Leadtools Namespace : RasterColorSpace Class



Provides support for converting buffered image data from one color space to another.

Syntax

Visual Basic (Declaration) 
Public MustInherit NotInheritable Class RasterColorSpace
Visual Basic (Usage)Copy Code
Dim instance As RasterColorSpace
C# 
public static class RasterColorSpace
C++/CLI 
public ref class RasterColorSpace abstract sealed

Example

This example will load an image, resizes each line then saves the resized image back to disk.

Visual BasicCopy Code
Public Sub RasterColorSpaceExample()
 RasterCodecs.Startup()
 Dim codecs As RasterCodecs = New RasterCodecs()

 ' load an image
 Dim fileName As String = LeadtoolsExamples.Common.ImagesPath.Path + "Image1.cmp"
 Dim image As RasterImage = codecs.Load(fileName)

 ' Allocate the input buffer for 24-bit RGB data
 Dim inBuffer As Byte() = New Byte(image.Width * 3 - 1) {}

 ' Allocate the output buffer for 32-bit CMYK data
 Dim outBuffer As Byte() = New Byte(image.Width * 4 - 1) {}

 ' Get one row of data from the bitmap
 image.Access()
 image.GetRow(0, inBuffer, 0, image.BytesPerLine)
 image.Release()

 ' Convert the data from RGB in inBuffer to CMYK in outBuffer
 RasterColorSpace.Convert8(inBuffer, 0, outBuffer, 0, image.Width, RasterColorSpaceFormat8.Rgb, RasterColorSpaceFormat8.Cmyk)

 ' Cleanup
 image.Dispose()
 RasterCodecs.Shutdown()
