GLTextureFormat struct
Translates backend-neutral pixel formats into OpenGL formats.
Translation table of the OpenGL backend: maps each logical PixelFormat (plus a BGR/BGRA channel-order flag) to the OpenGL internal format, external format and pixel data type consumed by the texture upload calls, and verifies device support for the compressed families. This is the only place the OpenGL texture-format constants live; pipeline code only ever names a PixelFormat.
Public static functions
- static void Resolve(PixelFormat format, bool bgr, GLint& internalFormat, GLenum& externalFormat, GLenum& dataType)
- Resolves a pixel format into its OpenGL internal format, external format and data type.
- static void CheckSupport(PixelFormat format)
- Verifies that the device supports the given pixel format, aborting if it does not.
Function documentation
static void nCine::
Resolves a pixel format into its OpenGL internal format, external format and data type.
| Parameters | |
|---|---|
| format | Backend-neutral pixel format |
| bgr | Whether the external channel order is BGR/BGRA instead of RGB/RGBA |
| internalFormat | Receives the sized OpenGL internal format |
| externalFormat | Receives the external OpenGL format |
| dataType | Receives the OpenGL pixel data type |
