Jay Rosenberg complains that the recently-posted vgif program terminates poorly after drawing a pretty picture on his EGA card. My addition to this: I'm using vgif on a CGA card (Z-158 display, actually). When I use vigf's 2-color option, it appears that the lower portion (one-fifth, maybe?) of the picture is missing. That is, the screen is filled, but the picture looks like it should extend lower. AND, when I try the 4-color mode, the picture is twice as wide as the screen -- I can see only the left half of (the upper part of) the same picture. Can anyone explain this to me? Also -- there was a showgif program posted a couple of weeks ago, supposed to be a CGA viewer. It looks sort-of like it's in uuencoded form, but there's a "table" keyword and a list of printable ASCII characters preceding everything else. I tried uudecoding it anyway, but the result hangs my machine so that I must soft-reboot. So, What is this program? What format? Does it work? ____ "I've been trying to remember if I was stoned tonight." - Zonker

[more stuff cutout] A lot of GIF files are intended for EGA (640*350) displays. When you tell VGIF to display the file, it just displays the upper-left hand corner. You can tell what size the file is by loading VGIF, changing the misc. options (I think that's what it's called) and telling VGIF to display statistics about the pictures before displaying them. For example, the blastoff.gif file is 640x350 16-color (if I remember right). The only way I know of to see the rest of the picture is to use a computer with a better video system (no scrolling exists in VGIF). Hope that this helped. Mark

This is *normal* behavior. Your screen only has 200 lines of vertical display,
EGA, Herrcules, VGA, and some "special" cards will have more lines of data
(typically 350, though I've seen 400). This means that the picture gets
truncated at line 200.
The horizontal problem is similar. In 2 color mode you've got a 640 wide
screen. I 4 color, you've got a 320 wide screen. So the right half of the
image gets truncated.
I may post CSHOW 4.0a if no one has done so yet. It give info as to the
height, width and number of colors of the image and then lets you pick
the display format. I don't even bother trying to display the image
when I get a VGA (I assume) image at 640x400x32 colors... on a CGA the
image won't be viewable.

I've seen this sort of uuencoded file before. I've only had trouble with it
once, and that may have been because the file was garbled. Sounds like you
need a newer uudecode... (I haven't tried to uudecode that file yet, so I may
be back to complain about too!)

I have version 1.5 of the program now. The additional stuff includes support for Hercules mode (no grayscaling) and automatic/manual enlargement/ reduction of the picture to fit screen size which takes care of the problems mentioned. I cannot test the Hercules mode. Seeing as how many people do not like the gif stuff in these newsgroups, I am not going to post it unless there seems to be sufficient demand. If there is, I can send it to the moderator (by the way, how does one send stuff to Rahul ?) Venu P Gopal ihnp4!ihuxy!vg55611

I hope you will post your 1.5 version of vgif. The version I have (don't have the v# here) works reasonably well on most things, but when you use the VGA mode on VGA pictures, it totally hoses the color map. Surrealistic, but not useful. I normally use FASTGIF, and I even took the time to register it. As you describe the new vgif, it would be useful enough to register that, too. Until we get a GIF group... does anyone have any converters for other picture systems? I have seem pictures which were converted from mac, and I think from paintbruch as well. I have some mac pictures (anyone want me to post the CGA and EGA viewers?) and access to a scanjet to make some images which can be made into PCPB (or several other) format. -- bill davidsen (wedu@ge-crd.arpa) {uunet | philabs | seismo}!steinmetz!crdos1!davidsen "Stupidity, like virtue, is its own reward" -me

(I haven't tried to uudecode that file yet, so I may >be back to complain about too!) i received that posting. i couldn't figure out the table keyword so i deleted all of the lines up to 'begin'. then i uudecoded and uploaded to our fountain clone. it un-arc'd just fine ... the .arc file is currently living on one of the compaq's, but if there are enough requests i can uucp it back to this machine. i'll post a message here if and when that happens. the sucker i had the most trouble with was 'fastgif'. it's fast alright, but it hangs the machine on non-existent or corrupted .gif files. grrrr. - john. -- John F.

How did you select a non-existent file from it's menu of what's in the directory?? It doesn't hang on ALL corrupted files, I keep a few beauties around for testing, and it barfed and recovered okay. The thing I like about fastgif is that it will do a credible job of putting VGA/Amiga multicolor images up on an EGA, using dithering. I would love to have an option to change to grey scale, though, since a lot of stuff I have looks better on the Hercules than the EGA or VGA. -- bill davidsen (wedu@ge-crd.arpa) {uunet | philabs | seismo}!steinmetz!crdos1!davidsen "Stupidity, like virtue, is its own reward" -me
