◆ PixelFormat

enum Ogre::PixelFormat

The pixel format used for images, textures, and render surfaces.

Note
the components are specified in "packed" native byte order. For PF_BYTE_* formats this means that platform endianess changes the order: e.g. Ogre::PF_BYTE_RGBA on little endian (x86) forms an integer as Ogre::PF_A8B8G8R8, while on big endian it "packs" as Ogre::PF_R8G8B8A8

◆ PixelFormatFlags

enum Ogre::PixelFormatFlags

Flags defining some on/off properties of pixel formats.

Enumerator
PFF_HASALPHA 

This format has an alpha channel.

PFF_NATIVEENDIAN 

Format is in native endian.

Generally true for the 16, 24 and 32 bits formats which can be represented as machine integers.

PFF_LUMINANCE 

This is an intensity format instead of a RGB one.

The luminance replaces R,G and B. (but not A)

PFF_INTEGER 

This is an integer format.

◆ PixelComponentType

enum Ogre::PixelComponentType

Pixel component format.

Enumerator
PCT_BYTE 
PCT_SHORT 

Byte per component (8 bit fixed 0.0..1.0)

Short per component (16 bit fixed 0.0..1.0))

PCT_FLOAT32 

16 bit float per component

PCT_SINT 

32 bit float per component

PCT_UINT 

Signed integer per component.

PCT_COUNT
