Member Function Documentation

Black()

void vdecmpeg4::M4Image::Black

(

)

Clear buffer.

Set buffer to black

create()

M4Image * vdecmpeg4::M4Image::create ( M4Decoder *  decoder, int16  width, int16  height, bool  poolMem = true  )

static

Construction and allocation of image helper.

Constructor for image buffer.

The provided image buffer is 'extended' with a padding area around all borders. Currently, this padding area is 32 pixel and this size is FIXED, because some assembler routines just ASSUME this size.

Parameters

decoder
width	original image width
height	original image height

Returns

destroy()

void vdecmpeg4::M4Image::destroy ( M4Image *&  pImage, M4Decoder *  decoder  )

static

Destruction.

Static destruction

Parameters

pImage

getDecoder()

M4Decoder & vdecmpeg4::M4Image::getDecoder ( ) const

inline

Return reference to our decoder.

operator delete()

void vdecmpeg4::M4Image::operator delete ( void *  ptr )

operator new()

void * vdecmpeg4::M4Image::operator new ( size_t  sz, M4MemHandler &  memSys  )

inline

poolMemCb()

void vdecmpeg4::M4Image::poolMemCb ( void *  memPtr, uint32  size, uint32  poolFlags, void *  userData  )

static

Pool mem allocation callback.

Static callback for pool memory allocation

Parameters

memPtr
poolFlags
userData

RefAdd()

void vdecmpeg4::M4Image::RefAdd ( )
