Annotation - MergeXFDF does not include the rotation of free text in .NET Framework

Hi William,

After calling MergeXFDF, you need to call doc.refreshAnnotAppearances. For more information on why you need this, see the following forum post:

After merging XFDF data the annotations that appear depend on what software is being used?

Question: I use the following code to merge XFDF data (annotations) into a PDF. FDFDoc fdf_doc = FDFDoc.createFromXFDF("XFDF File Path"); fdf_doc.save("FDF File Path"); PDFDoc pdoc = new PDFDoc("PDF File Path"); pdoc.initSecurityHandler(); pdoc.fdfMerge(fdf_doc); pdoc.save("PDF File Output Path", SDFDoc.e_linearized, null); pdoc.close(); But I see the following in different PDF viewers. Chrome browser, few markups are not visible like Cloud, Polygon, Polyline, Arrow and Line. Mozilla browse…

This PDF specification also be default only allows rotations of 90 degrees. If you are doing partial rotations you will need to add the following lines of code after the MergeXFDF

RefreshOptions refreshOptions = new RefreshOptions();
refreshOptions.SetUseNonStandardRotation(true);
doc.refreshAnnotAppearances(refreshOptions);
