.SH NAME
ida - image viewing and editing program
\#

.SH SYNOPSIS
\fBida\fP [\fIoptions\fP] \fIfile ...\fP
\#
\#
.SH DESCRIPTION
.BR Ida
is a small and fast application for viewing images. Some basic editing functions
are available too.
.P
You can specify any number of image files as arguments on the command line. Or
you can read a single image from stdin by specifying "-" as only argument ("\fIxwd
| ida -\fP" works nice for screenshots).
\#
\#
.SH OPTIONS
.BR Ida
understands the usual toolkit options (-geometry + friends). Additional options
are:
.TP
.B -help
print a short help text
.TP
.BI "-pcd" "\ n"
Pick size for PhotoCD images (\fIn = 1 .. 5\fP, default 3).
.TP
.B -debug
Enable debug messages. Also has the side effect that error messages are
displayed on stderr only and \fBnot\fP as message box.

.SH "GETTING STARTED"
.SS Mouse functions
.P
With the left mouse button you can creates and edit a selection rectangle. The
middle button is used to start drag'n'drop operations. The right button brings
up the control window with menus, toolbar and file list.
.SS Keyboard Shortcuts
.P
Many keyboard shortcuts used by
.BR xv
are available in
.BR ida
too. If you are familiar
with
.BR xv
if should be easy for you to get started with
.BR "ida" "."
.P
All available keyboard shortcuts are also listed in the menus of the control
window. The most important ones are listed below:
.TP
\fBSPACE\fP
Next file.
.TP
\fBBACKSPACE\fP
Previous file.
.TP
\fBLEFT_ARROW\fP, \fBRIGHT_ARROW\fP, \fBUP_ARROW\fP, \fBDOWN_ARROW\fP
Scrolling (hold \fBCtrl\fP key for big steps).
.TP
\fB+/-\fP
Zoom in/out.
.TP
\fBq\fP
Quit.
.SS Supported image formats
.TP
.B Read:
\fIBMP\fP (uncompressed), \fIPhotoCD\fP, \fIPPM\fP, \fIXBM\fP, \fIXPM\fP,
\fIXWD\fP, \fIGIF\fP, \fIJPEG\fP, \fIPNG\fP, \fITIFF\fP. The last four are
supported using the usual libraries, i.e. you need to have them installed at
compile time.
.TP
.B Write:
\fIJPEG\fP, \fIPNG\fP, \fIPostScript\fP, \fIPPM\fP, \fITIFF\fP.
.SS Using drag'n'drop
.B Ida
is a motif application and thus supports the motif drag'n'drop protocol in both
directions. The \fBxdnd\fP protocol is supported too, but only in one direction
(receive drops).
.P
.BR Ida
uses the middle mouse button to start a drag'n'drop operation (as the motif
style guide suggests). This works for the main window and the file buttons
within the file browser.
.P
.B Motif applications
should have absolutely no problems to deal with
.BR "ida" "'s"
drag'n'drop support. You can drop images into some netscape 4.x window -- it
imply works. Mozilla accepts motif drops too.
.P
Interoperation with 
.B gnome / gtk
is good. I can drag files from
.BR ida
to
.BR eeyes
and visa versa without problems. File drops from
.BR gmc
into
.BR ida
work just fine too.
.P
Interoperation with
.B KDE
is bad. cut+paste works most of the time, drag'n'drop often doesn't. The X11
selection handling of the Qt toolkit has a few design bugs and sucks. Basically
the troll guys didn't understand what the TARGETS target is good for and violate
the ICCCM specs by ignoring it.
