SetBulkData(RasterImage,int) Method (original) (raw)
Summary
Sets the BulkData with a RasterImage and a quality factor.
Syntax
Parameters
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.

// You can change the TransferSyntax here to any valid TransferSyntax
// Setting the TransferSyntax ElementValue to empty defaults the transfer syntax to Explicit VR Little Endian
//if (elementData.Tag == DicomTag.TransferSyntaxUID)

// elementData.ElementValue = string.Empty;
//}
if (elementData.Encoding == ElementDataType.BulkData)

// If elementData.Encoding is ElementDataType.BulkData, then the BulkDataUri is returned in elementData.ElementValue
Console.WriteLine($"BulkDataUri: {elementData.ElementValue}");
// Set the bulk data: four ways to do it
//
string rawImagePath = Path.Combine(LEAD_VARS.ImagesDir, "image2.jpg");
string pngImagePath = Path.Combine(LEAD_VARS.ImagesDir, "PngImage.png");
// Method 1: Setting the [BulkData] property
using (FileStream fs = new FileStream(rawImagePath, FileMode.Open))
{
using (MemoryStream ms = new MemoryStream())
{
fs.CopyTo(ms);
elementData.BulkData = ms.ToArray();
}
}
// Method 2: Calling SetBulkData() with a byte array
using (FileStream fs = new FileStream(rawImagePath, FileMode.Open))
{
using (MemoryStream ms = new MemoryStream())
{
fs.CopyTo(ms);
elementData.SetBulkData(ms.ToArray());
}
}
// Method 3
// Set the bulk data using a RasterImage
using (RasterCodecs codecs = new RasterCodecs())
{
using (Leadtools.RasterImage image = codecs.Load(pngImagePath))
{
// The second argument is optional and specifies the QFactor
elementData.SetBulkData(image, 2);
}
}
// Method 4
// In this example(image2.dcm) it is raw jpeg data
// For uncompressed DICOM data, pass the raw uncompressedData
using (FileStream fs = new FileStream(rawImagePath, FileMode.Open))
{
elementData.SetBulkData(fs);
}
