.NET Image Libraries

What are some good image libraries for C#? Mainly for things such as painting in la开发者_StackOverflowyers. Or maybe a resource that can describe similar tasks?

With System.Drawing:

Image GetLayeredImage(int width, int height, params Image[] layers)
 {  Point layerPosition = new Point(0,0);
    Bitmap bm = new Bitmap(width,height);
    using(Graphics g = Graphics.FromImage(bm))
     { foreach(Image layer in layers) g.DrawImage(layer, layerPosition);
     }
    return bm;
 }

In the above example, a method, GetLayeredImage() is defined that accepts the width/height of the composite image, along with an array of Image objects, one for each layer. A point at (0,0) is defined as the top-left position for each layer. A Bitmap object is created and from that a Graphics object is created for drawing onto the bitmap. Each image in the array is then drawn onto the bitmap at the point (0,0)—you may want to change this by creating a different Point value for each layer. The resulting bitmap is then returned. The return value is an image with all the layers drawn.

Here's an example on how to call this method:

Image layer1 = Image.FromFile("layer1.jpg");
Image layer2 = Image.FromFile("layer2.jpg");
Image layeredImg = GetLayeredImage(width,height,layer1,layer2);
pictureBox.Image = layeredImg;

GDI+ comes installed with .NET

I've used the third-party tool called LeadTools Imaging Pro SDK with great success.

Usually anything like Paint.Net functionality will be obtained by way of third-party software or a lot of coding on your part.

Leadtools and Atalasoft DotImage are both pretty good. I've had good luck with Leadtools. You can use the builtin system.drawing features with Leadtools and probably DotImage.
