Preparing to Draw Data
The following example shows the initialization sequence that instructs the
decompressor to draw full-screen. It uses the
ICDrawBegin and
ICDrawEnd macros.
// Assume lpbiIn has the input format, dwRate has the data rate.
if (ICDrawBegin(hIC, ICDRAW_QUERY | ICDRAW_FULLSCREEN, NULL, NULL,
NULL, 0, 0, 0, 0, lpbiIn, 0, 0, 0, 0, dwRate,
dwScale) == ICERR_OK)
{
// Decompressor supports this drawing so set up to draw.
ICDrawBegin(hIC, ICDRAW_FULLSCREEN, hPal, NULL, NULL, 0, 0, 0,
0, lpbiIn, 0, 0, lbpi->biWidth, lpbi->biHeight, dwRate,
dwScale);
.
. // Start decompressing and drawing frames.
.
// Drawing done. Terminate procedure.
ICDrawEnd(hIC);
}
else
{
// Use another renderer to draw data on the screen;
// ICDraw does not support the format.
