2d graphics - can they be scaled ?

[Alien]

ITexture* texture = driver->getTexture("../../media/irrlichtlogoalpha.tga");
env->addImage(texture,core::position2d<s32>(10,10));

Is it possible to change the size of an image using Irrlicht. That is, instead of just displaying the loaded image, you can actually stretch the image so its larger.

I noticed you could lock the texture, and get the pixels...what sort of structure would i use to get the data so i could modify it ?

I'm accessing the texture data in my new fire scene node, you can have a look at it, but basicaly you just have to do this:

Code: Select all

u8* pixels = (u8*) texture->lock();
for (u32 i = 0; i < pixelNum; i++){
    pixels[i * 4] .. //do whatever with the blue component
    pixels[i * 4 + 1] .. //green component
    pixels[i * 4 + 2] .. //red component
    //[i * 4 + 3] could be the alpha value, but I haven't tried it
}

Of course, this just works, when you have the A8R8G8B8 format, but the others should be similar.

Cool Ever played old games like Unreal, and seen how the textures have ripple effects and the pixels undergo filters....this will allow for the same thing But as for scaling textures, this doesn't really help. Is there a way to give a texture a new array of pixels ?
