Rotation with alpha surfaces

PostPosted: Aug 4, 2006 @ 9:15pm

Hello,

the current PocketFrog rasterizer supports blitting with an alpha surface. Unfortunately all more advanced blit functions like BlitRotated(), BlitStretch() etc. don't consider the additional usage of alpha channels. So after checking the PocketHAL 0.8 ALPHA thread some question came up to me:

1. The most important one: Will development of PocketHAL still be continued? Last post in the PocketHAL 0.8 Alpha thread didn't sound promising.

2. If yes, can we expect that the mentioned functions will be implemented?

3. If answer to 3 is no: What would be a good way of implementing it (and considering performance) by my own?

Greetings and thanks in advance,
Chris

Hi. I found a trouble with your code. When I draw surface below display (surface y > 320 - surface height), my game crashes. Also when I draw surface above display (surface y < 0 - surface height), it appears in y=0 !!

A have no idea what kind of trouble is this. Maybe it's trouble with my code, but i'm not shure. Is there anybody who met this trouble? And how can i solve it?
