Hi Blanca,

We have achieved your requirement to set the desired resolution for the image imported into diagram using a custom BitmapTool as shown in the code below.

public class CustomBitmapTool: BitmapTool

{

    public CustomBitmapTool(DiagramController controller) : base(controller)

    {

        this.Name = "CustomBitmapTool";

    }

 

    public override Node CreateNode(Image imgToInsert, RectangleF rectNodeBounds)

    {

        if (imgToInsert is Bitmap bitmap)

        {

            bitmap.SetResolution(72, 72);

        }

 

        return base.CreateNode(imgToInsert, rectNodeBounds);

    }

}

// To register the CustomBitmapTool
CustomBitmapTool customBitmapTool = new CustomBitmapTool(this.diagram1.Controller);

this.diagram1.Controller.RegisterTool(customBitmapTool);

// To activate the CustomBitmapTool
this.diagram1.Controller.ActivateTool("CustomBitmapTool");

We have also attached the sample for your reference. Please let us know if you need any further assistance.

Regards,

Prakash

Thank you, it works fine.

I have a last question, how can I export a bitmap image from .edd screen? Export to my computer.

Sometimes I need to export a image that I don't have or lose, how can I do this?
