This program extracts QR codes from images in a specified directory and outputs the results to an Excel workbook.
The program follows these steps:
- Initialize the program with the directory of images and the name of the output Excel file.
- Process all images in the directory with the
QRCodeExtractorclass. - Divide the results into successful and failed extractions.
- Initialize the
ExcelWorkbookCreatorclass with the successful and failed extractions and the name of the output Excel file. - Create an Excel workbook with two sheets: "Successful Extractions" and "Failed Extractions".
- Populate the sheets with the respective extraction results.
- Apply styles and formatting to the workbook.
- Save the workbook to the output Excel file.
