Detailed Description

Codec specialized in loading ASTC (ARM Adaptive Scalable Texture Compression) images.

Remarks: We implement our own codec here since we need to be able to keep ASTC data compressed if the card supports it.

Member Function Documentation

◆ decode() [1/2]

DecodeResult Ogre::ASTCCodec::decode ( const DataStreamPtr & input ) const

overridevirtual

Deprecated:

Reimplemented from Ogre::Codec.

◆ magicNumberToFileExt()

String Ogre::ASTCCodec::magicNumberToFileExt	(	const char *	magicNumberPtr,
		size_t	maxbytes
	)		const

overridevirtual

Maps a magic number header to a file extension, if this codec recognises it.

Parameters

magicNumberPtr	Pointer to a stream of bytes which should identify the file. Note that this may be more than needed - each codec may be looking for a different size magic number.
maxbytes	The number of bytes passed

Returns: A blank string if the magic number was unknown, or a file extension.

Implements Ogre::Codec.

◆ getType()

String Ogre::ASTCCodec::getType ( ) const

overridevirtual

Returns the type of the codec as a String.

Implements Ogre::Codec.

◆ startup()

static void Ogre::ASTCCodec::startup ( void )

static

Static method to startup and register the ASTC codec.

◆ shutdown()

static void Ogre::ASTCCodec::shutdown ( void )

static

Static method to shutdown and unregister the ASTC codec.
