SetBulkData(RasterImage,int) Method

Summary

Sets the BulkData with a RasterImage and a quality factor.

Syntax

C++/CLI

public void SetBulkData( 
   RasterImage image, 
   int QualityFactor 
)

public:  
   void SetBulkData( 
      RasterImage^ image, 
      Int32 QualityFactor 
   )

Parameters

image

A RasterImage that is converted to BulkData.

QualityFactor

A value indicating the quality factor (2..255) of the BulkData.

Remarks

There are four ways to modify the BulkData:

Setting the BulkData property
Calling [SetBulkData(byte[])] with a byte array
Calling SetBulkData(RasterImage,int) with a RasterImage and a quality factor
Calling SetBulkData(Stream) with Stream

When setting the BulkData using (3) SetBulkData(RasterImage,int), a quality factor is specified from 2 to 255 where 2 is the highest quality, and 255 is the lowest quality.
