sf::Image and OpenGL textures
« on: October 14, 2011, 09:42:02 pm »
I am not sure about this, but from the looks of it, SFML1.6 I don't see anyway to have sf::Image just load a image file and not create a OpenGL texture? I just want to use sf::Image to load the data, and allow me to use the pixel pointer to upload the data to OpenGL so I can create the kind of texture format I would like to use. e.g. mipmapped, compressed ect...

As of now I allow it to go through the whole process and delete itself, but seems like a huge waste of time, and OpenGL has to load/unload a texture right away....

Thanks

No, in SFML 1, this is not possible.

SFML 2 introduced the separation between sf::Image (pixel data) and sf::Texture (OpenGL texture).

Thanks Nexus. I will keep this in mind and upgrade to SFML 2.0 when it's out then. Sigh the wait continues....

You can already upgrade now and download the current revision from GitHub. Many people use the development version of SFML 2.

I use SFML 2.0 in commercial products. It's fine as it is now :)

Yup, and it's the best way to make SFML-2.0-RC better ;p
