GdPicture.NET.14.API
GdPicture14 Namespace / GdPicturePDF Class / AddImageFromGdPictureImage Method / AddImageFromGdPictureImage(Int32,PdfAdvancedImageCompression) Method
The unique image identifier of the GdPictureImage object representing the required image. You need to add the image resource into the currently loaded PDF document, for example, using methods of the GdPictureImaging class, whose returned value is the unique image identifier.
A member of the PdfAdvancedImageCompression enumeration. Specifies the advanced compression mechanism.
Example





In This Topic
AddImageFromGdPictureImage(Int32,PdfAdvancedImageCompression) Method
In This Topic
Adds an image resource, specified by its unique image identifier, and then subsequently draws this image onto a newly created page within the currently loaded PDF document. You can obtain this identifier, for example, using methods of the GdPictureImaging class when you create the image resource using an object of the type GdPictureImage. You can also specify an advanced compression mechanism such as color detection or mixed raster content (MRC) compression when drawing an image. The dimensions of the newly added page are the same as the original dimensions of the inserted image and the page is inserted as the last page in the document.

Parameters

ImageID
The unique image identifier of the GdPictureImage object representing the required image. You need to add the image resource into the currently loaded PDF document, for example, using methods of the GdPictureImaging class, whose returned value is the unique image identifier.
AvancedCompression
A member of the PdfAdvancedImageCompression enumeration. Specifies the advanced compression mechanism.

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 the newly created page is always inserted as the last page in the loaded document.
