Some additional notes from my experience in using GhostView to add a
preview. I am running IDL on a Sun Ultra, Solaris 2.7 and running
Ghostview and Office 97 on an NT 4.0.
You can control the resolution of the preview: under Media: Display
Settings, set Resolution. I have found that 150 (dpi) provides a
preview image that displays quit well on screen, e.g. in a Powerpoint
presentation.
Ghostview offers the following preview format options:
interchange: preview does not display
tiff 4: preview in black and white only,
tiff 6: preview in color
tiff 6 packbits: preview in color
Windows metafile: preview in color
The size of the epsi file may be many times that of the original ps
file. However, when inserted into a Word97 or Powerpoint document, the
increase in the size of the file is quite modest (apparently the preview
is compressed upon insertion.)
Here are the relative sizes for a simple line plot in color:
-rw-r--r-- 1 rs 7167 Nov 19 1999 fig.ps
-rw-rw-rw- 1 rs 202213 Nov 18 1999 fig_inter.epsi
-rw-rw-rw- 1 rs 752345 Nov 17 1999 fig_meta.epsi
-rw-rw-rw- 1 rs 104847 Nov 17 1999 fig_tiff4.epsi
-rw-rw-rw- 1 rs 740973 Nov 17 1999 fig_tiff6.epsi
-rw-rw-rw- 1 rs 52336 Nov 17 1999 fig_tiff6_pack.epsi
Be aware that for all except the interchange preview (which is worthless
anyway), Ghostview adds some binary data at the beginning of the file so
that it can no longer be displayed by ghostscript or be sent to a
postscript printer. Also, the previews are binary.
