Tgif FAQ - Export Windows EPS File
|
| |
|
When I insert the EPS file
generated by tgif in Word or other Windows applications, I cannot
see the content of the EPS file. Is there a way to have tgif
generate a Windows friendly EPS file?

If you set the following X defaults (I can't remember if all these are
necessary):
- Tgif.UsePsAdobeString: 3.0/3.0
- Tgif.HalfToneBitmap: true
- Tgif.BitmapThreshold: 0.5
- Tgif.TiffEPSI: true (<-- don't need this
if you are running tgif-4.x)
and you print into EPSI format, you will get an EPS file which can
be used in Windows. I've tried this with Word and it seemed to work!
With this setting, before the EPS file is generated, tgif generates an
XBM representation of the file and look at the Tgif.XbmToTiff X default
to convert the XBM file to a TIFF file. A small header is then prepend to
the EPS file and the TIFF file is appended to the EPS file to generate
a DOS/Windows EPS file. The default Tgif.XbmToTiff X default is:
- Tgif.XbmToTiff: xbmtopbm %s | pnmtotiff -none > %s
Xbmtopbm and pnmtotiff are from the
netpbm toolkit.
Please remember that an EPS file only works when you
print with a PostScript printer!

I have an Windows EPS file
generated by Adobe Illustrator 8. When I try to import it,
tgif says, "unable to convert EPS preview bitmap". If I run
"eps2eps" on the EPS file, tgif can then import it. Is there
a way to fix this so that tgif can import it directly?

Usually, a preview bitmap in a Windows EPS file is a greyscale
image. The default way tgif process this is to run:
- tifftopnm %s | pgmtopbm | pbmtoxbm
where %s above is replaced by a temporary filename
created by tgif.
Apparently, Adobe Illustrator 8 generates a color
preview bitmap. So, if the above command is run,
pgmtopbm fails because the image is in color.
To get around this problem, please use the following
X resource:
- Tgif.TiffToXbm: tifftopnm %s | ppmtopgm | pgmtopbm | pbmtoxbm
Once this is used, you need to comment it out if you
want to import Windows EPS files that use a greyscale preview bitmap.
