Hello,

Here is the code snippet which illustrates how to set gradient color for rectangle vector object:
Code:
Aurigma.GraphicsMill.WinControls.RectangleVObject rectangle = new Aurigma.GraphicsMill.WinControls.RectangleVObject(0F, 0F,multiLayerViewer1.WorkspaceWidth/10, multiLayerViewer1.WorkspaceHeight/10);
//Modify stroke and fill parameters
rectangle.Pen = new System.Drawing.Pen(System.Drawing.Color.BlanchedAlmond, 10F);
//Fill gradient 
rectangle.Brush = new System.Drawing.Drawing2D.LinearGradientBrush(new Point(0, 10),new Point(200, 10), System.Drawing.Color.Wheat, System.Drawing.Color.Black);
//Add the rectangle to a layer
multiLayerViewer1.Layers[0].VObjects.Add(rectangle);

Hi,

It is possible too:
Code:

...
using (Brush aGradientBrush = new System.Drawing.Drawing2D.LinearGradientBrush(new Point(0, 10), new Point(200, 10), Color.Blue, Color.Red))
  rectangle.Pen = new System.Drawing.Pen(aGradientBrush, 10F);
...

Hi,

Sorry, but it is impossible. Pen and brush use standard LinearGradientBrush class to set the gradient color. Unfortunately, there is no way to apply it to ImageVObject of Graphics Mill.

Hello,

Could you please post the error details? Also, please share more code snippet with me since it is not quite clear what the background is.

Okay, thank you for the details. I checked it, and confirm that it is impossible to set gradient color of SolidBackgroundVObject. I recommend you to use lock RectangleVObject as a background, and set the gradient color in the way described above of this thread.

rectangle.Pen = new System.Drawing.Pen(aGradientBrush, 10F);" to make gradient pen color. but its making error with "multiLayerViewer.SaveState()". pls provide me a solution...

Hello,

Okay, I tried the sample, and got the error. Unfortunately, here setting gradient color for Pen is impossible. There is Pen is a class of System.Drawing, which has its own Color property. It cannot be gradient color. Therefore, you face the exception.
