Drawing a image in 3D space

I have an image in memory, I mean I know width, height, type (eg. ECF_A8R8G8B8) and a pointer to bytes data.
How can I create a ITexture on the fly? (without write a png file to the disk and then driver->getTexture( "my_file" ) - I cand do that but it's not quite a cool option).
Thank you!

IImage* IVideoDriver::createImageFromData(ECOLOR_FORMAT format, const core::dimension2d<s32> &size, void *data, bool ownForeignMemory=false, bool deleteMemory=true)
ITexture* IVideoDriver::addTexture (const c8 *name, IImage *image)

IImage* IVideoDevice::createImageFromData(ECOLOR_FORMAT format, const core::dimension2d<s32>& size, void *data,...);
ITexture * IVideoDevice::addTexture(const c8* name, IImage* image);
[UPDATE - damn yoooooooouuuuuuu!

Thank you very much!
I new about
Code: Select all
IImage* IVideoDevice::createImageFromData(ECOLOR_FORMAT format, const core::dimension2d<s32>& size, void *data,...);
And I thaught that
Code: Select all
ITexture * IVideoDevice::addTexture(const c8* name, IImage* image);
will load a texture from a file ... I should look at the code

Now I have another "problem". How can I draw that texture in 3D space (not 2D, using IVideoDriver->draw2DImage( ... );
I want to draw it in an 3d quadrilateral.
//later
And of course scale, rotate.
