Dear Sirs, 

I'm seaching for a pdf solution and found your product. Now I'm evaluating. 

In the documentation there is an example for creating a gradient:

 http://docs.telerik.com/devtools/aspnet-ajax/controls/pdfprocessing/concepts/colors-and-color-spaces

1.FixedContentEditor containerEditor = new FixedContentEditor(container);
2.LinearGradient linearGradient = new LinearGradient(new Point(0, 0), new Point(30, 30));
3.linearGradient.GradientStops.Add(new GradientStop(new RgbColor(0, 207, 0), 0));
4.linearGradient.GradientStops.Add(new GradientStop(new RgbColor(0, 102, 204), 0));
5. 
6.containerEditor.GraphicProperties.FillColor = linearGradient;
7.containerEditor.DrawRectangle(new Rect(10, 10, 48, 29));

If I copy these code I just get a monochrome rectangle filled with the color (0,102,204). 

 Any help would be fine.

 

many thanks in advance

Hello Gustav,

Thank you for writing.

I have modified the code for generating a linear gradient:
FixedContentEditor containerEditor = new FixedContentEditor(document.Pages.First());
LinearGradient linearGradient = new LinearGradient(new Point(0, 0), new Point(30, 30));
linearGradient.GradientStops.Add(new GradientStop(new RgbColor(0, 207, 0), 0));
linearGradient.GradientStops.Add(new GradientStop(new RgbColor(0, 102, 204), 1));
 
containerEditor.GraphicProperties.FillColor = linearGradient;
containerEditor.DrawRectangle(new Rect(10, 10, 48, 29));

We will update the code snippet in the help article as soon as possible.

As a token of our appreciation for reporting this I am updating your Telerik Points.

This code change doesn't appear to make a difference. The fill color in the pdf is still a solid color of the second color. Is this a bug? Is there a work around?

Hi Peter,

I just tried the snippet from the previous reply and it worked fine. Could you share the code you have used in order to create the LinearGradient?

Thanks. I've discovered my mistake. I had used Position.Translate to position the rectangle but it looks like the gradient points are not affected by Position.Translate
