Decompressing Data
The following example shows how an application can initialize a decompressor
using the
ICDecompressBegin macro, decompress a frame sequence using the
ICDecompress function, and terminate decompression using the
ICDecompressEnd 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.
