147.IX Header "DESCRIPTION"
148This is an extension for Tk800.* which will load a Photo image
149from a snapshot of an X window specified by the \-data option.
150.PP
151The window must exist and be visible. Because the code allows
152you to capture windows not owned by Tk it does not attempt to
153enforce this. If you are capturing one of Tk's windows then
154use \f(CW\*(C`$w\->update\*(C'\fR.
155.PP
156If window is mapped, but obscured by other windows then what is captured is the
157rectangle the window would occupy. This can be considered a feature.
158For Tk-owned windows \f(CW\*(C`$w\->raise\*(C'\fR can used to bring window forward.
159.PP
160Once the Photo is loaded it can be saved using
161\&\f(CW\*(C`$image\->write(\-format => ...)\*(C'\fR using any of formats which support
162writing.
