Barcode Activities

Used the bar code facility to process PDF files that had 4 bar codes on a page.

We have achieved a 90% recognition rate.

Found that PDF to image extraction had to be at 300 dpi (no higher resolution available).

Used the DeSpeckle and Contrast activities to make some marginal gains.

Experience showed that the failures from a procesing perspective were that the bar code process would get 3 out of the 4 bar codes, which left the document having to go for manual review.

The cover sheets with the bar codes are internally generated by the same process, so difficult to explain why scanning and recognition are not getting closer to 100%.

- Work very well on hight quality barcode. I personaly prefer using ZBar in python and then get the result on UiPath.

Works good. Better to have property for encoding. - Both encoding and decoding barcode work good. I suppose better to have property for character encoding because sometimes we use non UTF-8 encoding barcode. (CP932/Shift-JIS is often used in Japan. )
