xmag(1X) xmag(1X) 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 se- lect 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. 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 ver- sion of the region in which each pixel in the source image is repre- sented 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 re- gion for this magnification instance. New brings up the rubber band selector to create a new magnification instance. Cut puts the magnifi- cation image into the primary selection. Paste copies the primary se- lection 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 ap- plication. Indentation indicates hierarchical structure. The widget class name is given first, followed by the widget instance name.
