Hi Netters,
Does anyone one out there knwo whether the '.gif' format is supported
on the Atari St. I really want to be able to convert from popular standard
Atari formats such as Degas or Neochrome to '.gif' and back again.
And also is this '.gif' format the same as that used on Sun Work -
Stations??
I have looked on Lancs.pdsoft, but they only seem to have GIFFER ,a
display program for '.gif' pictures.And also Picswitch doesn't seem to support
the '.gif' format.
And lastly does anyone know why they are called '.gif' ???!???
Alan.

I believe Alpha Systems sells it. It will take a .gif file and convert it into a .sps file (spectrum 512). It will then look about as good as it can on the ST (it takes some time to process each picture). The resulting .sps file is usually MUCH smaller than the original .gif. There is a PD viewing program available for .sps files which also can compress them into .spc files (I may be backwards about .sps and .spc, now that I think about it!). Anyway, if cannot find an add for this company, send me email and I will dig it out. Oh, I checked out a couple of PD .gif file viewers, and none that I saw even came close to the job that Digispec does. Usually, .gif files are scanned in at a resolution (and with more colors) than the ST can display. Thus, any viewing/converting program must convert the file the ST's resolution, and reduce the number of colors to 16. Digispec converts them to have 512 colors, which really makes a difference! All the PD programs I have seen use only 16 colors, which is what the ST was designed to display in low rez (16 on the screen at one time). Hope that helps! -- Mickey R.

If any body is intrested I will UUencode the stuff and send it to those intrested. I will ARC it then UUencode.

Hope that >helps! My program, GIFSPC, and BGIF (sorry, forgot the author) will both use up to 512 colors when converting from GIF to Spectrum. From what I can tell, it looks like BGIF only uses 16 colors per scan line, whereas GIFSPC will use all 48 allowed if it can. (Anyone know for sure about that?) If you can't get GIFSPC through anonymous FTP, I'd be happy to Email it to you.

A few corrections: First, Digispec is from Trio Engineering, the creators of Spectrum 512, and costs ~$40. Its primary purpose is for use with their digitizer; gif conversion is an add-on. Second, it will let you save the result as either an _.spu_ or an .spc file, the latter being the default. Every Spectrum viewing program I've seen will work with either of these. Sps is a more compressed representation, apparently _not_ developed by Trio; .sps files require spslidex (PD) to view or convert, I'm told. Digispec does indeed do a better job, not surprisingly, than the PD converters Bgif and Gifspec. The picture quality is better, the files are smaller, and you can adjust brightness, contrast, color mix, and dithering scheme as desired. On the down side, it cuts the top or bottom (your choice) off of tall gifs, and it screws up the aspect ratio on the most un-square gifs. I've seen enough questions on this issue (including my own, a few months ago) to think there should be something in a periodic FAQ posting on it.

Hi, there is are .GIF viewers for the ST. Two which I know of are Fast Gif and
View Gif. You should be able to get it from most boards around, if not you
can write to:
