Example
using Leadtools;
using Leadtools.Codecs;
using Leadtools.Barcode;
using Leadtools.ImageProcessing;
public void BarcodeWriter_Example()
{
// Create a directory to store the images we will create
string outDir = Path.Combine(LEAD_VARS.ImagesDir, "MyBarcodes");

{
Directory.Delete(outDir, true);
}

// Create a Barcode engine

// Get the Barcode writer
BarcodeWriter writer = engine.Writer;
// All 1D options have the UseXModule set to false by default, we need to set it to true
// so we can calculate the default size. We will change the default options so we can
// pass null to CalculateBarcodeDataBounds and WriteBarcode below
// For all Standard 1D

oneDWriteOptions.UseXModule = true;
// All GS1 Databar Stacked
GS1DatabarStackedBarcodeWriteOptions gs1DatabarStackedWriteOptions = writer.GetDefaultOptions(BarcodeSymbology.GS1DatabarStacked) as GS1DatabarStackedBarcodeWriteOptions;
gs1DatabarStackedWriteOptions.UseXModule = true;
// Patch Code
PatchCodeBarcodeWriteOptions patchCodeWriteOptions = writer.GetDefaultOptions(BarcodeSymbology.PatchCode) as PatchCodeBarcodeWriteOptions;
patchCodeWriteOptions.UseXModule = true;
// All PostNet/Planet
PostNetPlanetBarcodeWriteOptions postNetPlanetWriteOptions = writer.GetDefaultOptions(BarcodeSymbology.PostNet) as PostNetPlanetBarcodeWriteOptions;
postNetPlanetWriteOptions.UseXModule = true;
// We will use this object to save files

// Calculate its size with default options
writer.CalculateBarcodeDataBounds(LeadRect.Empty, resolution, resolution, data, null);
// Create an image to write the data to
LeadRect pixels = data.Bounds;
using (RasterImage image = RasterImage.Create(pixels.Width, pixels.Height, 1, resolution, RasterColor.FromKnownColor(RasterKnownColor.White)))
{
// Write the barcode with default options

// Save it
