    TITLE  :  Creating a Presentation Space Bitmap under OS/2.




                      Bitmap Creation under OS/2 2.0.
                      ===============================

       Created presentation spaces DO NOT have a default bitmaps
  associated with them. The following code shows how to created
  bitmap from scratch and associate it with a presentation space.

  // ==============================================================
  // |  Creates a bitmap and associated the bitmap of size area   |
  // | into the HPS passed in the parameter hps. A handle to the  |
  // | newly created bitmap is returned.                          |
  // ==============================================================

  HBITMAP CreateSetBitmap(HPS hps, RECTL area)
  {

       BITMAPINFOHEADER2 BitmapInfo;     // Header of bitmap
       HBITMAP theBitmap;                // Bitmap created

       // Clear the bitmap information header structure
       memset(&BitmapInfo, 0, sizeof(BITMAPINFOHEADER2) );

       // Set Bitmap information header fields
       BitmapInfo.cbFix = sizeof(BITMAPINFOHEADER2) ;

       // Set the area of the bitmap in the presentation space
        BitmapInfo.cx = area.xRight + 1;
       BitmapInfo.cy = area.yTop + 1;

       // Number of planes for the graphcis mode
       BitmapInfo.cPlanes = 1L;

       // Bit count for color
       BitmapInfo.cBitCount = 4L;

       // No compression
       BitmapInfo.ulCompression = BCA_UNCOMP;

       // 16 Bit color
       BitmapInfo.cclrUsed = 16;

       // Create the bitmap
       theBitmap = GpiCreateBitmap(hps, &BitmapInfo,
