Q: I have several .gif files I wish to display in rapid succession
under X ...
One answer: get the Utah Raster Toolkit, convert the .gif files to
.rle (URT file format), and use getx11 -m to display them as a movie.
Of course, this may be high overhead if you only want to do this once.
The files currently included in the Utah Raster Toolkit distribution are:
urt-3.0.tar.Z Toolkit source and manual pages. (700K, 1900K uncompressed)
urt-doc.tar "Papers" describing the toolkit. (550K)
urt-img.tar Sample images. (1800K)
urt-3.0.patch1 The first patch file. Must be applied to the 3.0 distribution.
urt-3.0.patch2.Z The second patch file. Must be applied after
urt-3.0.patch1.
The only files you need to build the toolkit are the first, plus any
patches that apply to it. The first file is a compressed tar file.
The next two are ordinary tar files because they compress only 5-10%,
so it isn't really worth the CPU time. The patch files are either
normal text files or compressed text files, depending on their size.
You must use FTP's BINARY mode to properly copy the distribution. To
unpack it, you can follow the following steps:
cd (appropriate source directory)
mkdir urt
cd urt
zcat urt-3.0.tar.Z | tar xfo -
tar xfo urt-doc.tar
tar xfo urt-img.tar
patch -p -N <urt-3.0.patch1
zcat urt-3.0.patch2.Z | patch -p -N
The 'o' option to tar makes sure you own the resulting files under
Sys V, and appears to be harmless on other systems.
If you don't have the patch program, you can install the patches by
hand, but it might be easier to get patch (it is present in many
source archives around the world, including the comp.sources.unix
archives).
Assuming the patches are applied successfully, you will want to remove
the ".orig" files that patch creates:
find . -name '*.orig' -print -exec rm -f {} \;
Note: zcat is a form of the "compress" utility. It decompresses the
file named and writes the result to the standard output. If you don't
have zcat (although, if you have compress, you ought to have zcat),
you can
compress -d urt-3.0.tar.Z
tar xfo urt-3.0.tar
tar xfo urt-doc.tar
tar xfo urt-img.tar
patch -p -N <urt-3.0.patch1
compress -d urt-3.0.patch2
patch -p -N <urt-3.0.patch2
If necessary, we may be able to supply other file formats (e.g., cpio
or shar).
