PreCompressedImageExists Method

Summary

Checks whether a Pre-compressed image exists in the server.

Syntax

C++

Leadtools.Dicom.Services.Datatypes.PreCompressedImageTypes PreCompressedImageExists(  
   string sopInstanceUID, 
   int imageWidth, 
   int imageHeight, 
   string mimeType, 
   int bitsPerPixel, 
   int qualityFactor 
)

Function PreCompressedImageExists( _ 
   ByVal sopInstanceUID As String, _ 
   ByVal imageWidth As Integer, _ 
   ByVal imageHeight As Integer, _ 
   ByVal mimeType As String, _ 
   ByVal bitsPerPixel As Integer, _ 
   ByVal qualityFactor As Integer _ 
) As Leadtools.Dicom.Services.Datatypes.PreCompressedImageTypes

Leadtools.Dicom.Services.Datatypes.PreCompressedImageTypes PreCompressedImageExists(  
   String^ sopInstanceUID, 
   int imageWidth, 
   int imageHeight, 
   String^ mimeType, 
   int bitsPerPixel, 
   int qualityFactor 
)

Parameters

sopInstanceUID
A System.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 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
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.

Remarks

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

Example

For an example, refer to the Medical Web Viewer demo, located in DICOMServicescs.csproj project.
