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



It seems like you’re encountering an issue with rendering annotations in WebViewer, particularly with the appearance of annotations not being properly drawn. This is often related to the way custom appearances are handled or issues with the rendering logic.

Some things you can try:

  • Ensure that the annotation’s custom appearance is correctly defined and that all necessary data is available for rendering.

  • Use generateInlineAppearances when exporting annotations to ensure that the appearance data is included in the XFDF string.

  • Check if there are any custom draw handlers that might be interfering with the default rendering process.

  • Verify that all dependencies and necessary files are correctly loaded and accessible in your environment.
