6 ida - image viewing and editing program

9 ida [options] file ...
10
12 Ida is a small and fast application for viewing images. Some basic
13 editing functions are available too.
14 You can specify any number of image files as arguments on the command
16 line. Or you can read a single image from stdin by specifying "-" as
17 only argument ("xwd | ida -" works nice for screenshots).
18
20 Ida understands the usual toolkit options (-geometry + friends). Addi‐
21 tional options are:
22 -help print a short help text
24 -pcd n Pick size for PhotoCD images (n = 1 .. 5, default 3).
26 -debug Enable debug messages. Also has the side effect that error mes‐
28 sages are displayed on stderr only and not as message box.

31 Mouse functions
32 With the left mouse button you can creates and edit a selection rectan‐
33 gle. The middle button is used to start drag'n'drop operations. The
34 right button brings up the control window with menus, toolbar and file
35 list.
36 Keyboard Shortcuts
38 Many keyboard shortcuts used by xv are available in ida too. If you are
39 familiar with xv if should be easy for you to get started with ida.
40 All available keyboard shortcuts are also listed in the menus of the
42 control window. The most important ones are listed below:
43 SPACE Next file.
45 BACKSPACE
47 Previous file.
48 LEFT_ARROW, RIGHT_ARROW, UP_ARROW, DOWN_ARROW
50 Scrolling (hold Ctrl key for big steps).
51 +/- Zoom in/out.
53 q Quit.
55 Supported image formats
57 Read: BMP (uncompressed), PhotoCD, PPM, XBM, XPM, XWD, GIF, JPEG, PNG,
58 TIFF. The last four are supported using the usual libraries,
59 i.e. you need to have them installed at compile time.
60 Write: JPEG, PNG, PostScript, PPM, TIFF.
62 Using drag'n'drop
64 Ida is a motif application and thus supports the motif drag'n'drop pro‐
65 tocol in both directions. The xdnd protocol is supported too, but only
66 in one direction (receive drops).
67 Ida uses the middle mouse button to start a drag'n'drop operation (as
69 the motif style guide suggests). This works for the main window and the
70 file buttons within the file browser.
71 Motif applications should have absolutely no problems to deal with
73 ida's drag'n'drop support. You can drop images into some netscape 4.x
74 window -- it imply works. Mozilla accepts motif drops too.
75 Interoperation with gnome / gtk is good. I can drag files from ida to
77 eeyes and visa versa without problems. File drops from gmc into ida
78 work just fine too.
79 Interoperation with KDE is bad. cut+paste works most of the time,
81 drag'n'drop often doesn't. The X11 selection handling of the Qt toolkit
82 has a few design bugs and sucks. Basically the troll guys didn't under‐
83 stand what the TARGETS target is good for and violate the ICCCM specs
84 by ignoring it.
