctly after I learned the example 31 and some blogs about this.
But while using ps2raster to convert ps to PNG format the error comes as the last letter mentioned. I guess this is a problem of ps2raster and it happens when ps2raster call the ghostscript to find Chinese characters.

here http://hi.baidu.com/flyfish551/item/312e9bd3104224f193a97425
is a post on GMT chinese support (in english)


Quoting Paul Wessel <[email protected]>:


Presumably ghostscript cannot find the file with the metrics of the  Chinese characters? Are these installed?  While I don't know how  this all works, we have a GMT example that shows the use of Cyrillic  alphabet (example 31) which provides its own files for those  characters.  Perhaps studying that example can give you some hints.

Dear GMT users,

When I convert the PS format figure containing Chinese characters  to other format like PNG or TIF, there is a error:

Error: /invalidfileaccess in /findfont

Current allocation mode is local
Current file position is 17236
It implys that this error is related to 'STSong-Light--GB-EUC-H'  which is a kind of Chinese font. But I have no idea how to fix it.
Would anyone please give some help?

PS: I use Window 7+GMT5.1.0
