Possible to read a PDF file directly from memory?

[flashbob]

Is it possible to read/open PDF-Content directly from memory instead from file ?

I would like to save the pdf file into a database an then load it directly into memory in order to open it with default pdf reader.
At the moment I save the PDF file to a temporary file before opening it with RunProgram(...).

Perhaps the same procedure could also be used to display images...

Thx in advance.

If you need an external tool to open your pdf, you need to write it to a file, unless I misunderstood your question.

If you use pdfium to render the document, then you can use:

Code: Select all

                                                                    ;// Function: FPDF_LoadMemDocument
                                                                    ;//          Open and load a PDF document from memory.
                                                                    ;// Parameters:
                                                                    ;//          data_buf    -   Pointer to a buffer containing the PDF document.
                                                                    ;//          size        -   Number of bytes in the PDF document.
                                                                    ;//          password    -   A string used as the password for the PDF file.
                                                                    ;//                          If no password is needed, empty or NULL can be used.
                                                                    ;// Return value:
                                                                    ;//          A handle to the loaded document, or NULL on failure.
                                                                    ;// Comments:
                                                                    ;//          The memory buffer must remain valid when the document is open.
                                                                    ;//          The loaded document can be closed by FPDF_CloseDocument.
                                                                    ;//          If this function fails, you can use FPDF_GetLastError() to retrieve
                                                                    ;//          the reason why it failed.
  Prototype FPDF_LoadMemDocument(*data_buf, size, password.p-unicode);

Thanks for the info, but I don't want to use additional libs at the moment...
