NAME

xmag - magnify parts of the screen

SYNOPSIS

xmag [ -mag magfactor ] [ -source geom ] [ -toolkitoption ... ]

DESCRIPTION

The _x_m_a_g 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. _C_l_o_s_e deletes this particular magnification instance. _R_e_p_l_a_c_e brings up the rubber band selector again to select another region for this magnification instance. _N_e_w brings up the rubber band selector to create a new magnification instance. _S_e_l_e_c_t puts the magnification image into the primary selection. _P_a_s_t_e copies the primary selection buffer into _x_m_a_g. Note that you can cut and paste between _x_m_a_g and the _b_i_t_m_a_p program. Resizing _x_m_a_g resizes the magnification area. _x_m_a_g preserves the colormap, visual, and window depth of the source.

WIDGETS

_x_m_a_g 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 _x_m_a_g application. Indentation indicates hierarchical structure. The widget class name is given first, followed by the widget instance name.
