Gifsicle version 1.51 available (port) (Announce)

Post reply

On 19 May 2008 I finished my 32-bit DOS port of Eddie Kohler's Gifsicle version 1.51 using DJGPP version 2.04 beta. Binaries (gifsicle, gifdiff) and plain text manuals are available as gifs151b.zip. Fully configured sources plus some simple instructions on how to rebuild are in gifs151s.zip.

Changes from 1.49 to 1.51:
* gifsicle: '--crop' preserves the logical screen when it can. Reported by Petio Tonev.
* gifsicle, gifview: Refuse to read GIFs from the terminal. Requested by Robert Riebisch.

This time no DOS or DJGPP specific changes were required.

Concerning file naming problems reported by user DOS386 in GIFSICLE 1.50K uploaded DOS (+Win32) port really works now: You can avoid these problems by running gifsicle -e logo.gif --output=logo. That will produce files named logo.000, logo.001, logo.002, ... So I decided not to provide a patch.

Thanks for your efforts! I'll have to check it out. :-)

BTW, I found another (not really similar) GIF tool called GIFTRANS (w/ src).

Gifsicle 1.52 for DOS will be available tomorrow. ;-) Eddie released a new version today. I'll post a separate announcement then.

Another one is gif4web (source code + DJGPP binary) by Herbert Kleebauer.

Yesterday evening it also didn't work for me, but currently it works.

There is always a hack :clap: confirming that it "works" ... but still:

- Default behavior should be good, not bad
- In DOS (and Win32), GIF images are supposed to carry the file extension ".GIF", not ".000" or so. LXPIC refuses your ".000" or more GIF's.

Thus, it still should be LOGO000.GIF, LOGO001.GIF etc. for DOS ;-)

Some readers look at file headers. Get one that does.

Do you know how to rename files? Maybe you could go as far as writing a patch that goes beyond rr's reasonable port of the existing gifsicle.

Point me to all them, please. Plus, opening all files of a directory just to test whether they are supported is a crappy idea wasting huge amount of performance, it's probably fine on your Vista xxx64, but not in DOS :-P

> Do you know how to rename files?

NO.

I fixed it in my port, maybe I'll release a new version one day. But you don't need GIF support in DOS anyway, you are just trolling. Write the patch yourself ... a chance for your 1st useful post here :-)

Start with ths one: ftp://ftp.sac.sk/sac/graph/lwhiz.zip

1) I don't use Vista at all. 2) DOS runs on fast machines (I mention this because you seem to think DOS requires a 286 or older, with no memory).

DOS docs are easy to find.

I'm waiting.

Why not? And if that's true, what are you fussing about?

> Write the patch yourself ... a chance for your 1st useful post here
NO. I'm not the one with the problem.

It is good enough for me, because it works on LFN-enabled systems and there's a work around for systems with SFN only.

Then LXPIC is stupid. A software should never rely on a file extension. That's why signatures exist in file format specifications.

> Thus, it still should be LOGO000.GIF, LOGO001.GIF etc. for DOS ;-)
I don't think so. But it's open source. So feel free to continue your own port doing "all things better".

Your 2000 Professional (SP4) system :clap:

But that's the (DGJPP-typical) wrong approach ...

Obviously, since LXPIC author didn't make $$$ 50'000'000'000 $$$ with it ...

Your 4-core CPU + SATA-III HD PC has the performance "needed" to comply ...

Good :-) ... but they still don't make extensions obsolete :-P

This is nonsense without a statement of reasons.

Where's the relation?

That's far beyond from my computer's specs.

Sure. File extensions are good for visualization to users.

Did you ever hear about trouble with it, from crosslinking 2 files up to "total" data loss ?

> File extensions are good for visualization to users.
GIF image -> .GIF ... plus for applications allowing them to pick supported files by extensions, without the need of brute-force walking through the directory and opening all files :-P

PS: reportedly some "OS'es" (not applications :lol3:) do exist not only pre-opening all files for the purpose of checking the signature, but also reading and decoding all data of all files for creating previews ... just in case you find out to be in the wrong directory anyway :-D

Not always useful, on account of the many GIF formats. A viewer can save work by checking headers before trying to open what it actually doesn't know how to.

What OSes? All files on disk, regardless of disk size?

WRONG - it must open the file before it can read the header at all :lol3:

> What OSes?

Check your PC's :hungry:

In directory.

He's probably talking about "Thumbnail View" on Windows.
