PdfProcessing: Implement API for flattening form fields
This API should provide a method for removing all fields and widgets in the document and draw the default widget appearance in place of the removed widgets.

WORKAROUND: Sample implementation for flattening form fields may be seen in the FlattenFormFields method from the attached demo project.

Hi Claudio,

This is necessary if you are using a specific font that cannot be found on the operating system, or you are using the .NET standard assemblies. In both cases, the font will be embedded. We do not have an API that allows you to omit the font embedding at this point. We have a feature request for this as well: PdfProcessing: Implement a setting that allows choosing if the fonts should be embedded in the document

Unfortunately, I cannot suggest an alternative solution until the above feature is implemented. 

Thank you for your understanding.

Hi Dimitar,

 

The workaround in the first post work only if you embed fonts using FontsRepository.RegisterFont.

I need to NOT embed fonts so i not call RegisterFonts, but when i try to flatten pdf generated in this mode with the workararound code, raise a null reference exception reading the Content property of widget:

((Telerik.Windows.Documents.Fixed.Model.Annotations.VariableContentWidget)widget).Content

there is a patch for this?

Thanks

Hi Claudio,

Thank you for your feedback. I will forward it to the team.

Is there anything that prevents you from using the workaround in the first post? 

I am looking forward to your reply.

it is a surprise that after so many years, this basic feature is still not available where your competitor already has more advance features.

Hi Hector,

The task is not scheduled for implementation during the current release as we are working on more demanded functionalities for the library. Although the flattening is with a high priority in our backlog, at this point I cannot say when it might be available. Please, continue following this item so we can notify you when its status changes.

I know this is old, but in the code snippet there was one critical issue. When a textbox has NO data, the FormSource from Content.NormalContentSource will be NULL. Which will cause an issue when you get to FixedContentEditor.DrawForm(). Simple null check will avoid this issue since an empty textbox (with no borders/style) is just blank anyhow.

 

        private static void FlattenWidgetAppearance(FixedContentEditor pageEditor, Widget widget)
        {
            FormSource widgetAppearance = GetWidgetNormalAppearance(widget);

            if (widgetAppearance == null) return;

            pageEditor.Position.Translate(widget.Rect.Left, widget.Rect.Top);
            pageEditor.DrawForm(widgetAppearance, widget.Rect.Width, widget.Rect.Height);
        }
