.TH XMAG 1 "xmag 1.0.6" "X Version 11"
.SH NAME
xmag \- magnify parts of the screen
.SH SYNOPSIS
.B xmag
[
.B \-mag
.I magfactor
] [
.B \-source
.I geom
] [
.I \-toolkitoption
\&.\|.\|. ]
.SH DESCRIPTION
The \fIxmag\fP program allows you to magnify portions of an X screen. If no
explicit region is specified, a square with the pointer in the upper left
corner is displayed indicating the area to be enlarged. The area can be
dragged out to the desired size by pressing Button 2. Once a region has
been selected, a window is popped up showing a blown up version of the region
in which each pixel in the source image is represented by a small square of
the same color. Pressing Button1 in the enlargement window
shows the position and RGB value
of the pixel under the pointer until the button is released. Typing ``Q''
or ``^C'' in the enlargement window exits the program. The application has
5 buttons across its top.
\fIClose\fP deletes this particular magnification instance.
\fIReplace\fP brings up the rubber band selector again to select another
region for this magnification instance.
\fINew\fP brings up the rubber band
selector to create a new magnification instance.
\fISelect\fP puts the magnification image into the primary selection.
\fIPaste\fP copies the primary selection buffer into \fIxmag\fP.
Note that you can cut and paste between \fIxmag\fP and the \fIbitmap\fP
program. Resizing \fIxmag\fP resizes the magnification area.
\fIxmag\fP preserves
the colormap, visual, and window depth of the source.
.SH WIDGETS
\fIxmag\fP uses the X Toolkit and the Athena Widget Set.
The magnified image is displayed in the Scale widget.
For more information, see the Athena Widget Set documentation.
Below is the widget structure of the \fIxmag\fP application.
Indentation indicates hierarchical structure. The widget class
name is given first, followed by the widget instance name.
