Some improvments...

Hello, Antonio! I worked with some images and catched one idea - simple to code and IMHO quite useful. Here it is: what if to implement to every window with image inside ability to become transparent and unbounded (without frame) ? It could helps to combine (temporarily) images and to adjust them to each other (very fast and roughly).

Thanks!

And it's important for transparent window - to remain available for painting... Will it be useful, what do you think?

[Antonio]

don't understand the use, never needed this function

don't understand the use

It provides an easy way to see how few images will looks together

It's already possible : http://www.photofiltre-studio.com/pf7-en.htm
- in the PhotoFiltre workspace, with layers
- a layer can be saved in png format with it's transparency
