AddImageFromBitmap(Bitmap,PdfAdvancedImageCompression) Method

In This Topic

Adds an image resource and then subsequently draws this image onto a newly created page within the currently loaded PDF document. You can 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.

)

Parameters

bitmap: A Bitmap object specifying an image resource to be added into the current document.
AdvancedCompression: 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.
