[comp.binaries.ibm.pc.d] GIF to BMP?

ao@elixir.lne.kth.se (Anders Ohlsson) (03/20/91)

	Hi there!

	Does anyone know of a program to convert 640x480x256 GIFs to
	BMPs, so that they can be used as wallpaper in Windows 3.0?

	I have tried a program called GIF2BMP version 1.0 (found it
	on garbo.uwasa.fi) but it doesn't seem to be able to handle
	larger pictures than 320x200, it just throws them up...

	Please respond via email to ao@elixir.lne.kth.se.

	I'll be more than happy to post a summary if there's a demand
	for it.

				Thanks in advance,

You got that right - major bomb.

I'd probably give a limb or two for it, especially if it works for
800x600 or even 1024x768.

I have been using PICLAB to convert large GIF's to BMP's.  This's
what I do:

	1. Run PICLAB and load the GIF
	2. UNMAP
	3. set PALETTE 16
	4. PLOAD *windows-palette-file*

		*note: the windows palette file is just a 16-line file
			   containing the RGB values of the windows palette.

	5. MAP
	6. Save the new GIF

The new GIF will be a 16-color picture with the WIndows palette,
which you can use Grafworks (GWS) to convert into BMP format.  I
usually found that the dithering PICLAB performs make the resulting
BMP look much better.  With color pictures, though, the Windows
palette is completely inadequate.  I usually ended up using only
the four gray colors and convert the color GIF into a black & white
BMP.

Hope this helps.

A couple suggestions, first, GIF2BMP works fine for me, I've used it to
convert 1024x768x256 .gif to .bmp files. Maybe your GIF2BMP version is
old, I think mine is ver 1.1, not really sure. You can find it on 
cica.cica.indiana.edu, directory /pub/pc/win3/util. 

There are some other ways to convert gif to bmp. One of them is to use
a program called wingif, the lastest version is on cica, directory
/pub/pc/win3/upload. You can use this program to read in a gif file then
save it as .bmp. There are lots of other ways to do this, I won't mention
them all.

I believe that GrafWorks or Pic Lab (or both?) can do this.  I know _ONE_ of
them does convert GIF to Win3 BMP format because because I used it to do so
and now have several 640x480x256 fractal wallpaper BMP files.

An even easier way is to get wingif from cica. Load the file in (it understands
GIF), then save the file selecting .BMP as the output file type.

Very easy, works for me.
