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 imagefile
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.
The "
–dev
" option specifies the graphics device, but is not
needed with most versions of the software. If it is needed,
simply provide the path to the graphics device with that option.
