Thank you for your reply.
There is a reason I'm trying to make Image::Base load the jpeg and not Gtk2.
Displaying several thumbnails on a canvas is very slow with the image loading abilities of Gtk2.
Image::Base has GTk2 parts and Imlib2 parts, so I thought they would offer some kind of connection between them.

Perhaps it would be better to just use the Imlib2-module with the Gtk-module?
I don't know. The Image::Base part may be unnecessary or even a bad idea.

    I thought about it for a while and realized it would be a good idea to find out where the time is lost during the display of the images as thumbnails.
    I used Time::HiRes to find out.

    I am actually loading jpeg data from a tar archive. I have to convert this to a Pixpuf, because Gtk2-Canvas needs a pixbuf to show the data.
    The conversion function into a pixbuf consumes the majority (~70%) of the time.

    This may be a hint that this won't be faster using Imlib2?
