Images are real objects; we need to create them and, when we're finished, destroy them; otherwise, their resources remain in use for the duration of program execution. For instance, if we create an image and assign it to a Label, then at some later time destroy the Label, like so:
my $l = $mw->Label(-image -> $image) ... $l->destroy;
the image remains alive and ready for use again and again, even by multiple widgets simultaneously. If we want the image to go away, we must explicitly delete it:
$image->delete;
This applies to Bitmap, Pixmap, and Photo image types. Here are other methods available for any image type:
