NAME
xmag - magnify parts of the screen
SYNOPSIS
xmag [-mag magfactor] [-source geom] [-toolkitoption...]
OPTIONS
This option specifies the size and/or location of the source region on the screen. By default, a 64x64 square is provided for the user to
select an area of the screen. This option indicates the magnification to be used. 5 is the default.
DESCRIPTION
The xmag program allows you to magnify portions of an X screen. The magnification occurs on the screen specified by the $DISPLAY environ-
mental variable or by the -display command line option regardless of location of the mouse pointer in a multi-screen display. 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. Close deletes this particular magnification instance.
Replace brings up the rubber band selector again to select another region for this magnification instance. New brings up the rubber band
selector to create a new magnification instance. Cut puts the magnification image into the primary selection. Paste copies the primary
selection buffer into xmag. Note that you can cut and paste between xmag and the bitmap program. Resizing xmag resizes the magnification
area. xmag preserves the colormap, visual, and window depth of the source.
WIDGETS
xmag 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 xmag application. Indentation indicates hierarchical structure. The
widget class name is given first, followed by the widget instance name.
