I read your thread on foxite and I guess you also need a method for opening pdfs stored in string var. Am I right? This method can be added to Pdfiumviewer, e.g. OpenMemPDF(lcPdfData, ....)

[mksharmamk]

Yes
I am using StrToFile() and Shellexec to open the pdf files.
more helpful if this feature available in pdfium-vfp

Is possible to save with password without opening the old file

Thisform.PdfiumViewer.SaveDocument("c:\myfolder\OldPdfFile.pdf","c:\myfolder\NewPdfFileWithPassword.pdf", m.loPDFMeta)

Warm regards,
mk.

[dmitriychunikhin]

it's possible. Lets add method PipelineEncryptPDF(tcFileNameOld, tcFileNameNew, toPDFMetaOrPassword)
Usage sample

Thisform.PdfiumViewer.PipelineEncryptPDF("c:\myfolder\OldPdfFile.pdf", "c:\myfolder\NewPdfFileWithPassword.pdf", "MyPassword")
