Member Function Documentation

virtual std::unique_ptr<CYIBitmap> CYIImageDecoderPNG::DecodeImpl ( const CYIString &  path, YI_DECODER_BITMAP_PARAMS *  pParams  )

overrideprotectedvirtual

Decode an asset at the specified path.

Implements CYIImageDecoder.

virtual std::unique_ptr<CYIBitmap> CYIImageDecoderPNG::DecodeImpl ( const uint8_t *  pData, uint32_t  nDataSize, YI_DECODER_BITMAP_PARAMS *  pParams  )

overrideprotectedvirtual

Decode an asset using pre-loaded file data pData and the nDataSize.

Implements CYIImageDecoder.

virtual bool CYIImageDecoderPNG::GetImageDimensions ( const CYIString &  path, uint32_t *  pnWidth, uint32_t *  pnHeight  )

overridevirtual

Returns true if the image information can be loaded via the asset package path; the width and height of the asset will be returned through the pnWidth and pnHeight parameters.

Reimplemented from CYIImageDecoder.
