Hello,

We have need your help for the following situation about zoom feature of MultiLayerViewer:

We have a MultiLayerViewer1 with some ImageVObjects on it

1. we do following
MultiLayerViewer1.ZoomMode = ZoomMode.None;
MultiLayerViewer1.Zoom = 0.95
System.Drawing.Bitmap _image= MultiLayerViewer1.RenderWorkspace();

2. we then do following
MultiLayerViewer1.ZoomMode = ZoomMode.None;
MultiLayerViewer1.Zoom = 0.25
System.Drawing.Bitmap _image2= MultiLayerViewer1.RenderWorkspace();


but both _image and _image2 are the same and no zooming happens. What should we do so that zooming can happen when to do RenderWorkspace?

Thank you.

Hi,

If you need get image with max width or height is 250px you should use following code.
Code:



var size = 250;

// MultiLayerViewer1 is an Canvas.
var dpi = size * 72 / Math.Max(MultiLayerViewer1.WorkspaceWidth, MultiLayerViewer1.WorkspaceHeight);

var img250 = MultiLayerViewer1.RenderWorkspace(dpi, ColorSpace.Rgb, RgbColor.White);

Hello,

we use Aurigma Graphics Mill 5.5 but do not see this overloaded RenderWorkspace method for
MultiLayerViewer.

Thank you.

Hi,

I am sorry. Could you try to use following method with parameter to get bitmap.

Code:
MultiLayerViewer.RenderWorkspace Method (Single)
Please find more information here: http://www.aurigma.com/d...Workspace_1_7a94462e.htm
