The requirement is to get the list of barcodes and its associated type , data ,etc. along with its positioning in a PDF.I am using open-source Apache PDFBox and Zxing Java based libraries for the implementation and not allowed to implement using any paid libraries.

The following response is being returned for barcode co-ordinates/position , which is beyond the range of PDF. Values such as Point: (4791.0, 589.5) and Point: (4791.0, 1001.5) which can't be plotted in a PDF. The barcode text and format is being correctly extracted using the following code.

Any idea on how to get the correct Barcode positions from the following code / any alternate source code ?

Output from the source code

Barcode text: Barcode format: QR_CODE Point: (4689.0, 3745.0) Point: (4689.0, 3569.0) Point: (4865.0, 3569.0) Point: (4841.0, 3721.0)

Barcode text: 28852 Barcode format: CODE_128 Point: (4791.0, 589.5) Point: (4791.0, 1001.5)

Barcode text: 08179018 Barcode format: UPC_E Point: (1500.5, 438.0) Point: (906.5, 438.0)

Barcode text: 147089001 Barcode format: CODE_128 Point: (4867.0, 1522.5) Point: (4867.0, 2072.5)

Barcode text: OPS Barcode format: CODE_128 Point: (4867.0, 2603.5) Point: (4867.0, 2947.5)
