I’m using aspose licensed version (version 11.8.1) to convert doc to html. I have a requirement to convert all .png images in the document to jpg, hence I’m using ImageCallBack event for the same. However, if a document contains objects like textbox, it is giving me below exception while saving the textbox as image. Can you help me?
System.NullReferenceException: Object reference not set to an instance of an obj
ect.
