Image processing library in asp.net (using C#) without flash

Question

I have the following requirement wherein I have to implement a paint brush kind of feature in a asp.net web application. Basically it should support resizing, drawing lines, squares, etc and a whole lot of features like a paint brush. I was googling out image processing libraries in internet.
I found some - but the problem is most of them is with flash. I was looking for some option without flash since the application should run on a ipad also.

Can you people suggest some good image processing libraries which I can use in my asp.net (using C#) application.?

I have done good enough research regarding them. I do not have much time to download the trial versions and try each and every library. So I need the help of you all to suggest me something based on experience.

Answer 1

For the Image Resizing and cropping you can use Image Resizer and for drawing lines, squares, etc you should use HTML5 Canvus .

There are a lot of good libraries and tutorials for HTML5 Canvus.

Its easy to use and is available at Nuget .

var settings = new ResizeSettings {
  MaxWidth = thumbnailSize,
  MaxHeight = thumbnailSize,
  Format = "jpg"
};
settings.Add("quality", quality.ToString());
ImageBuilder.Current.Build(inStream, outStream, settings);
resized = outStream.ToArray();

You can install it using Nuget

PM> Install-Package ImageResizer
