Preparando-se para desenhar dados

  • Artigo

O exemplo a seguir mostra a sequência de inicialização que instrui o descompactador a desenhar tela inteira. Ele usa as macros ICDrawBegin e ICDrawEnd .

// 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. 
}
