| 01:32 | vitelmussi | hola quien por aqui |
| 13:55 | wumpus | _rmk_: yes, the stretch blit is pretty useless, it doesn't support any filtering, the filter blit does but it doesn't support clipping |
| 13:57 | wumpus | I was first assuming stretch would do some kind of interpolation, so I tried to draw gradients using it, but just got huge pixels :-) |
| 13:59 | wumpus | the filter blit is pretty neat though, apart from that it needs two passes |
| 15:31 | jnettlet | I assume you guys are using either gco2D_SetStretchFactors, or gco2D_SetStretchRectFactors first. |
| 15:41 | wumpus | yes |
| 15:42 | wumpus | I compute the stretch factors according to ((src_width - 1) << 16) / (dst_width - 1) and vice versa for height, as it says in the docs |
| 15:43 | jnettlet | and the destination surface has a format that supports Alpha blending. |
| 15:44 | wumpus | yes, simply A8R8G8B8 |
| 15:44 | wumpus | is it supposed to do a smooth scaling then? |
| 15:50 | jnettlet | nope. If you have a yuv format or need smoothscale then you have to do a filterblit |
| 15:51 | jnettlet | yuv src format that is |
| 15:51 | wumpus | ok, yes that's what I thought |
| 15:59 | jnettlet | and you can also set the scaling quality to use. |
| 16:01 | _rmk_ | err, why does the destination need to support alpha blending, that sounds soo obtuse. |
| 16:01 | _rmk_ | and where does the alpha come from with a yuv source... |
| 16:02 | jnettlet | if you have a yuv source then you can only use a filterblit, in which case you can have a non-alpha destination |
| 16:03 | jnettlet | the alpha blending destination is a limit on the stretch blit |
| 16:06 | jnettlet | I believe it has to do with the limitation of only being able to have either the ROP or alpha blending engine on for an operation |
| 16:26 | dbsx | I found the spi flash bug in 3.11! |
| 16:28 | wumpus | woohoo |
| 16:28 | dbsx | It took a while |
| 16:28 | dbsx | sleep now |
| 16:31 | _rmk_ | congrats |
| 16:36 | dbsx | Not sure how to fix it |
| 16:37 | dbsx | ttfn |
| 20:25 | dv_ | jnettlet_: you ran the vmeta tests on the XO-4, and saw the flickering, do I remember this correctly? |
