We have a licensed version of GroupDocs viewer and are noticing a few issues, using the files in the attached zip:
Using the attached file, blank.docs, the ViewHandler.GetPdfFile call is erroring out. Seems like the pdf renderer is unable to handle certain documents that happen to have blank/empty data.
Using the attached file, b21 (1).docx, the amount of time it is taking to render both as pdf and as html is an abnormally long time. Performance seems slow for certain files or certain large files. What do you see as the cause, especially for this file, and what are suggestions to improve performance?
Using the attached file, IFTStmt.xlsx, both the rendering as pdf and as html are unexplainably removing some excel columns during render. Those columns become missing during render.
