    Hello
    When i export digrams to pdf from V14 and earlier looks blurry.


    I have attached an example project:
    Spread_Win_Blurry_Digrams.zip

    Best regards

    Hi Mikael,

    Thanks for sharing the sample.

    We are discussing the behavior with the devs. We will revert back to you when we have any update. (Internal Tracking ID : SPNET-13562)

    Hello
    A workaround for this is to use the "Microsoft Print to PDF" instead. This makes the Diagrams better.
    In code this means:
    Sheet.PrintInfo.Printer = "Microsoft Print to PDF"


    The bad thing about this is when you use the
    spread.PrintSheet(-1);

    You get one file per sheet. Dont know i this can be fixed somehow.
    You have to have the Microsoft Print To PDF installed to. But its free.

    Hi Mikael,

    As per the devs, Reduction in exported image quality is a limitation of the current PDF export logic because all images are exported as JPEG which causes quality reduction.

    I have also tried setting Printer to "Microsoft Print to PDF" with the latest build (Spread 14) but still I am getting the same print quality as before. Could you please share the spread version you are using?

    And also if possible please share a sample for the same.

    Hello
    Sorry i tried an export from Spread.net 8.2 and there is where i found the better quality with the "Microsoft Print to PDF".

    The first post shows the problem with the new version. Can you change from JPEG to a none destroying format ?

    Hi Mikael,

    We are sorry, but currently there is no such plan for changing the export format. However, we will inform you when there is any update regarding the same in future.

    Regards,
    Kartik.
