Getting a TGLImageFrame from a TImage

| I'm trying to get the handle of a TglImageFrame from a loaded image. The image is definitely loaded ( verified in that I can draw with it and it returns it's width correctly ) and I'm using the GL drivers with SetGraphicsDriver GLMax2DDriver() However, the frame is always null. Just not sure what else I need to do before retrieving the imageframe. Local frm:TGLImageFrame frm=TGLImageFrame(Image.frames[0]) If Frm=Null Then RuntimeError "NO FRAME" It errors with "NO FRAME" every time. |

| Hello. Should it be frames[1]? Or perhaps you need to cast after your 'frm='? Goodbye. |

| Are you sure that you are in OpenGL and not D3D? :) |

| Should it be frames[1]? Nope, it throws an error for trying to go beyond the bounds of the array if I go beyond 0. Or perhaps you need to cast after your 'frm='? I tried cutting out casting altogether and just going for the ImageFrame base class. Local TFrame:TImageFrame TFrame=Image.frames[0] TFrame is also Null. Are you sure that you are in OpenGL and not D3D? :) Well I'm sure I have SetGraphicsDriver GLMax2DDriver() at the beginning of my code and I'm sure I don't called SetGraphicsDriver ever again, so I'm pretty sure. By not casting to the GL-specific version, and still getting a null TImageFrame, that would appear to indicate that it's another problem. I'm baffled though. |

| strange ... as I know that it works if you use image.frame[0] to modify u0,v0,u1,v1, as I was in need to use that for an energy bar ... will have a look after I got some sleep ... looks somehow quite strange ... |
