Shutdown Method

Summary

Releases all the data used to start the Color Conversion toolkit.

Syntax

C++/CLI

Python

public static void Shutdown()

public: 
static void Shutdown();

def Shutdown(self):

Remarks

This static method must be called when the ColorConversion toolkit is no longer to be used, usually before your application shuts down.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ColorConversion; 
 
using Leadtools.ImageProcessing; 
 
public void StartupExample() 
{ 
   // StartUp the ColorConversion.  
   RasterColorConverterEngine.Startup(); 
 
   // Input file name  
   string inputFileName = Path.Combine(LEAD_VARS.ImagesDir, "image1.cmp"); 
 
   // Load the input image as Bgr 
   using (RasterCodecs codecs = new RasterCodecs()) 
   using (RasterImage bgrImage = codecs.Load(inputFileName, 24, CodecsLoadByteOrder.Bgr, 1, 1)) 
   { 
      // BGR buffer  
      byte[] bgrBuffer = new byte[bgrImage.BytesPerLine * bgrImage.Height]; 
      bgrImage.Access(); 
      bgrImage.GetRow(0, bgrBuffer, 0, bgrImage.BytesPerLine * bgrImage.Height); 
      bgrImage.Release(); 
 
      // CMYK buffer 
      byte[] cmykBuffer = new byte[bgrImage.Height * bgrImage.Width * 4]; 
 
      // Start the color conversion  
      RasterColorConverterEngine rasterColorConverterEngine = new RasterColorConverterEngine(); 
      rasterColorConverterEngine.Start(ConversionColorFormat.Bgr, ConversionColorFormat.Cmyk, null); 
      rasterColorConverterEngine.Convert(bgrBuffer, // input buffer  
         0, // offset from the beginning of the source buffer  
         cmykBuffer, // output buffer  
         0, // offset from the beginning of the destination buffer  
         bgrImage.Width, // pixels width  
         bgrImage.Height, // pixels height  
         bgrImage.BytesPerLine - (bgrImage.Width * (bgrImage.BitsPerPixel / 8)), // Scanline alignment for input buffer 
         0); // Scanline alignment for output buffer 
      rasterColorConverterEngine.Stop(); 
   } 
 
   // Shutdown the ColorConversion.  
   RasterColorConverterEngine.Shutdown();
