Enable Dithering...

| is here a function to enable dithering in blitzmax? how can i do this? |
| ||
| On the DX Side, this should enable it: primarydevice.GetDevice(_max2ddriver).SetRenderState D3DRS_DITHERENABLE,True |
| ||
| shouldn't this be enabled by default in dx? a minor bug perhaps ? |
| ||
| In OpenGL it is glEnable(GL_DITHER) or glDisable(GL_DITHER) It only dithers in 16bit or 8bit modes. Ie, if you open a 16-bit screen or if you open a desktop window and your desktop is at 16-bit or 256 colors. You can still draw everything using 32-bit images, but it will dither down to the output. |
| ||
| support all gfx cards hardware dithering? |
| ||
| yes all cards support it - it was in Blitz3D and I moaned back then in beta about having it switched on too :) |
| ||
| dithering can actually look worse with "true colour" modes |
| ||
| I thought dithering wasn't on in true colour modes? It should not be enabled in 32bit. |
| ||
| Here I've only seen dithering in 16-bit high/true-color or 8-bit index modes, not 32-bit. The whole point of dithering is it dithers down from 32-bit to whatever the color depth is, so it wouldn't make sense to apply it to truecolor 32-bit if the screen is 32-bit also. I've also found that at least on my system a 16-bit screen with dithering is not any faster than a full 32-bit screen. |

| Todays card work internally on 32bit anyway ... most card that would have a use for dithering are cards that most likely will have performance problems with BMs 3D only rendering as well ... |
