Wish: Speeding up Image zoom

Post by OnO »

Hi,

I wish some stretching improvment. If you don't choose the slow method you got very aliased / blocked images on screen when resizing to fullscreen.
On other hand, slow method is great but it's hell slow.

I'd like to ask you if you use StrechBlt to display images on screen and if you tried to use SetStretchBltMode to HALFTONE, which is not great but quite fast method (Windows internal). This would be nice...
Also you can use hardware for stretching (I'm not sure but it might be true that StretchBlt with HALFTONE mode uses hardware filter).

Regards,
OnO de la Cravovia
