Shadow Class

Syntax

public sealed class Shadow : Transform

Remarks

When you apply this effect, the image drops a shadow with specified parameters (taking into account transparent areas of the image). This effect is ideal for creating artistic texts, logos, etc.

You can specify a number of shadow parameters. HorizontalOffset and VerticalOffset specify offset of the shadow relatively the image. Color means the shadow color. To make shadow looking more realistic, it is blurred. You can set blur Radius (amount of the shadow fuzziness). Property EnlargeToFit can be used to specify if the transform should increase size of the image to fit the shadow or it should truncate the shadow which is out of the original image (makes sense to set it to true when you create artistic thumbnails).

Examples

The following code gets the thumbnail from an image EXIF metadata, applies the Shadow transform on it, and saves the result:

using (var jpegReader = new JpegReader(@"Images\in.jpg"))
{
    using (var thumbnail = (Bitmap)(jpegReader.Exif[ExifDictionary.Thumbnail]))
    {
        //Add the alpha channel
        if (!thumbnail.HasAlpha)
            thumbnail.Channels.SetAlpha(1);

        //Apply Shadow transform
        thumbnail.Transforms.Shadow(RgbColor.Black, 4, 4, 10, true);

        //Flatten alpha channel
        thumbnail.Channels.RemoveAlpha(RgbColor.White);
        thumbnail.Save(@"Images\out.jpg");
    }
}
