Hi 24k911, welcome to the forum.  There is an OpenGL command called glReadPixels but sadly it isn't implemented in Basic4GL.  There might be an example of pixel reading somewhere on the forum somewhere, I'll try & look if there is one. You might want to try the ToolBox plugin by djlinux, I believe it contains a command for reading pixels. If you need to know how to install plugins, look at this post. |

Once you've downloaded the plugin from here, you'll find an example file called getpixels.gb in the folder. |

Hmm, I haven't used the plugin that much, so I'm not sure what could be wrong? You should make a post in the ToolBox dll thread, maybe djlinux will see it & he'll be able to help you more. |
