Does Win32::GUI provide any means of capturing a specified rectangular

Search the Win32 API for "Capturing an Image", then do your stuff with
Win32::API. Then turn it into a module and make the world a happier place,
not to mention making Perl a more capable language :)
The keywords are: CreateCompatibleBitmap, CreateCompatibleDC and BitBlt. A
short quote from the API docs:
"You can use a bitmap to capture an image, and you can store the captured
image in memory, display it at a different location in your application's
window, or display it in another window.
...
To store an image temporarily, your application must call
CreateCompatibleDC to create a DC that is compatible with the current
window DC. After you create a compatible DC, you create a bitmap with the
appropriate dimensions by calling the CreateCompatibleBitmap function and
then select it into this device context by calling the SelectObject function.
After the compatible device context is created and the appropriate bitmap
has been selected into it, you can capture the image. The Win32 API
provides the BitBlt function to capture images."
