# Reading 1D barcodes from images

This guide demonstrates how to read one-dimensional (1D) barcode values from an image.

Use this workflow when you need to:

- Extract product or shipment identifiers from barcode images

- Support inventory, checkout, or logistics pipelines

- Process one or more barcodes from a single file

## Implementation

The workflow loads an image, runs a barcode scan, and reads detected values:

```csharp

using GdPicture14;

LicenseManager licence = new LicenseManager();
licence.RegisterKEY(""); // Set a demo key

using GdPictureImaging imaging = new GdPictureImaging();
int imageId = imaging.CreateGdPictureImageFromFile(@"input_barcode_1d.png");
imaging.Barcode1DReaderDoScan(imageId);
int barcodesCount = imaging.Barcode1DReaderGetBarcodeCount();
string barcodeValue = imaging.Barcode1DReaderGetBarcodeValue(1);

```

## Supported barcode types

The SDK supports common 1D formats, including:

- Code 128

- Code 39

- UPC-A and UPC-E

- EAN-13 and EAN-8

- Code 93

- Interleaved 2 of 5

## Notes

- Use `Barcode1DReaderGetBarcodeCount()` to check how many barcodes the scan found.

- Use `Barcode1DReaderGetBarcodeValue(index)` to retrieve each barcode value by index.

- Add status checks in production code to handle image load and scan failures.

## Conclusion

This workflow scans an image for 1D barcodes and reads decoded values for downstream business logic.
