in reply to Tk::Photo and copy method

Tk::Photo supports the following formats:

  • BMP
  • PPM
  • GIF
  • PNG (with extension)
  • JPEG (with extension)
  • TIFF (with extension)

Try using Tk::Pixmap (which supports only XPM) instead.

    Thank for the answer, converter.
    As you see in the code above, my problem relie on the usage
    of the copy method from Tk::Photo.
    Tk::Pixmap has no method which allows partial pixels
    manipulation.
    You can only cget() or configure() the whole.

    But more specifically my question was:
    what's means this "Tk::Photo=HASH(0xc5ef04)"

    I have found the problem.

    An empty photo object must be set without explicit
    descriptor, nor image tags.
    So in the main window, the line:
    my $image = $label ->Photo('image', -height => 10, -width => 10, -format=>'XPM');
    become:
    my $image = $label ->Photo( -height => 10, -width => 10);
    Nice day for you all!
