I made a new icon for the trashcan trying to be in line with the OPLC HIG. What do people think ?

Not bad I think - a bit small, though. You must not ever use one- pixel lines, and all the official icons are antialiased. Also, they typically have only one line width throughout.

What display depth is the laptop running ? I noticed that my OPLC image was set to 16 bit color depth. Translucency does not work with images for that depth as far as I know, so there can not be antialias against the background. Or do you know a way to do that ? I can see that text has antialias at 16 bit color depth, so it must be possible... :-) Karl

Ah, you're right, we're running at 16 bpp. Given the high resolution we might get away without AA. Text rendering is a special case ...

Using Form combination rule 34 will allow translucent forms to blend in 8 and 16 bit as well (look at attached screenshot), but there are some not so nice side effect with other forms, (look at the menu icon in the screenshot) :-( Some refactoring or regeneration of the forms in the image is nessesary.

And exporting a 16 bit depth screenshot as png does not work ;-) Here again as bmp.

Here is a change set that make translucency in forms possible for screen depth less than 32. It will use form combination rule 34 if screen depth is less than 32 and the form is of depth 32. It will not work for a rotated form, as I'm not sure yet how to hack FormCanvas transformation methods. But then again translucency does not work with most other rotated morphs either ;-) Can anybody see any other nasty side effects ?
