Syntax

Visual Basic
C#

'Declaration
 
Public Function OriginalPixelData( _
   ByVal Frame As System.Integer, _
   ByRef TransferSyntax As System.String _
) As System.Array

public System.Array OriginalPixelData( 
   System.int Frame,
   out System.string TransferSyntax
)

Parameters

Frame: Frame number to extract
TransferSyntax: TransferSyntax of the compressed data

Return Value

Original pixel data (Compressed or Uncompressed)

Example

DicomDataSet ds = new DicomDataSet("Dataset.dcm");
int frame = 10;
string transferSyntax;
                    
var pixelData = ds.OriginalPixelData(frame, out transferSyntax);
                    
if (pixelData is byte[] byteArray)
{
    File.WriteAllBytes(@"D:\Temp\frame10_pixeldata.bin", byteArray);
    Console.WriteLine($"Frame {frame} pixel data extracted ({byteArray.Length} bytes), TS = {transferSyntax}");
}
else if (pixelData is ushort[] ushortArray)
{
    byte[] raw = new byte[ushortArray.Length * 2];
    Buffer.BlockCopy(ushortArray, 0, raw, 0, raw.Length);
    File.WriteAllBytes(@"D:\Temp\frame10_pixeldata_u16.bin", raw);
    Console.WriteLine($"Frame {frame} 16-bit pixel data extracted ({raw.Length} bytes), TS = {transferSyntax}");
}
