Could not detect barcode when scan resolution < 250dpi
Posted: Mon Sep 10, 2012 12:37 pm
Hi Guys,
I'm using GDPicture 9.0 and my business is scanning an image into system via scanner and detect barcode automatically on that image if it has. But the problem is barcode of image COULD NOT be detected if scan resolution is 100 - 150 dpi ( it works well at 250 - 1000 dpi ).
I tried again with very quality image ( printing resolution is 1200 dpi ) but the result is same as above.
*** Note :
1. When importing images from file, barcode always be detected well ( it is not affect by scan resolution )
Could you please let me know how could i detect barcode when scan resolution is at 100 - 150 dpi ?
Every helps are welcome.
