Hello lakshan,

The FreeTextAnnotation has properties for auto-sizing:

AutoSizeTypes:
NONE	string	Freetext stays at fixed size
AUTO	string	Autosize to content
FIXED_WIDTH	string	Width cannot be changed
FIXED_HEIGHT	string	Height cannot be changed

Does this work for you?

Set that property but it’s not working

Not resized, some texts are missing

Hello lakshan,

This is how you use the API:

freeTextAnnotation.setAutoSizeType(instance.Core.Annotations.FreeTextAnnotation.AutoSizeTypes.AUTO)
