PdfGraphics.DrawImage(Byte, PointF) Method
Draws the specified image using the byte array data at the specified location.
An array of bytes representing an image to draw.
A PointF structure that represents the image location.
This method renders an image with its original resolution (DPI).
To add an image to the page, you need to call one of the PdfGraphics.AddToPageForeground, PdfGraphics.AddToPageBackground, and PdfDocumentProcessor.RenderNewPage overload methods. Note that these methods accept DPI values as arguments.
The DPI values do not affect image quality and are used for coordinate transformation only (world coordinates to page coordinates). See the Coordinate Systems topic to learn more about the coordinate transformations.\
If you embed multi-page TIFF images with CCITT T.4 or CCITT T.6 compression to the document, the PdfDocumentProcessor draws the first page only.
The PdfGraphics will produce vector graphics for the EMF+ metafiles only. If a metafile contains more than GDI+ commands, it will be rasterized and rendered as a bitmap.
