| Hello! Is there anything Imagebuffer like in Bmax? I searched on the forums but I didn't get anything... |
| ||
| Not that I know of, instead: in TPixmap we trust.. |
| ||
| And how would I use that? |
| ||
from the head:local pm:tpixmap=lockimage(yourimage) writepixel pm,x,y,ARGB unlockimage yourimage but check out the manual to be sure. Note that this pixmap thing is all low-level stuff, afaik there's nothing like 'DrawRect', 'Line', 'Oval', etc. Ofcoz, you could do your own line routine using a bresenham algo.. |

| searched on the forums but I didn't get anything... Just need to check. You put 'imagebuffer' or 'imagebuffers' into the Blitzmax forum search and nothing came back? There are quite a few solutions although nothing I would consider 'nice'. Since Indiepath's RTT module isn't working at 1.24 and HighGfx has disappeared for OGL the best solution is either pixmap.paste for no-alpha or memcopy (I have something in the code archive which does it) or draw/grab which is slow. I might look at this again but I'm still gobsmacked that BRL have no interest in providing it. |

| Well I will play with PixelMaps for now... And I exactly searched for "imagebuffer" and only got weird things... |
| ||
| How about OpenGL framebuffer... speaking of which, how do you use that? |
| ||
| There was a render to texture module done by indiepath that would let you mimic it. |

I used this to take a full screengrab, it was very last minute but did what I needed (almost certainly a better 'proper' way though)BackingImage:TImage = CreateImage(800,600) GrabImage BackingImage,0,0 |
