Image apparently not recognized

[mcondarelli]

I have the following, apparently good, image:

It should be a i25 code, but:

mcon@cinderella:~/Work/OkCash/Stampante_marche/zbar$ zbarimg/zbarimg -d ../mark2.jpg 
scanned 0 barcode symbols from 1 images in 0.01 seconds


WARNING: barcode data was not detected in some image(s)
Things to check:
  - is the barcode type supported? Currently supported symbologies are:
	. EAN/UPC (EAN-13, EAN-8, EAN-2, EAN-5, UPC-A, UPC-E, ISBN-10, ISBN-13)
	. DataBar, DataBar Expanded
	. Code 128
	. Code 93
	. Code 39
	. Codabar
	. Interleaved 2 of 5
	. QR code
	. SQ code
  - is the barcode large enough in the image?
  - is the barcode mostly in focus?
  - is there sufficient contrast/illumination?
  - If the symbol is split in several barcodes, are they combined in one image?
  - Did you enable the barcode type?
    some EAN/UPC codes are disabled by default. To enable all, use:
    $ zbarimg -S*.enable <files>
    Please also notice that some variants take precedence over others.
    Due to that, if you want, for example, ISBN-10, you should do:
    $ zbarimg -Sisbn10.enable <files>

I tried both Debian standard package and self-built from git master with identical results.
I am not a barcode expert and thus I cannot divine what's going wrong.
I see similar questions are generally ignored in this forum, if I'm trespassing somehow
please redirect me to a "proper place".

Many Thanks in Advance
