Die einzigen von Paint unterstützten Dateitypen sind Bilddateien und Windows-bitmap-Formate. Add, replace, move, or resize images on the page using selections from the Objects list. You can also change the location for the output file by clicking on the "Browse" button after selecting "A folder on my computer". Open each image file at one time as the Paint cannot handle more than one images at the same time. Edit PDF according to your needs using preview and PDF editing tools provided on the toolbar, press “Apply” button to save the changes and get an edited PDF. Add a PDF file from your device (the “Add file(s)” button opens file explorer drag and drop is supported) or from Google Drive or Dropbox, select the language of input PDF document, and allow PDF Candy some time to process the PDF. If they do get changed appropriately, you can always parse for them in your application.PDFelement promises to provide a better way to open the PDF file in MS Paint. Most of the document won't be human readable but these timestamps should be. The other way you can visualize it is to simply open the PDF in Notepad and search for the properties. There may also be APIs that can be used to programmatically retrieve this metadata. The Creation field and Modified field should have different timestamps.
One is when you open the document in Acrobat and hit Ctrl-D to view Document Properties. If the editor your users use does change ModDate or xmp:ModifyDate, then you should be able to see it in two places. However not all tools adhere to this quite a few simply leave all metadata untouched, so this method of checking isn't 100% reliable unless you know what PDF editor your users employ. Strictly speaking, modifying the PDF should change its ModDate or xmp:ModifyDate without changing its CreationDate. Are the users modifying the PDF using Acrobat? If so then what Danio mentioned above should work.
