ConvertDirect(ConversionColorFormat,ConversionColorFormat,byte[],int,byte[],int,int,int,int,int) Method

Summary

Converts image data in a managed buffer from one color conversion model directly to another, using built-in algorithms.

Syntax
C#
C++
public static void ConvertDirect( 
   ConversionColorFormat srcFormat, 
   ConversionColorFormat destFormat, 
   byte[] srcBuffer, 
   int srcBufferOffset, 
   byte[] destBuffer, 
   int destBufferOffset, 
   int width, 
   int height, 
   int inAlign, 
   int outAlign 
) 
vb[VB Syntax] 
Public Shared Sub ConvertDirect( 
   ByVal _srcFormat_ As ConversionColorFormat, 
   ByVal _destFormat_ As ConversionColorFormat, 
   ByVal _srcBuffer_() As Byte, 
   ByVal _srcBufferOffset_ As Integer,

public:  
   static void ConvertDirect( 
       ConversionColorFormat^ srcFormat, 
      ConversionColorFormat^ destFormat, 
      array<Byte>^ srcBuffer, 
      int srcBufferOffset, 
      array<Byte>^ destBuffer, 
      int destBufferOffset, 
      int width, 
      int height, 
      int inAlign, 
      int outAlign 
   ) 

Parameters

srcFormat

Format of the input data.

destFormat

Format of the output data.

srcBuffer

A pointer to the buffer containing the input data.

srcBufferOffset

Offset to the first byte of the srcBuffer data buffer.

destBuffer

A pointer to the buffer containing the output data.

destBufferOffset

Offset to the first byte of the destBuffer data buffer.

width

Width of pixels to be processed.

height

Height of pixels to be processed.

inAlign

Each scanline in the input buffer is a multiple of inAlign bytes.

outAlign

Each scanline in the output buffer is a multiple of outAlign bytes.

Remarks

There is no need to call the Start and Stop methods to initialize or stop the conversion engine.

Converting from any color space to YCCK color space is currently not supported.

For more information about Alignment Parameters, refer to Alignment Parameters.

To convert to the Yp41 type the input buffer length must be a multiple of 8.

Example

This example will convert a CMYK color to an RGB color, using the ConvertDirect static method.

C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ColorConversion; 
 
 
public void ConvertDirectExample() 
{ 
   // StartUp the ColorConversion. 
   RasterColorConverterEngine.Startup(); 
 
   // Rgb and Cmyk color buffer arrays 
   byte[] rgbColor = new byte[3]; 
   byte[] cmykColor = { 100, 100, 100, 100 }; 
 
   try 
   { 
      // direct conversion using built in options 
      // The srcBufferOffset parameter is an offset to the start byte of the data in the source buffer. 
      // For example, if the image data started at byte 5, then this variable should = 5. 
      // in our case here, the image data starts at byte 0. 
      // The same thing applies to destBufferOffset. 
 
      // The cmykColor is a bytes array, you can pass it directly like this example, 
      // or you can pass an IntPtr pointer to the buffer. 
      // The same thing applies for rgbColor. 
      RasterColorConverterEngine.ConvertDirect( 
         ConversionColorFormat.Cmyk, 
         ConversionColorFormat.Rgb, 
         cmykColor, 
         0, 
         rgbColor, 
         0, 
         1, 
         1, 
         0, 
         0); 
   } 
   catch (Exception ex) 
   { 
      MessageBox.Show(ex.Message); 
   } 
 
   //. 
   //. 
   //. 
   // use rgbColor as you need. 
 
   // Shutdown the ColorConversion. 
   RasterColorConverterEngine.Shutdown(); 
}
