GdPicture.NET.14
GdPicture14 Namespace / GdPicturePDF Class / AddImageFromGdPictureImage Method / AddImageFromGdPictureImage(Int32,Boolean,Boolean) 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.
Applicable only for 1 bit per pixel images. Indicates, whether the inserted image shall be treated as an image mask (or stencil mask). The recommended default value is false.
Set this parameter to true if you want to draw an image directly, otherwise set it to false.

If positive, then the new page is added into the current document as the last page and the image is drawn on its whole surface.

Example





In This Topic
AddImageFromGdPictureImage(Int32,Boolean,Boolean) Method
In This Topic
Adds an image resource, specified by its unique image identifier, to the currently loaded PDF document according to what you have specified. 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. Then you can either draw the image directly using this method or you can draw it later using the returned image resource name.

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.
ImageMask
Applicable only for 1 bit per pixel images. Indicates, whether the inserted image shall be treated as an image mask (or stencil mask). The recommended default value is false.
DrawImage
Set this parameter to true if you want to draw an image directly, otherwise set it to false.

If positive, then the new page is added into the current document as the last page and the image is drawn on its whole surface.

Return Value

Returns a name of the newly inserted image resource strictly bounded to the currently loaded PDF document. The GdPicturePDF.GetStat method can be subsequently used to determine if this method has been successful.

This name can be subsequently used with the GdPicturePDF.DrawImage method to draw an image onto the page.

Remarks
This method is only allowed for use with non-encrypted documents.

It is recommend to use the GdPicturePDF.GetStat method to identify the specific reason for the method's failure, if any.

Just to remind you, that the newly created page is inserted as the last page in the loaded document if you draw the image immediately.
