I posted this on the other forum but having heard it was due to go down the S bend soon I'm posting it here so you won't miss it.I've constructed a GUI for the Untiff dos file but everytime I select a file in a list and try to process it I end up with a 1kb sized tif as the output.
In a dos window it works as it should: untiff input.tif output.tif but in my util it quickly brings up a dos window, runs the untiff with variables set for the input and output filename but then the output is knackered.
Basically the filename is being passed when a user selects it from a file list box to a variable and this becomes both input and output in a winexec string.
I know the filename string is correct because it processes the command and the output is the same name, what have I missed here?

I may not be reading you right but maybe the problem has something to do with using the same name for the input and output. I can't see why this would be a problem anyway but who knows.If you wanted to get really fancy you could get the libtiff librarys and do a really flexible converter. IP: Logged |

I tried it using the same variable as input and output, which I thought should work as the output name needs to be the same name.
I'll try a different variable for the same name and see what happens.
All I need is to make the converter user friendly for the Untiff command, I wasn't planning on any other features as the main thing was to get the tif into some of the big paint programmes that don't open compressed tifs. I heard Photoshop or was it Paintshop(?), won't load in these Sdoe tifs?
Thanks Bryan.
Cheers

Tried changing variables and no luck.
I'll shove it in the todo bin for a while I think.
Getting Sdoe 1.4 tweaked up again anyhow.

Sorry for the delay Spyder, I was looking for the source to untiff.
Unfortunately it was something I literally hacked together in an hours time and the source seems to have gone *poof*I'm updating our geometry builder so that the source has all the proper copyrights (so I can put it on the site) and I'll include a new untiff with source at the same time.

Spyder,there is a free image viewer called Irfanview that can do untiff's job, and that can also save tiffs in compressed format.

Hey no probs MH and Royohboy. Actually the untiff.exe is fine, I'm just having difficulty making it run in a window correctly.
I'll try the other one you mentioned and see how it goes.

That util is very nice Royohboy but the steps to opening a compressed tif then saving it uncompressed take time.
My util just has you select the tif in a window and convert it taking two steps.
MH is the untiff utility under control of the unisys guys or is that just for using tif pictures on a page or utility?

IMHO the batch-conversions are what makes Iview powerful. A dedicated tool like yours, however, has its own advantages. I didn't want to denounce your program.Happy coding, Peter IP: Logged |

Hey no worries, that Irfanview util is a great piece, far better than my effort but it's just a little too much for those wanting a simple click and convert util.
It's just something to help with the SDOE tifs not a graphics package, no need to reinvent the wheel with utils such as Acdsee and the like doing taking care of that.
What I've done so far is basically a miniature explorer window showing directories on the left and files on the right, so you just browse to your tif file or files, select it and click Untiff.
Here's a piccy.

Spyder,I think your GUI is just fine. Adding a batch command while nice, but really the only benefit to that would be for those working on terrain. All other tif groups arnt that large, so I dont think you should go gray trying to make batch functions. I already have all the terrian untiffed, so yes it would have been nice, there again more people I think would only be untiffing a few items at a time. What I really want is a Untiff Plug-in for Photo Shop, I can dream ant I? What am I trying to say? Hmm not much I guess  Carry on, I'm sure you'll do a fine job. ------------------

One question BTW,what is the compression needed for? Does it have any favourable effect if user compress e.g. their home-made airfield or town textures? Peter IP: Logged |

I think the compression only serves to keep the parfiles smaller than they are.
The slow loading screen is due to these files being uncompressed I think.
You don't need to compress your tifs back in order for them to be used, it's just some paint programmes don't recognise or load compressed tifs at the moment and prevents you from painting them.
Zoy found photshop doesn't load these in, yet Acdsee does it.

The SDOE Tiffs use gzip compression which is why some packages don't load them. It seems strange that something like paint shop pro doesn't support gzip, as the libtiff stuff has all of this, is free and extremly easy to use (I even got it work!) It would be nice if a converter converted from the gzip stuff to one of the compressions supported by paint packages, e.g. LZW or something like that to keep the file sizes down, I believe that SDOE does support other compression types. Maybe an idea for your new untiff MH? The reason the load screen takes a while when it first loads a terrin is because it is optimising the textures for a particular vid card. For example the 3dfx stuff likes 16 bit textures while some of the other stuff likes 32 bit. IP: Logged |

We're actually using ZLib and libtiff in Fighter Squadron.We use the compression both to keep the file size small and so that the textures load faster. We went with zlib rather than lzw so that we wouldn't have to pay the vampires at Unisys for every copy of FS that was sold. FYI, libtiff is currently maintained at: http://www.libtiff.org/
and zlib can be found: ftp://ftp.cdrom.com/pub/infozip/zlib/zlib.html IP: Logged |

Spyder...I've created a new utility (actually it's a build of a util that comes with libtiff) go to: ftp://lynx.inertiagames.com/pub/openplane/tiffcp.zip and you'll find a util that will uncompress and compress tiffs. The source is part of libtiff. IP: Logged |

Thanks MH, grabbed it.
This will be more functional, now I can compress them back too.

Oops! yeah I got side tracked on the other util. I figured the skin changer had more priority and represented a challenge.
Will get back to this shortly.
