Hi all,
Please I build an application that should work at IPad, and I am using ZBar.
The image that contain the barcode is UIImage called TempUIImage, how could I use the ZBar to detect the value of the barcode and it's location.
Note: I don't want to preview the camera at all, because the TempUIImage is an UIImage that should be taken from another application.
Please Advise !!!
Regards,
