| 20 | ||
| 21 | Tk::WinPhoto - Load a Photo image from a window | |
| 22 | ||
| 23 | =for category Experimental Modules | |
| 24 | ||
| 25 | =head1 SYNOPSIS | |
| 26 | ||
| 27 | use Tk; | |
| 28 | use Tk::WinPhoto; | |
| 29 | ||
| 30 | my $image = $mw->Photo(-format => 'Window', -data => oct($mw->id)); | |
| 31 | $image->write($path_name, -format => 'BMP|PPM|XPM'); | |
| 32 | ||
| 33 | ||
| 34 | =head1 DESCRIPTION | |
| 35 | ||
| 36 | This is an extension for Tk800.* which will load a Photo image | |
| 37 | from a snapshot of an X window specified by the -data option. | |
| 38 | ||
| 39 | The window must exist and be visible. Because the code allows | |
| 40 | you to capture windows not owned by Tk it does not attempt to | |
| 41 | enforce this. If you are capturing one of Tk's windows then | |
| 42 | use C<$w-E<gt>update>. | |
| 43 | ||
| 44 | If window is mapped, but obscured by other windows then what is captured is the | |
| 45 | rectangle the window would occupy. This can be considered a feature. | |
| 46 | For Tk-owned windows C<$w-E<gt>raise> can used to bring window forward. | |
| 47 | ||
| 48 | Once the Photo is loaded it can be saved using | |
| 49 | C<$image-E<gt>write(-format =E<gt> ...)> using any of formats which support | |
| 50 | writing. | |
