Bug with Texturemodes?

| Hi together. Take a look at this little sample here. I create a texture with texturemode 1. This works really fine. BUT, if i create the same texture with texturemode 2 or 4 i can not write any text on the texture and the Writepixel Color is wrong, maybe black or something. With other words, if u try to use a texture in mode 2 or 4 it is not possible to write text on this texture. Is this a known Issue? I think it is a BB Problem because i can draw lines, ovals and rects but can not write text or set any point.

| It's a known 'feature'. You shouldn't use Text (and possibly any other drawing commands on textures). Instead render to the BackBuffer and grab. |
| ||
| This works on some hardware and on some it doesn't. So: what Beaker said! Using stringwidth, stringheight and copyrect will make it pretty easy. |
| ||
| The problem is the alpha (transparancy) channel is not being respected by the text command. Try calling this KeyImage function after you have finished drawing to your texturebuffer. |

| wow this is turning out to be a real problem for me... maybe it should be fixed |
