[comp.graphics] Help with cvtgif .PCX -> .GIF converter

jap7g@mendel.acc.Virginia.EDU (Jim A. Pisano) (06/20/89)

I am trying to convert .PCX (PC Paintbrush) images to .GIF images so
that I can display the same image on different monitors, something that
brain-dead Paintbrush can't seem to do :^(.

Alas, cvtgif doesn't work - I get the following message when I run cvtgif:

IMAGE.PCX  Loading...External Memory allocation overflow, 1016K requested,
289K free

I've tried this on 2 computers 1 with 1.5MB of extended memory and the other
with ~ 4MB of extended memory.  I tried using the program with my memory
configured as both extended AND expanded (LIM 4.0 & LIM 3.2) memory, but
to no avail.  I also tried to images.pcx; one was ~500K and the other was
about 300K - both files requested the same amount of RAM (1016K) which
seems pretty extreme.  Do I need a EMS board that uses bank switching 
hardware or should I run straight extended?

Any and all help would be greatly appreciated.

-Jim

 Jim, use the FBM package. I think that the FBM pipe should look like:

    fbsample -n2 -g1 <file.pcx | fbnorm | gray2clr -G >file.gif

   (play with values of -n , try 1 2 3 4 )

 The FBM package was posted on comp.sources.unix about two weeks ago.
 I heartily recommend the FBM package, It very works well for me.
 I also recommend the PBM package which (I beleive) was posted to comp.sources.unix
 a while back. I beleive that you can also FTP the PBM package from expo.lcs.mit.edu
 along with the Poskanzer bitmap collection (which I also recommend).

 Thanks go to Michael Mauldin (FBM) & Jef Poskanzer (PBM) for these much needed packages!

 I would also recommend that anybody considering format conversion check out these packages.
 The PBM package is a good base for monochrome conversion. The FBM package is an EXCELLENT
 base for color format conversion. It is fairly easy to add new formats. I have written
 several programs to work with the FBM package, and it aas very straightforward.

Has anyone gotten FBM to work on an Amiga? If so could they send me the
executable and docs? I have no ftp access, so I have to rely on the goodness of
someone out there to help me through Email. 

modified Amiga source code would be a nice extra, too. 

Thanks

Jim, this might not be  t h e  answer to your problem, but you can 
convert pcx to gif with a screen capturing utility (SCR2GIF) which 
was written by Bill Fleisher and is on many BBS's. I do this all the 
time, and even though this is a TSR program, I've never had any problems 
converting to GIF this way...
