NAME

6       Tk::WinPhoto - Load a Photo image from a window
7

SYNOPSIS

9         use Tk;
10         use Tk::WinPhoto;
11
12         my $image = $mw->Photo(-format => 'Window', -data => oct($mw->id));
13         $image->write($path_name, -format => 'BMP⎪PPM⎪XPM');

DESCRIPTION

16       This is an extension for Tk800.* which will load a Photo image from a
17       snapshot of an X window specified by the -data option.
18
19       The window must exist and be visible. Because the code allows you to
20       capture windows not owned by Tk it does not attempt to enforce this. If
21       you are capturing one of Tk's windows then use "$w->update".
22
23       If window is mapped, but obscured by other windows then what is cap‐
24       tured is the rectangle the window would occupy. This can be considered
25       a feature.  For Tk-owned windows "$w->raise" can used to bring window
26       forward.
27
28       Once the Photo is loaded it can be saved using "$image->write(-format
29       => ...)" using any of formats which support writing.
