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); 
		} 
	}
