The image resource name of the required image as a string.

You can obtain this name using one of these methods: %AddImageFromBitmap(Bitmap, bool, bool)% , GdPicturePDF.AddImageFromGdPictureImage, GdPicturePDF.GetPageImageResName or any of the AddJpegImageFrom...() methods. For further assistance, please see the Images section of the GdPicturePDF class in the Reference Guide.

The horizontal (X) coordinate of the bottom left point of the destination area, where the image is to be drawn, expressed in the current units specified by the SetMeasurementUnit method, related to the currently selected page.
The vertical (Y) coordinate of the bottom left point of the destination area, where the image is to be drawn, expressed in the current units specified by the SetMeasurementUnit method, related to the currently selected page.
The width of the destination area, expressed in the current units specified by the SetMeasurementUnit method.
The height of the destination area, expressed in the current units specified by the SetMeasurementUnit method.

DrawImage Method (GdPicturePDF)

In This Topic
Draws an image, specified by its resource name, onto the exactly defined area of the currently selected page of the loaded PDF document. The image already needs to be included in the current document as a resource using one of the AddImage... methods().

The coordinates and the dimensions of the destination area need to be set in the current units defined in the PDF document, related to the actual page, where the required image is to be drawn. You can use the GdPicturePDF.GetMeasurementUnit method to determine the currently defined units and you can use the GdPicturePDF.SetMeasurementUnit method to reset the units according to your preference.

Parameters

ImageResName
The image resource name of the required image as a string.

You can obtain this name using one of these methods: %AddImageFromBitmap(Bitmap, bool, bool)% , GdPicturePDF.AddImageFromGdPictureImage, GdPicturePDF.GetPageImageResName or any of the AddJpegImageFrom...() methods. For further assistance, please see the Images section of the GdPicturePDF class in the Reference Guide.

DstX
The horizontal (X) coordinate of the bottom left point of the destination area, where the image is to be drawn, expressed in the current units specified by the SetMeasurementUnit method, related to the currently selected page.
DstY
The vertical (Y) coordinate of the bottom left point of the destination area, where the image is to be drawn, expressed in the current units specified by the SetMeasurementUnit method, related to the currently selected page.
Width
The width of the destination area, expressed in the current units specified by the SetMeasurementUnit method.
Height
The height of the destination area, expressed in the current units specified by the SetMeasurementUnit method.

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.

Just to remind you that if the image to draw is a Mask Image, you should define the color for non-stroking operations by using the GdPicturePDF.SetFillColor method.

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.

We also recommend to take advantage of the GdPictureImaging class and its methods for further manipulation with images.

Example
These examples show you how to draw an image loaded from different resources using different methods - the first image is loaded from the external file and the second image is loaded from the current PDF document.
How to draw a jpeg image, loaded from the external file, onto the first page of the newly created PDF document twice, side by side, within the two same-sized areas.
