colormap is used for the image display window. If this option is

not provided, the default colormap is used.

The utility has two basic modes of operation:

• window capture

• region capture

To capture the contents of a particular window, run tsiwd

without the geometry argument. The cursor will change shape to

resemble a cross, at which point the user can left-click on the

window that is selected for capture. Selecting the root window in

this manner will capture the entire screen's contents.

Alternatively, specifying the region’s geometry with the geometry

option can capture an exact region of the screen.

For example:

prompt% tsiwd –geometry 0,0,100,150 –imgfile

filename

The "x" and "y" specify the upper left-hand corner of the region,

which, along with "width" and "height", describes the rectangular

area to capture.

When the captured image is saved by default, the image file is in

PNG format. The PNG format provides lossless compression,

24-bit color, and may be viewed with a variety of common

imaging applications. The image can also be saved as BMP or

PPM by using the –bmp or –ppm options on the command line.
