Question

I have an image

image = Image.FromStream(file.InputStream);

How I can use the property System.Drawing.Size for resize them or where this property used for?

Can I direct resize the image without change them to bitmap or without loss any quality. I not want corp just resize them.

How I can do this in C#?

Answer 1

You can use Bitmap class’s constructor to help, and actually Bitmap is a subclass of Image.

var image_16 = new System.Drawing.Bitmap(image, new Size(16, 16));
