// Usage of IconExtractor class:
// Construct an IconExtractor object with a file.
IconExtractor ie = new IconExtractor(@"D:\sample.exe");
// Get the full name of the associated file.
string fileName = ie.FileName;
// Get the count of icons in the associated file.
int iconCount = ie.Count;

// Extract all the icons in one go.

// Usage of IconUtil class:
// Split the variations of icon0 into separate icon objects.
Icon[] splitIcons = IconUtil.SplitIcon(icon0);
// Convert an icon into bitmap. Unlike Icon.ToBitmap() it preserves the transparency.
Bitmap bitmap = IconUtil.ToBitmap(splitIcon[1]);
// Get the bit count of an icon.
