Compressing Data
The following example compresses image data for use in an AVI file. It assumes
the compressor does not support the VIDCF_CRUNCH or VIDCF_TEMPORAL flags, but
it does support VIDCF_QUALITY. The example uses the ICCompressBegin macro, the ICCompress function, and the ICCompressEnd macro.
DWORD dwCkID;
DWORD dwCompFlags;
DWORD dwQuality;
LONG lNumFrames, lFrameNum;
// Assume dwNumFrames is initialized to the total number of frames.
// Assume dwQuality holds the proper quality value (0-10000).
// Assume lpbiOut, lpOut, lpbiIn, and lpIn are initialized properly.
// If OK to start, compress each frame.
if (ICCompressBegin(hIC, lpbiIn, lpbiOut) == ICERR_OK)
{
for ( lFrameNum = 0; lFrameNum < lNumFrames; lFrameNum++)
{
if (ICCompress(hIC, 0, lpbiOut, lpOut, lpbiIn, lpIn,
&dwCkID, &dwCompFlags, lFrameNum,
0, dwQuality, NULL, NULL) == ICERR_OK)
{
// Write compressed data to the AVI file.
// Set lpIn to the next frame in the sequence.
}
else
{
// Handle compressor error.
}
}
ICCompressEnd(hIC); // terminate compression
}
else
{
// Handle the error identifying the unsupported format.
}

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
