Hello, I’m AiRon, an automated tech support bot
While you wait for one of our customer support representatives, I can help you with your question.

When working with annotations like circles and polylines in the Apryse .NET SDK, adding labels involves setting the caption correctly. It seems you’re encountering issues with the SetContent() and SetShowCaption() methods not displaying as expected.

Some things you can try:

• Ensure that you are setting the content for the annotation using SetContent() method properly. This method is responsible for defining the text that should appear as a caption.


• Make sure you are calling SetShowCaption(true) on the annotation object to ensure that the caption is visible.


• Verify that the annotation is being added to the correct page and that it is being refreshed or updated after setting the caption.


• Check if the font and color properties are set correctly for the caption to be visible against the background.


• After setting these properties, ensure that you save or refresh the document to apply the changes.

Here are some resources that might help you:

• Edit annotation style properties: Learn how to set style properties like color and border, which might affect visibility.


• Add or edit PDF annotations: A guide on adding and editing various annotation types.


• Add link annotation to a document: Although this is for links, the principles of setting properties apply similarly to other annotations.


• Annotation style guide: Detailed information on how to customize the appearance of annotations.

Hopefully, this helps you solve your problem while you wait for a human to get back to you.

Hello,

Polyline and Circle annotations do not have text or labels by default. Instead, you can add this information to the annotation by modifying the appearance. There are some previous to help you get started with the code that you need to write to add the custom appearance. Please see them below:

How do add Decorations to an annotation in PDFViewWPF?

Question: I want to allow users to create line annotations that also have text on them. Answer: You will get the best overall result, by replicating/modifying the Line annotation tool code, and replace the RefreshAppearance code with your own custom appearance, which would include this extra text. Note that by default, double clicking an annotation such as a Line annotation will trigger (in most PDF readers) a popup dialog where users can enter “Hidden” text. You could re-use this behaviour …

Hi, to add a custom appearance to an annotation, see this forum post. https://groups.google.com/d/msg/pdfnet-sdk/VKV_M2r8c_8/ELadsgU3R9gJ The above just adds an image, but you can add any content you like. See the ElementBuilder sample on how to add text and paths. https://www.pdftron.com/pdfnet/samplecode/ElementBuilderTest.m.html Note though, that if someone opens up the PDF in a different PDF reader, and resizes the annotation, or in the case of freetext, changes the text, then your custo…
