- <P>This is an extension for Tk800.* which will load a Photo image
- from a snapshot of an X window specified by the -data option.</P>
- <P>The window must exist and be visible. Because the code allows
- you to capture windows not owned by Tk it does not attempt to
- enforce this. If you are capturing one of Tk's windows then
- use <CODE>$w->update</CODE>.</P>
- <P>If window is mapped, but obscured by other windows then what is captured is the
- rectangle the window would occupy. This can be considered a feature.
- For Tk-owned windows <CODE>$w->raise</CODE> can used to bring window forward.</P>
- <P>Once the Photo is loaded it can be saved using
- <A HREF="../../../lib/Pod/perlfunc.html#item_write"><CODE>$image->write(-format => ...)</CODE></A> using any of formats which support
- writing.</P>
