How to change deviceType in the middle of the game??

[charlie]

Hi
I have found that the Image was displayed diffently bettwen under the deviceType video::EDT_SOFTWARE2 and video::EDT_DIRECT3D9

//my Code:
BackGround=gGui->addImage(core::rect<int>(0,0,1024,768));
BackGround->setImage(Texture);

The Image was displayed more refined under video::EDT_SOFTWARE2.

But my 3D models can't run swimmingly under video::EDT_SOFTWARE2

So I want use video::EDT_DIRECT3D9,and change to video::EDT_SOFTWARE2 when I want to show Image.

Am I right ???

No, you want to use image dimensions of size 2^Nx2^M from which you crop the unnecessary (additional) parts. Otherwise the images are resized to the next larger power-of-two size with a rather simple algorithm.

Sorry
I can't comprehend your opinion.


My .bmp file is 1024*768
The Game Engin don't need to change anything.

And how can I solve the problem?

Your image width and height must be of power 2.
Something from this: 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, etc.
You have 768, which is 2x2x...x3. It's not power of 2. You must add some space to the bottom to make your image of size 1024x1024 (or remove some space from the bottom to make you image of size 1024x512).

Or if you really want to use an image with dimesnions 0f 1024x768 then use 1024x1024 and add some transparency to it so it'll look 1024x768
