Adding colors to wpc_ps

[tkbd]

I'm sorry.
I tried the sample files in my HDD,but I couldn't find it because too old date.
Unfortunately, I can't use GoogleDrive in my current environment.
but,I can send you a test file if needed.
You can also tell me your email address through direct message of the Wings3D forum.


FYI:
I tried to read PS/EPS files that created by various vector graphic Editors.
I test MacOSX mojave and Wings3D 2.2.9 and installed your latest wpc_ps.tar

Perhaps it treat too strigt to the data that SVG "creator" directive.
So,many EPS/PS test files could not be read.
These could be read by the Wings3D built-in EPS/PS importer before your version installation.
I'll post some console output and the beginning of the file.

Some PS/EPS files output error(It is no crash but file loading failure)
The example in Wings3D console

Code:

{179,164},
                         {178,179},
                         {177,178},
                         {176,177},
                         {175,176},
                         {174,175},

It generally knowns that a PostScript file create by Print dialog with printer driver too.
They append something string to "%%Creator:" directive of the PostScript file.
Some printers or applications add string with unknown character encoding,then mojibake happen
In the case,Wings3D refuse it that even correctly PostScript data part.
In this case,PS format convert from PDF file...



Wings3D console (for example)

Code:

wpc_ps: EPS Creator: "(\343\203\225\343\202\232\343\203\254\343\203\222\343\202\231\343\203\245\343\203\274: CGPDFTOPS CUPS FILTER)"

Oct:343/203/225 -> Hex:E3 83 95 -> UTF-8:E38395 -> フ

The octal data "\343\203\225\343\202\232\343\203\254\343\203\222\343\202\231\343\203\245\343\203\274"
means the UTF-8 code(hex) as "E38395,E3829A,E383AC,E38392,E38299,E383A5,E383BC"
,and it stands for the string "フ゜レヒ゛ュー"
it is a built in viewer application of MacOS
