Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Barcode; 
using Leadtools.ImageProcessing; 
 
public void BarcodeExceptionCode_Example() 
{ 
	// Example of values passed by the user for the barcode width and height 
	int barcodeWidth = 30; 
	int barcodeHeight = 60; 
 
	// These values are too small to write a UPCA barcode and will throw an exception below 
 
	// Create a Barcode engine 
	BarcodeEngine engine = new BarcodeEngine(); 
 
	// Get the Barcode writer 
	BarcodeWriter writer = engine.Writer; 
 
	// Create an image 
	using (RasterImage image = RasterImage.Create(1000, 1000, 1, 300, RasterColor.FromKnownColor(RasterKnownColor.White))) 
	{ 
		// Create the barcode 
		BarcodeData barcode = BarcodeData.CreateDefaultBarcodeData(BarcodeSymbology.UPCA); 
		barcode.Bounds = new LeadRect(0, 0, barcodeWidth, barcodeHeight); 
 
		// Try to write it, this will throw an exception if the barcode is too small 
		try 
		{ 
			writer.WriteBarcode(image, barcode, null); 
		} 
		catch (BarcodeException ex) 
		{ 
			// Show the error message, should be BarcodeExceptionCode.InvalidWidth 
			Console.WriteLine(ex.Code); 
			Debug.Assert(ex.Code == BarcodeExceptionCode.InvalidWidth); 
		}
