ITexture -> IImage & IImage -> ITexture
Posted: Wed Jun 13, 2007 9:53 am
Here are two functions to convert an IImage into an ITexture and viceversa. Remember to ALWAYS drop the returned pointer. I've made it for a class to manipulate a texture\image.
For example with these functions you can serialize an ITexture to a file. Simply convert it to an IImage and call video::IVideoDriver::writeImageToFile
Hope that they helps

Code: Select all
video::ITexture* texture = driver->getTexture("rigell.bmp");
video::IImage* image = TextureImage(texture);
[.......]
image->drop();

video::IImage* image = driver->createImageFromFile("rigell.bmp");

texture->drop();
Code: Select all
//Convert a texture to an image. Remember to drop the returned pointer
video::IImage* TextureImage(video::ITexture* texture);
//Convert an image to a texture. Remember to drop the returned pointer
video::ITexture* ImageTexture(video::IImage* image, core::stringc name=core::stringc(""));
Code: Select all
video::IImage* raf::conv::TextureImage(video::ITexture* texture) {
video::IImage* image = driver->createImageFromData (
texture->getColorFormat(),
texture->getSize(),
texture->lock(),
false //copy mem
);
texture->unlock();
return image;
}
video::ITexture* raf::conv::ImageTexture(video::IImage* image, core::stringc name) {
video::ITexture* texture = driver->addTexture(name.c_str(),image);
texture->grab();
return texture;
