3023) How do I view pictures on UNIX X-Windows?
For more complete information, you are referred to comp.graphics group
and its FAQ. As far as I know, news on new viewer and image processor
software can also be read in newsgroups such as alt.graphics.pixutils and
alt.binaries.pictures.utilities.
I'd strongly suggest the viewer software 'xv'. Read its manual by
'man xv' for operating instructions. If you don't have access to it,
you have to obtain its source code (src) file from ftp sites and
compile it using the command 'make' in usual cases. (Please also read **)
Example viewer software which support GIF are as follows:
i) xloadimage, xsetbg, xview -
Works on b&w or color displays, see the manual pages to view
the GIF file as a window or to set the image on the
background, it should be available on most sites, otherwise,
src is obtainable via anonymous ftp, export.lcs.mit.edu
[198.112.44.100], /contrib/xloadimage.3.01.tar.Z).
ii) xv - src in
foo.{x,y}.ext means there are 2 files called, foo.x.ext and
foo.y.ext. The newer version (2.11 up) takes both JPEG and TIFF
formats as well. The sites and full pathnames are---
- export.lcs.mit.edu, /contrib/xv-2.{11,21}.tar.Z
- nic.funet.fi [128.214.248.6],
/pub/X11/contrib/xv-2.{20,11}.tar.Z)
- ftp.cis.upenn.edu [130.91.6.8], /pub/xv-2.{11,21}.tar.Z
** Note on how to obtain and compile source code files such as *.tar.Z:
- You can recover the files by working from right to left to
resolve the suffices using the following rules, an example
will follow.
- .Z - Get the src file from ftp site the same way as getting
picture files. When you are in the shell, use uncompress(1)
to restore the .Z compressed files (read compress(1) man page
as well).
- .tar - In the shell, type "tar xvf foo.tar" to extract the
files, the details can be found in the man page for tar(1).
- example - Assuming the file xv2r1.tar.Z is now residing in
the current directory, the steps to be taken are -
a) uncompress xv2r1.tar.Z
You will then get xv2r1.tar at the end after a).
b) tar xvf xv2r1.tar
The source file and subdirectories will be formed, you can
then change its Makefile (see make(1)) to do the compilation.
- If you don't know C and/or makefiles, you better find
someone at where you're at so that they can help you because
you'll need expereince before you can reconfigure the
Makefile and know how to answer the questions for your
system.
