Ability to superimpose and adjust text on DWF images, thus allowing some degree of editing the resulting render output

How to ability to superimpose and adjust text on DWF images

Issue: How to ability to superimpose and adjust text on DWF images.

Tips: To do this, you need to create a DwfWhipText, set the necessary parameters to it and add it to the drawing using the AddElement method, or to remove it, you can use the RemoveElement method

Example:

using var dwimg = (DwfImage)Image.Load(file);

CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
rasterizationOptions.DrawType = CadDrawTypeMode.UseObjectColor;

PdfOptions pdfOptions = new PdfOptions();
pdfOptions.VectorRasterizationOptions = rasterizationOptions;

DwfWhipText text = new DwfWhipText();
text.Color = Color.Red;
text.Text = new CAD.FileFormats.Dwf.Whip.Objects.DwfString("THIS IS A TEST TEXT");
text.Position = new CAD.FileFormats.Dwf.Whip.Objects.DwfWhipLogicalPoint(40000, 70000);
text.Font = new CAD.FileFormats.Dwf.Whip.Objects.Service.DwfWhipFont();
text.Font.Name = new CAD.FileFormats.Dwf.Whip.Objects.Service.Font.DwfWhipOptionFontName();
text.Font.Name.Value = new CAD.FileFormats.Dwf.Whip.Objects.DwfString("times new roman");
text.Font.Height = new CAD.FileFormats.Dwf.Whip.Objects.Service.Font.DwfWhipOptionFontHeight();
text.Font.Height.Value = 2000;
text.IsVisible = true;

dwimg.AddElement(0, text);
image.Save(outFileAdded, pdfOptions);

dwimg.RemoveElement(0, count);
image.Save(outFileAdded, pdfOptions);
