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:
