#100 does not recognize code128 without preprocessing

[Anonymous]

I've used zbarimg to extract bar-code (code128) from the JPEG photos taken with DSLR camera. Version 0.8 works fine, but a few weeks ago we updated server and got latest zbarimg (0.10). Now zbarimg can't extract bar code from most of images (about 98%).

I have found that extra processing with ImageMagick

convert image.jpg -colorspace gray -white-threashold 23% processed.jpg

helps zbarimg to recognize bar-code.

So, I just wish to know if zbarimg became more strict for used images or it's some bug?

Thank you for the great tool.

I've attached test image to the issue. Here is system details:

There was misprint in preprocessing command, here is correct one:

convert image.jpg -colorspace gray -white-threshold 23% processed.jpg
