public Bitmap RenderWorkspace();

Multilayerviewer control has two methods:

public Bitmap RenderWorkspace();
public Bitmap RenderWorkspace(float renderingResolution);

Here are some questions:

1. Is there any default resolution when public Bitmap RenderWorkspace() is called.
2. Does the coordinate system on the bitmap image generated by calling
RenderWorkspace()match the coordinate system presented on multilayerviewer?

e.g in the attached sample bitmap genereated by calling RenderWorkspace(), there are two images: image 1 and image 2. If we crop them out using following parameter:

RectangleF rf = this.GetVObjectBounds();
float x = this.Transform.OffsetX;
float y = this.Transform.OffsetY;
float w = rf.Width;
float h = rf.Height;

Then generate the image by calling RenderWorkspace();

Then can we put the image back as exactly the same on the multilayerviewer by using other Aurigma graphic proceesing tools and above x, y, w, h parameters?
