Except, I think you described more how to do it, not so
much what you need to do. :-)
I have an application that generates 4 graphs in .png format; I need
to call "something" from my application to more-or-less simultaneously
display those graphs in 4 individual X-windows as soon as the data
processing is done. All .png graphs are in the local directory where
the app runs.
Do you actually need 4 individual windows, or is that
just one way to display 4 individual graphs at once?
Which is it you want to do?
Xnview is close to what I need, but it only seems to allow one .png to
display at once. I need the 4 .pngs to fill a screen at the same time
to provide the user a comprehensive view of their most recent task.
Any ideas?
Okay, if what you actually need is 4 PNG images
displayed at once, taking up as much of the fill screen
as possible, there are at least two basic ways to do it.
First, you can invoke 4 different instances of just
about any image display program you choose, and get what
you want. As noted by another poster, you'll likely
have to deal with (accepting or getting rid of) borders,
window manager eye candy, possible geometry variations
and positioning problems, and maybe others I'm not
thinking of.
Second, you can use something like the /convert/ program
from ImageMagick to make a single image that contains the
other 4, and then just display that one image with
whatever software you choose.
You can go even farther though, and more or less use a
combination of the above. The display software could
for example be a web browser. Instead of the /convert/
program a shell script can massage and place the 4
images into the right directory for display locally or
remotely via the web browser. (I used to do exactly
that with about a dozen graphs that were generated
originally as a PNG image.)
