I found the Watermark assemble, and successfully added with GAC reference, but can't declare this class.
Assemble here:
http://easywatermark.ru/EasyWatermarkLib
EasyWatermarkLib with XML-comments (IntelliSense)
I have saved EasyWatermarkLib.dll in the C:\Program Files\ZennoLab\ZennoPoster Standard\Progs\ExternalAssemblies
and after that added in the GAC
But the code return error:
using EasyWatermark;
// loading watermark template
Pattern p = new Pattern(@"C:\template.xml");
// put watermark to image C:\image.jpg
// setup fixed dimensions of image 500x500px you can use 0 for auto size / for example 500, 0
Image watermarkImage = p.GetImage(@"C:\картинка.jpg", 500, 500);
// save image with watermark to file C:\test1.jpg
watermarkImage.Save(@"C:\пример1.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
