Generate Aztec 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 an Aztec Code barcode, follow these steps:

  1. Create a GdPictureImaging object.
  2. Set the version of the barcode with the BarcodeAztecCodeVersion enumeration, and store it in a variable. Use the BarcodeAztecCodeVersionAuto member to let the engine determine the minimum version required to encode all input data.
  3. Compute the size of the barcode with the BarcodeAztecGetSize method of the GdPictureImaging object. This method takes the following parameters:
    • The data encoded in the barcode.
    • The version of the barcode.
    • The percentage of error correction. Set a value between 5 and 95. The recommended value is 23.
    • The number of modules considered quiet zone around the barcode.
    • The size of each module 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 BarcodeAztecWrite 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 version of the barcode.
    • The percentage of error correction. Set a value between 5 and 95. The recommended value is 23.
    • The number of modules considered quiet zone around the barcode.
    • 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 an Aztec Code barcode:

using GdPictureImaging gdpictureImaging = new GdPictureImaging();
// Set the version of the barcode.
BarcodeAztecCodeVersion version = BarcodeAztecCodeVersion.BarcodeAztecCodeVersionAuto;
// Compute the size of the barcode.
gdpictureImaging.BarcodeAztecGetSize("0123456789", ref version, 23, 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.BarcodeAztecWrite(imageID, "0123456789", ref version, 23, 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);
