Hello! I did not see (or perhaps I overlooked) a simple graphics image viewer applet in TC base or in the TCE/TCZ appbrowser, so I coded up one in FLTK.
This program's executable is tiny (> 6K!
) and loads images really fast. It supports:
* .JPG / JPEG
* .GIF
* .PNG
* .BMP
* .XBM
* .XPM
It can be also launced from the command line. Assuming it is placed in /usr/local/bin, or some other place in the search path, simply invoke:
# fl_picsee {{filename, which may include path}}
It works well with Rox-Filer if you set the run action to launch it. In Rox, right-click, select "Set Run Action...", then put something like the following in the "Enter a shell command" text field:
/usr/local/bin/fl_picsee "$@"Downsides? It does not support scrolling and will not resize the image if it is too big to see on your screen. The full path and file name in the title will be clipped if the window title bar is not long enough (especially true for small images), and the window maximizing button does not really work. As I learn more about FLTK, I will try to address these shortcomings.
This 0.8.0 version is an alpha release only. I have not learned fully how to make a .tce or .tcz distribution, so I am posting the GPL source code. Perhaps Jason can package it for me once until I learn how to do it myself. Or if given permission, I can attach the binary directly.
This requires the 1.1 version of FLTK, which is standard in TC 1.3 (and earlier, I assume).
Please address bug reports and and comments to this thread. Hope you like it!
Source Code (EDIT, updated to version 0.8.1, which has some modifications to handle filenames that are too short or too long):
// fl_picsee -- A FLTK-based picture viewer
#define appver "0.8.1"
