 It is not as faster as a viewer, but it is better than other solutions.

guash is quite nice. it mimics xv's visual schnauzer (the best image
browsing interface, if you ask me ;) and it very useful in the cited
problem of perusing multiple xcf files that are different versions of the
same image.

Re: IrfanView

2000-05-30 Thread Guillermo S. Romero / Familia Romero

By default photoshop saves a flattened version of the image as well as all of
the layers for backward compatibility purposes.  I would assume that
IrfanView is
just displaying the flattened version of the image straight from the file.

We may want to add similar functionality to gimp and the xcf format at some
point
to make it easier for other applications to display xcf files.

No no no, or optional. I got a .psd and it was big (now I know why). I
loaded into Gimp, saved and compressed and it become small (it had two
layers, plus the copy, after only two real ones and bzip2'ed).

So the "full copy in one layer" should be optional, like GIF comments or
similar things. I do not want to waste disk space just cos others want to
view .xcf (what I always take as the source file of image works, a .c file
for images, not the binary, the final image).

And btw, to quick load, have anyone tried "gimp --no-data --no-splash file"?

It seems to me like we should provide a libxcf for applications such as this.

Better.

Hi,

   Wouldn't it be good for Gimp, if there would be an external viewer
   to watch the files?

 Yes and no. He told me that he wouldn't be making the viewer able to
 parse xcf files completely, anyway, as that would be too complex. Only
 the bottom layer would probably be shown. (This is how IrfanView works
 for psd (Photoshop) files, too, I think.)

I think, that's a misunderstanding. It seemd very strange to me, that such a
complex viewer shows only the bottom layer of an image file, so I tried
IrfanView with layerd Photoshop-files:
it shows the layers flattened on a white background, that means, the
transparency  of the bottom-layer doesn't work with pds-files, but beside
this, everything is visible, not just the bottom-layer.
The layers aren't available in the viewer, but that's not, what a viewer is
asked for.

 And as the only reasonable
 reason to use xcf format in the first place is when you are working on
 some multi-layer or otherwise complex image in the GIMP and want to
 save it between editing sessions, wouldn't it be counter-productive if
 IrfanView would show only the bottom layer?

Yes, but like I said before: I think that's a misunderstanding. Somehow it
would be a little bit ridiculous to show only the bottom layer.

 Xcf is not intended to be an image distribution format, or an image
 interchange format between applications. I don's see why anybody would
 distribute xcf images except if they are 100% sure that the
 recipient(s) are going to work on them with the (same version of)
 GIMP.

If I'm working on a grafical project, after a while I have often 20 or 30
quite similar xcf-files - every one an other version of the same thing. If I
now try to find any detail that I did before, I have to open all the files
with gimp. Thumbnails don't help here.
A quick viewer would be very nice.

Huh? The GIMP sources are easy to find. The only documentation for the
xcf format *is* the source code in xcf.c and other files.

  It's a pity. What's going wrong, that it ends up like this?

Actually, there is a document describing the format in the docs/
directory of the source tree.  It might not be perfectly up to date, but
I suspect its fairly close.

No, you store all niftiness such as paths, etc.  Though if you can't
view the layers, its not as cool/useful.  From a work standpoint, it
only makes sense though - you'd have to implement every
layer/mask/channel/etc mode and behavior to properly see files.

 interchange format between applications. I don's see why anybody would

I'll agree with this.  But it'd be nice to be able to let image
cataloging programs at least get a reasonable thumbnail; something to
discuss for future xcf formats I suppose...
