Example

This example will create an array of RasterColor containing 256 shades of gray.

Java

using Leadtools; 
 
 
public void FromRgbExample() 
{ 
	RasterColor[] colors = new RasterColor[RasterColor.MaximumComponent - RasterColor.MinimumComponent + 1]; 
	for (int i = RasterColor.MinimumComponent; i < RasterColor.MaximumComponent; i++) 
	{ 
		colors[i] = RasterColor.FromRgb(i); 
	} 
 
	for (int i = RasterColor.MinimumComponent; i < RasterColor.MaximumComponent; i++) 
	{ 
		Assert.IsTrue(colors[i].ToRgb() == i); 
	} 
}
