Resize Images Online in ASP.NET Apps

The ImageSharp.Web API allows software developers to change the size of their images with just a couple of lines of .NET code. To resize an image, first your need to download the image and load it into the memory. Once loaded the next step is to resize the image to create the output image. Once the resize process is completed you save the cropped image to the response stream and return it to the browser. Apart from the basic resizing operations, ImageSharp.Web also offers more advanced image processing features.

Reading & Writing Image Metadata

The Open Source library ImageSharp.Web has included capability for reading and writing metadata inside web applications.

The library has included several important features for working with metadata, such as accessing & loading metadata, reading metadata, writing metadata and so on.

        private static void WriteMetadata(Image image)
    {
        if (image.Metadata.IptcProfile == null)
            image.Metadata.IptcProfile = new IptcProfile();

        image.Metadata.IptcProfile.SetValue(IptcTag.Name, "Pokemon");
        image.Metadata.IptcProfile.SetValue(IptcTag.Byline, "Thimo Pedersen");
        image.Metadata.IptcProfile.SetValue(IptcTag.Caption, "Classic Pokeball Toy on a bunch of Pokemon Cards. Zapdos, Ninetales and a Trainercard visible.");
        image.Metadata.IptcProfile.SetValue(IptcTag.Source, @"https://rb.gy/hgkqhy");
        image.Metadata.IptcProfile.SetValue(IptcTag.Keywords, "Pokemon");
        image.Metadata.IptcProfile.SetValue(IptcTag.Keywords, "Pokeball");
        image.Metadata.IptcProfile.SetValue(IptcTag.Keywords, "Cards");
        image.Metadata.IptcProfile.SetValue(IptcTag.Keywords, "Zapdos");
