RasterColorSpace Class (original) (raw)

Summary

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

Syntax

C#

Objective-C

C++/CLI

Python

public static class RasterColorSpace 
@interface LTRasterColorSpace : NSObject 
public ref class RasterColorSpace abstract sealed  

Example

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

using Leadtools; using Leadtools.Codecs; public void RasterColorSpaceExample() { string fileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1.cmp"); using (RasterCodecs codecs = new RasterCodecs()) { // load an image using (RasterImage image = codecs.Load(fileName)) { // Allocate the input buffer for 24-bit RGB data byte[] inBuffer = new byte[image.Width * 3]; Assert.IsTrue(inBuffer.Length == image.BytesPerLine); // Allocate the output buffer for 32-bit CMYK data byte[] outBuffer = new byte[image.Width * 4]; // 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); } } } static class LEAD_VARS { public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images"; }
