Problems with SaveWithAnnotations in memorystream

Post by zoao » Wed Jul 15, 2009 9:39 pm

When try save image with annotation using memorystream, this throw exception in Seek() because the stream is close, but the same code for save image without annotation, work correct.

Code: Select all

byte[] b;
using (MemoryStream ms = new MemoryStream())
{
	mwImageControl1.Viewer.Images[0].SaveWithAnnotations(ms, new Vintasoft.Imaging.Encoders.JpegEncoder(80));
	ms.Seek(0, SeekOrigin.Begin);
	b = ms.ToArray();
}

Thanks, João

Hello Alex,

I thought that the method SaveWithAnnotations, save the image with the annotations merged, but now noticed that it saves the annotations embedded in the jpg, maintaining the original image.

What I want is a method GetImageWithAnnotations of AnnotationController, which merge the image with the annotations.

Thanks, João
