Parameters

sopInstanceUID

A String representing the SOP Instance UID of the DICOM object.

imageWidth

The width, in pixels, of the image.

imageHeight

The Height, in pixels, of the image.

mimeType

A String representing the file format and compression of the image. Check the SupportedImageFormat class for supported file formats and compression.

bitsPerPixel

Image's pixel depth. Note that not all bits per pixel are available to all image formats. If bitsPerPixel is 0, the image will be stored using the original or closet bits/pixel value supported by that format.

qualityFactor

The quality factor (Q factor) is a number that determines the degree of loss in the compression process. Use 0 for Lossless compression or you can set a value from 2 to 255, where 2 is the highest quality and 255 is the most compression.

This method is to support the plug-ins architecture on the server side. It's not intended to be exposed on the WCF service.
