inlineoverridevirtual

IImage related functions

Implements IImage.

Decode()

bool CImageDecoder::Decode ( unsigned char *const pixels, unsigned int width, unsigned int height, unsigned int pitch, unsigned int format )

overridevirtual

Decodes the previously loaded image data to the output buffer in 32 bit raw bits.

Parameters

pixels	The output buffer
width	The width of the image
height	The height of the image
pitch	The pitch of the output buffer
format	The format of the output buffer (JpegIO only)

Returns

true if the image data could be decoded to the output buffer

Implements IImage.

IsCreated()

LoadImageFromMemory()

bool CImageDecoder::LoadImageFromMemory ( unsigned char * buffer, unsigned int bufSize, unsigned int width, unsigned int height )

overridevirtual

Load an image from memory with the format m_strMimeType to determine it's size and orientation.

Parameters

buffer	The memory location where the image data can be found
bufSize	The size of the buffer
width	The ideal width of the texture
height	The ideal height of the texture

Returns

true if the image could be loaded

Implements IImage.

LoadInfoTag()
