AddJpegImageFromStream(Stream,Byte[]) Method

In This Topic
Creates an image resource directly from your JPEG image file without the need of lossy encoding and decoding process including option to provide ICC profile data. The image resource is subsequently added into the currently loaded PDF document. You can use this resource straightforward, for example, with the DrawImage method. This process allows you to easily draw an image from your JPEG file onto a page within the currently loaded PDF document.

Return Value

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

This name can be subsequently used with the DrawImage method to draw an image onto the page. For the correct usage please see the example below.

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

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