I am trying to create a new icon set from an existing one by smooth scaling each of it’s pixmaps. When I try to do this, I get an assertion when I am trying to convert the image back to a pixmap just before setting the new pixmap in the iconset. I looked into it further and found that even a simple round-trip to and from an image is not working, and I receive the following assertions:

Qt Code: 
  1. ASSERT: "hBitmap" in kernel\qpixmap_win.cpp (117)
  2.  ASSERT: "data->realAlphaBits" in kernel\qpixmap_win.cpp (118)

Here is some sample code that shows what I was trying to do:

Qt Code: 
  1. QIconSet  *dest = new guiIconSet;
  2.  
  3.     for ( int size = 0 ; size < 2 ; size++ )
  4.     {
  5.         for ( int mode = 0 ; mode < 3 ; mode++ )
  6.         {
  7.             for ( int state = 0 ; state < 2 ; state++ )
  8.             {
  9.                 // Get the image from the source iconsets pixmap
  10.                 srcImg = pixmap((QIconSet::Size )size, (QIconSet::Mode )mode, (QIconSet::State )state);
  11.  
  12.                 if ( ! srcImg.isNull() )
  13.                 {
  14.                     guiPixmap destPm;
  15.  
  16.                     // Get the dest pixmap from the dest image
  17.                     destPm = srcImg;
  18.  
  19.                     if ( ! destPm.isNull() )
  20.                         dest->setPixmap(destPm, (QIconSet::Size )size, (QIconSet::Mode )mode, (QIconSet::State )state);   
  21.                 }
  22.             }
  23.         }
  24.     }
