EnumResolutions (ImageKit Control/PrintDraw Method)

This method retrieves a list of supported resolutions for the printer designated by the printer name.

[C++Builder] [ int = ]imagekitcontrolname->PrintDraw->EnumResolutions(TPoint * Resolutions, const int Resolutions_Size)

[Delphi] [ Integer = ]imagekitcontrolname.PrintDraw.EnumResolutions(var Resolutions: array of TPoint)

Parameters

Name	Explanation
Resolutions	An array containing the list of retrieved resolutions In C++Builder, pass Resolutions count - 1 into Resolutions_Size

Return Value

Returns the number of retrieved items. Returns 0 if unsuccessful.

Explanation

The EnumResolutions method retrieves a list of supported resolutions for the printer designated by the printer name. If you need to know the number of elements in the array, the GetArrayNum method can be used to retrieve this. The Resolutions parametercontains the retrieved resolution values in units of dots per inch (dpi)

Sample code:

C++Builder

int Size;
TPoint *Resolutions;

VImageKit1->PrintDraw->PrinterName = "EPSON LP-8200C";
Size = VImageKit1->PrintDraw->GetArrayNum(vikPrinterResolution);
if (Size < 1) return;
Resolutions = new TPoint[Size];
__try {
   VImageKit1->PrintDraw->EnumResolutions(Resolutions, Size - 1);
   // do stuff here
   ********************
} __finally {
    delete[] Resolutions;
}

In Delphi

Size: Integer;
Resolutions: array of TPoint;

VImageKit1.PrintDraw.PrinterName := 'EPSON LP-8200C';
Size := VImageKit1.PrintDraw.GetArrayNum(vikPrinterResolution);
if Size < 1 then Exit;
SetLength(Resolutions, Size);
VImageKit1.PrintDraw.EnumResolutions(Resolutions);
// do stuff here
********************

Differences between the ImageKit7/8/9/10

The XResolutions, YResolutions has been changed to type TPoint.
In C++Builder it is necessary to pass in the count of the Resolutions.
