Scanning outside of yellow borders

[kostyabakay]

I have this trouble on devices with good camera. Is it the bug or some feature? Because I need scanning only in yellow borders.

[kostyabakay]

I solved my problem by creating class which extends ZBarScannerView and have the same realization, except one line of code:
var14.setCrop(0, height / 3, width, height / 3);
This question was very useful. Please modify your library for this problem.

Hi, I wanted to do this too and didn't think it would be that simple to do so I gave up. Does it make the scan results more accurate? Could you post the code of the whole class so that it's easier to visualize where you add that line?
Thanks :)

Yes, it becomes more accurate. My own class is copy ZBarScannerView except one line of code and this class extends ZBarScannerView. Please find this fragment in class and you will understand. Here is fragment of code with my one line:
Image var14 = new Image(width, height, "Y800");
var14.setData(data);
// setCrop() parameters: left, top, width, height
// http://stackoverflow.com/questions/18918211/how-to-change-area-of-scan-zbar
var14.setCrop(0, height / 3, width, height / 3); // Set scanning for the yellow borders
result = this.mScanner.scanImage(var14);

This setCrop method is very uncomfortable, so I hope the developer of this library will add this feature.

Thanks a lot!

Has this Library been updated to support this request without having to extend the ZBarScannerView yet?

That helped a lot, imho, it is worth to be included into the lib.
Thanks a lot, @kostyabakay!

@GoltsevEugene you are welcome :)
