delphi

procedure EnumPagesAsImages(const APageIndexes: array of Integer; AGraphicClass: TGraphicClass; ADrawBackground: Boolean; ACallBackProc: TdxEnumPagesAsImagesProc; ACallBackData: Pointer; AProgressData: Pointer; APrepareData: Pointer; AReportLink: TBasedxReportLink = nil);

Parameters

Name	Type
APageIndexes	Integer
AGraphicClass	TGraphicClass
ADrawBackground	Boolean
ACallBackProc	TdxEnumPagesAsImagesProc
ACallBackData	Pointer
AProgressData	Pointer
APrepareData	Pointer
AReportLink	TBasedxReportLink

Remarks

The EnumPagesAsImages method is called within the SavePagesAsImagesToDisk method to obtain report pages for the report link specified by the AReportLink parameter in graphic representation.

The APageIndexes parameter specifies absolute indexes of report pages used in specific events.

The AGraphicClass parameter specifies the image type.

Set the ADrawBackground parameter to True to draw the original background within an image.

The ACallBackData, AProgressData and APrepareData parameters determine pointers to arbitrary data which is used in the TdxEnumPagesAsImagesProc procedure, as well as in the OnExportProgress and OnExportPrepareGraphic events.

The TdxEnumPagesAsImagesProc procedure includes the following parameters:

Parameter	Description
AComponentPrinter	Determines the component printer which sends data.
AReportLink	Determines the report link whose report is being converted.
AIndex	Determines the zero-based index of the exported report page among other pages.
APageIndex	Determines the absolute index of the current page within a report, passed via the APageIndexes parameter of the EnumPagesAsImages method.
AGraphic	Specifies the image created for a specific page.
AData	Contains the pointer to additional arbitrary data which is determined by the ACallBackData parameter of the EnumPagesAsImages method.
AContinue	Set this parameter to True to continue converting report pages to graphic images or to False , to break all operations.
