The code sample is a function that takes an image as input and returns an Icon object. The function also takes a boolean parameter that specifies whether to keep the aspect ratio or not.
Icon MakeIcon(Image img, int size, bool keepAspRatio) {
Bitmap square = new Bitmap(size, size);
Graphics g = Graphics.FromImage(square);
int x, y, w, h;
if(!keepAspRatio|| img.Height == img.Width) {
x = y = 0;
w = h = size;
} else {
float r = (float)img.Width / (float)img.Height;
if(r > 1) {
w = size;
h = (int)((float)size / r);
x = 0; y = (size - h) / 2;
} else {
w = (int)((float)size * r);
h = size;
y = 0; x = (size - w) / 2;
}
}
g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;
g.DrawImage(img, x, y, w, h);
g.Flush();
return Icon.FromHandle(square.GetHicon());
}
