Parameters

sopInstanceUID
The SOP Instance UID of the DICOM object.

frameNumber
A 1 based number of the frame you want to retrieve from the image. Pass 0 to get a representative frame and -1 to get the full image with all frames.

imageWidth
The width, in pixels, of the image. The returned image can have a different width(to preserve scale ratio). Pass 0 to keep the original width.

imageHeight
The height, in pixels, of the image. The returned image can have a different height(to preserve scale ratio).

mimeType
A System.String representing the file format and compression of the image. Check the Leadtools.Dicom.Services.DataTypes.SupportedImageFormat class for supported file formats and compression.

bitsPerPixel
Resulting 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 closest 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.

extraData
User custom data.

Return Value

A buffer containing the image file (e.g. JPEG, TIFF).
