Does not work AutoRotateCenter (-1) in iPrintOptions := QP.PrintOptions(0, -1, ‘’);.

Always returns clockwise instead anticlockwise.

NormalizePage does not give result.

What's the problem?

Hi Nick,

perhaps it's better to post the piece of code where these functionality is used.

The value you're using is part of PrintOptions.

In iPrintOptions you'll get an integer value and this integer value you can use as last parameter in PrintDocument and then (processing PrintDocument) you'll see the affect.

If functionality like NormalizePage shall have permanent affect then you should save the file.

Hello, Ingo!

This is my snippet:

Delphi XE7, Win 10;

Delphi 7, Win XP;

Quick PDF Library 11.12 and 11.13

CustomPrinter := QP.NewCustomPrinter(ComboBox1.Text);

iPrintOptions := QP.PrintOptions(1, -1, '');

QP.SetupCustomPrinter(CustomPrinter, 1, Letter);

…

QP.PrintDocument(CustomPrinter, 1, QP.PageCount, iPrintOptions);

Always returns clockwise.

It from the ”Debenu Quick PDF Library 11.12 Reference Guide”:

AutoRotateCenter:

0 = Do not rotate pages automatically

1 = Rotate pages to fit on the output medium, and center on the page

-1 = Rotate pages to fit on the output medium, and center on the page

but rotate anticlockwise instead.

It from the ”Debenu Quick PDF Library 11.13 Dashboard (4.10)”:

/* Create a custom printer and specify your own settings */

// Load a sample file from the input folder

QP.LoadFromFile(GetInputFolder() + "01_Landscape.pdf", "");

// Create the custom printer

CustomPrinter = QP.NewCustomPrinter("Microsoft XPS Document Writer");

// Setup the settings for the customer printer

// Medium quality

QP.SetupCustomPrinter(CustomPrinter, 5, 2);

// Monochrome

QP.SetupCustomPrinter(CustomPrinter, 6, 1);

// Horizontal Duplex

QP.SetupCustomPrinter(CustomPrinter, 7, 3);

// Configure print options

iPrintOptions = QP.PrintOptions(0, -1, "Printing Sample");

// Print the current document to the default printing

// using the options as configured above

QP.PrintDocument(CustomPrinter, 1, 1, iPrintOptions);

Result of the same.

Thank you very much.

P.S.

Options with numbers:

QP.PrintDocument(CustomPrinter, 1, QP.PageCount, 115201); // 0 = OK!

QP.PrintDocument(CustomPrinter, 1, QP.PageCount, 115217); // 1 = OK!

QP.PrintDocument(CustomPrinter, 1, QP.PageCount, 115249); // -1 = 1. Why?

Thanks a lot!

Hi Nick,

did you do the three tests with the same document?

My idea:

If the document was initially created with RotatePage 180

and now there are PrintOptions with -1 then it can be rotated

to 90?

Try any editor and open the relevant pdf document...

search for "Rotate...". I think you'll find something?
