Add Selection Tolerance to Annotations with Whitespace

WebViewer Version: 8.6.0

Hello PDFTron Support Team,

I’m having a problem with the selection SignatureAnnotations. I’m using the SignatureCreationTool to create a signature with a base64 image. The signatures I use are png files with a transparent background. If I have signatures with a thin pen line, it’s hard to actually select the annotation. Is there a way to make the entire rectangular area clickable or add some tolerance to the clickable area?
