unsigned short MaliSDK::ETCHeader::getHeight ( void )

The height of the original texture.

The height of a compressed texture is padded to 4x4 blocks by the compression method. The resulting height of the compressed texture may therefore be larger if it's original height was not a multiple of 4. By using the unpadded height, the original texture can be drawn.

Returns: The height of the original texture without padding.

unsigned short MaliSDK::ETCHeader::getHeight ( void )

The height of the original texture.

The height of a compressed texture is padded to 4x4 blocks by the compression method. The resulting height of the compressed texture may therefore be larger if it's original height was not a multiple of 4. By using the unpadded height, the original texture can be drawn.

Returns: The height of the original texture without padding.

Definition at line 53 of file ETCHeader.cpp.

unsigned short MaliSDK::ETCHeader::getPaddedHeight ( void )

The height of the compressed texture with the padding added.

The height of a compressed texture is padded to 4x4 blocks by the compression method. The resulting height of the compressed texture may therefore be larger if it's original height was not a multiple of 4.

Returns: The height of the compressed texture with padding included.

unsigned short MaliSDK::ETCHeader::getPaddedHeight ( void )

The height of the compressed texture with the padding added.

The height of a compressed texture is padded to 4x4 blocks by the compression method. The resulting height of the compressed texture may therefore be larger if it's original height was not a multiple of 4.

Returns: The height of the compressed texture with padding included.

Definition at line 63 of file ETCHeader.cpp.

unsigned short MaliSDK::ETCHeader::getPaddedWidth ( void )

The width of the compressed texture with the padding added.

The width of a compressed texture is padded to 4x4 blocks by the compression method. The resulting width of the compressed texture may therefore be larger if it's original width was not a multiple of 4.

Returns: The width of the compressed texture with padding included.

unsigned short MaliSDK::ETCHeader::getPaddedWidth ( void )

The width of the compressed texture with the padding added.

The width of a compressed texture is padded to 4x4 blocks by the compression method. The resulting width of the compressed texture may therefore be larger if it's original width was not a multiple of 4.

Returns: The width of the compressed texture with padding included.

Definition at line 58 of file ETCHeader.cpp.

GLsizei MaliSDK::ETCHeader::getSize ( GLenum internalFormat )

The size of the compressed texture with the padding added.

The size is computed as padded width multiplied by padded height.

Parameters

[in] internalFormat The internal format of the compressed texture.

Returns: The size of the compressed texture with padding included.

GLsizei MaliSDK::ETCHeader::getSize ( GLenum internalFormat )

The size of the compressed texture with the padding added.

The size is computed as padded width multiplied by padded height.

Parameters

[in] internalFormat The internal format of the compressed texture.

Returns: The size of the compressed texture with padding included.

Definition at line 66 of file ETCHeader.cpp.

unsigned short MaliSDK::ETCHeader::getWidth ( void )

The width of the original texture.

The width of a compressed texture is padded to 4x4 blocks by the compression method. The resulting width of the compressed texture may therefore be larger if it's original width was not a multiple of 4. By using the unpadded width, the original texture can be drawn.

Returns: The width of the original texture without padding.

unsigned short MaliSDK::ETCHeader::getWidth ( void )

The width of the original texture.

The width of a compressed texture is padded to 4x4 blocks by the compression method. The resulting width of the compressed texture may therefore be larger if it's original width was not a multiple of 4. By using the unpadded width, the original texture can be drawn.

Returns: The width of the original texture without padding.
