Decompressing Data

The following example shows how an application can initialize a decompressor using the ICDecompressBegin8ELI.K macro, decompress a frame sequence using the ICDecompressVY6_HF function, and terminate decompression using the ICDecompressEnd5OSW3L macro.

LPBITMAPINFOHEADER lbpiIn, lpbiOut;

LPVOID             lpIn, lpOut;

LONG               lNumFrames, lFrameNum;

// Assume lpbiIn and lpbiOut are initialized to the input and output

// format and lpIn and lpOut are pointing to the buffers.

if (ICDecompressBegin(hIC, lpbiIn, lpbiOut) == ICERR_OK)

{ 

    for (lFrameNum = 0; lFrameNum < lNumFrames, lFrameNum++)

    { 

        if (ICDecompress(hIC, 0, lpbiIn, lpIn, lpbiOut,

            lpOut) == ICERR_OK)

        { 

            // Frame decompressed OK so we can process it as required.

        }

        else

        { 

            // Handle the decompression error that occurred.

        }

    }

    ICDecompressEnd(hIC);

}

else

{ 

    // Handle the error identifying an unsupported format.

}
