Detailed Description

Texture2D class.

This class allows to easily create OpenGL 2D textures from images, text or raw data. The created Texture2D object will always have power-of-two dimensions. Depending on how you create the Texture2D object, the actual image area of the texture might be smaller than the texture dimensions i.e. "contentSize" != (pixelsWide, pixelsHigh) and (maxS, maxT) != (1.0, 1.0). Be aware that the content of the generated textures will be upside-down!

static void
setDefaultAlphaPixelFormat ( Texture2D::PixelFormat format )

static

sets the default pixel format for UIImagescontains alpha channel.

If the UIImage contains alpha channel, then the options are:

generate 32-bit textures: Texture2D::PixelFormat::RGBA8888 (default one)
generate 24-bit textures: Texture2D::PixelFormat::RGB888
generate 16-bit textures: Texture2D::PixelFormat::RGBA4444
generate 16-bit textures: Texture2D::PixelFormat::RGB5A1
generate 16-bit textures: Texture2D::PixelFormat::RGB565
generate 8-bit textures: Texture2D::PixelFormat::A8 (only use it if you use just 1 color)

How does it work ?

If the image is an RGBA (with Alpha) then the default pixel format will be used (it can be a 8-bit, 16-bit or 32-bit texture)
If the image is an RGB (without Alpha) then: If the default pixel format is RGBA8888 then a RGBA8888 (32-bit) will be used. Otherwise a RGB565 (16-bit texture) will be used.

This parameter is not valid for PVR / PVR.CCZ images.
