IKPrintCreateDC

This function creates a device context.

Parameters

Return Value

Returns the device context if successful. Returns null (0) if unsuccessful.

Explanation

The IKPrintCreateDC function creates a device context in one of three ways.

When the Mode parameter is 0:

The device context is created for the printer that has its name set in the PrinterName parameter.
The PrintFileName and DevMode are disabled.

When the Mode parameter is 1:

The device context is created for the printer that is listed in the file set in the PrintFileName parameter.
The PrinterName and DevMode are disabled.

When the Mode parameter is 2:

The device context is created from the handle of the DEVMODE structure that is set in the hDevMode parameter.
The PrinterName and PrintFileName are disabled.

To print with the default printer using the current settings, set the Mode parameter to 1 and in the PrintFileName parameter set, "Default".

When the device context is created and returned in the return value, the IKPrintStartDoc, IKPrintStartPage, IKPrintEndPage, IKPrintEndDoc functions can be used. The device context is freed using the IKPrintDeleteDC function.

As an extension to the PrintFileName, it is possible to set and save a other printer settings using the PrintFileName. Before executing the IKPrintCreateDC function, it is possible to save not only the file name but also the number of copies, the paper orientation, and the paper size (in that order) in the PrintFileName. The delimiter for the settings is a semicolon (;). Note: Enter a zero (0) into the settings that you do not want to change.

Orientation: The values in parentheses are the same as the constants used in WindowsAPI

1: Vertical (DMORIENT_PORTRAIT)            2: Horizontal (DMORIENT_LANDSCAPE)

PaperSize: The values in parentheses are the same as the constants used in WindowsAPI

1. Letter, 8.5 x 11 in (DMPAPER_LETTER)
2. Letter Small, 8.5 x 11 in (DMPAPER_LETTERSMALL)
3. Tabloid, 11 x 17 in (DMPAPER_TABLOID)
4. Ledger, 17 x 11 in (DMPAPER_LEDGER)
5. Legal, 8.5 x 14 in (DMPAPER_LEGAL)
6. Statement, 5.5 x 8.5 in (DMPAPER_STATEMENT)
7. Executive, 7.25 x 10.5 in (DMPAPER_EXECUTIVE)
8. A3, 297 x 420 mm (DMPAPER_A3)
9. A4, 210 x 297 mm (DMPAPER_A4)
10. A4 Small, 210 x 297 mm (DMPAPER_A4SMALL)
11. A5, 148 x 210 mm (DMPAPER_A5)
12. B4, 250 x 354 mm (DMPAPER_B4)
13. B5, 182 x 257 mm (DMPAPER_B5)

For paper sizes other than those listed above, please refer to the WindowsAPI reference for your development container.

Sample Code: Using a printer setting file (IKPrn.IK) to print (VisualBasic)

(1) Standard case

     PrintFileName = "C:\Test\IKPrint.IK"

(2) Using the extended functions of the printer setting file

     A) Number of copies= 3, Orientation = Horizontal, PaperSize = B5

         PrintFileName = "C:\Test\IKPrint.IK;3;2;13"

     B) Retrieve the number of copies and paper size from the printer file but the orientation to horizontal

         PrintFileName = "C:\Test\IKPrint.IK;0;2;0" or PrintFileName = "C:\Test\IKPrint.IK;0;2"

Sample Code: Using a printer setting file (IKPrn.IK) to print

In C++Builder

    HDC hDC;

    hDC = IKPrintCreateDC(NULL, "C:\\Test\\IKPrn.IK", NULL, 1);
    if (hDC == NULL) return;

    if (IKPrintStartDoc(hDC, Form1->Handle, "", "", "", "ImageKit Print Sample") != FALSE) {
        IKPrintStartPage(hDC);

        // Display image, draw text or shapes, etc.

        IKPrintEndPage(hDC);
        IKPrintEndDoc(hDC);
     }
     IKPrintDeleteDC(hDC);

In Delphi

    DC: HDC;

    DC := IKPrintCreateDC(nil, 'C:\Test\IKPrn.IK', 0, 1);
    if DC = 0 then Exit;
    if (IKPrintStartDoc(DC, Form1.Handle, '', '', '', 'ImageKit Print Sample') <> False) then
    begin
        IKPrintStartPage(DC);

        // Display image, draw text or shapes, etc.

        IKPrintEndPage(DC);
        IKPrintEndDoc(DC);
    end;
    IKPrintDeleteDC(DC);
