Generate MaxiCode barcodes in C# .NET

Nutrient .NET SDK (formerly GdPicture.NET) enables you to generate one-dimensional (1D or linear) and two-dimensional (2D) barcodes.

Nutrient .NET SDK supports all 1D barcode formats and the following 2D barcode formats:

  • Aztec Code
  • Data Matrix
  • MaxiCode
  • Micro QR
  • PDF417
  • QR

To generate a MaxiCode barcode, follow the steps below:

  1. Create a GdPictureImaging object.
  2. Set the encoding mode of the barcode with the BarcodeMaxiCodeEncodingMode enumeration, and store it in a variable.
  3. Compute the size of the barcode with the BarcodeMaxiCodeGetSize method of the GdPictureImaging object. This method takes the following parameters:
    • The number of modules considered quiet zone around the barcode.
    • The distance between two modules on the same horizontal line expressed in pixels.
    • An output parameter that defines the width of the barcode.
    • An output parameter that defines the height of the barcode.
  4. Create an empty GdPicture image with the CreateNewGdPictureImage method of the GdPictureImaging object. This method takes the following parameters:
    • The width of the image in pixels.
    • The height of the image in pixels.
    • The bit depth of the image.
    • The background color of the image. Use the ARGB method of the GdPictureImaging object to specify the color with the ARGB standard. For example, for a white background, set gdpictureImaging.ARGB(255, 255, 255).
  5. Write the barcode to the empty image with the BarcodeMaxiCodeWrite method of the GdPictureImaging object. This method takes the following parameters:
    • The image ID of the newly created image.
    • The data encoded in the barcode.
    • The encoding mode.
    • The size of the quiet zone around the barcode in pixels.
    • The size of each module in pixels.
    • The distance between the left side of the image and the barcode in pixels.
    • The distance between the top side of the image and the barcode in pixels.
    • The angle of the barcode.
    • The color of the symbols on the barcode. Use the ARGB method of the GdPictureImaging object to specify the color with the ARGB standard. For example, for black, set gdpictureImaging.ARGB(0, 0, 0).
    • The background color of the barcode. Use the ARGB method of the GdPictureImaging object to specify the color with the ARGB standard. For example, for white, set gdpictureImaging.ARGB(255, 255, 255).
  6. Save the image as a PNG file with the SaveAsPNG method of the GdPictureImaging object.
  7. Release unnecessary resources.

The example below generates a MaxiCode barcode:

using GdPictureImaging gdpictureImaging = new GdPictureImaging();
// Set the encoding mode of the barcode.
BarcodeMaxiCodeEncodingMode encodingMode = BarcodeMaxiCodeEncodingMode.Mode5;
// Compute the size of the barcode.
gdpictureImaging.BarcodeMaxiCodeGetSize(4, 8, out int width, out int height);
// Create an empty GdPicture image.
int imageID = gdpictureImaging.CreateNewGdPictureImage(width, height, 32, gdpictureImaging.ARGB(255, 255, 255));
// Write the barcode to the empty image.
gdpictureImaging.BarcodeMaxiCodeWrite(imageID, "0123456789", encodingMode, 4, 8, 0, 0, 0, gdpictureImaging.ARGB(0, 0, 0), gdpictureImaging.ARGB(255, 255, 255));
// Save the image as a PNG file.
gdpictureImaging.SaveAsPNG(imageID, @"C:\temp\output.png");
// Release unnecessary resources.
gdpictureImaging.ReleaseGdPictureImage(imageID);
