Our Goal is to read Bar Codes from Drivers Licenses. All images will be coming from a URL and I convert them to a stream. BUT reader always return a null. is there something wrong with my code?
please see this an example of PDF 417 barcode.
The main problem with this barcode consists in low resolution and high blur. The minimal sizes of start and stop pdf417 symbols are 17 and 18 pixels relatively. This barcode image has 8 pixels in the start pattern area, which connects bars one to other and makes recognition impossible.
The solution could be a scanning the barcode with 300dpi or higher resolution (300dpi is enough).
We need 300 dpi image to recognize this barcode.
