The page number of the page, which content is to be drawn. This parameter is without any restrictions, the source page is selected by use of the SelectPage method, so all there mentioned details remain in effect.
The horizontal (X) coordinate of the bottom left point of the destination area, where the page content is to be drawn, expressed in the current units used in the destination PDF document, related to the currently selected page.
The vertical (Y) coordinate of the bottom left point of the destination area, where the page content is to be drawn, expressed in the current units used in the destination PDF document, related to the currently selected page.
The width of the destination area, expressed in the current units used in the destination PDF document.
The height of the destination area, expressed in the current units used in the destination PDF document.

DrawPage Method (GdPicturePDF)

In This Topic
Draws content of the page, specified by its page number, from a source PDF document, onto the exactly defined area of the currently selected page of the destination PDF document. The coordinates and the dimensions of the destination area need to be set in the current units defined in the destination PDF document, related to the actual page, where the content of the source page is to be drawn.

You can use the GetMeasurementUnit method to determine the currently defined units and you can use the SetMeasurementUnit method to reset the units according to your preference.

Parameters

SrcPDF
The source PDF document, which contains the source page to draw.
SrcPage
The page number of the page, which content is to be drawn. This parameter is without any restrictions, the source page is selected by use of the SelectPage method, so all there mentioned details remain in effect.
DstX
The horizontal (X) coordinate of the bottom left point of the destination area, where the page content is to be drawn, expressed in the current units used in the destination PDF document, related to the currently selected page.
DstY
The vertical (Y) coordinate of the bottom left point of the destination area, where the page content is to be drawn, expressed in the current units used in the destination PDF document, related to the currently selected page.
DstWidth
The width of the destination area, expressed in the current units used in the destination PDF document.
DstHeight
The height of the destination area, expressed in the current units used in the destination PDF document.

Return Value

A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK.

We strongly recommend always checking this status first.

Remarks
This method is only allowed for use with non-encrypted documents, both the source and the destination one.

Be aware that DstX and DstY parameters are fixly determined as the coordinates of the bottom left point of the destination area on the actual page.

This method requires the Document Editor component to run.

Example
How to draw content of the first page of the source PDF document onto the first page of the destination PDF document twice, side by side, within the two same-sized areas.
