New issue 341 by webjamy: Support pdf417 on iphones and Android phones
http://code.google.com/p/zxing/issues/detail?id=341

Hi,

First : thanks for your great job, it's very nice ;)

I have a question about support "decode pdf417" on mobile devices.
I see here :
http://code.google.com/p/zxing/issues/detail?id=323&can=1&q=pdf417
that pdf417 will not support.

Can you tell me why this barcode isn't support on Android phones and
iPhones ?
Now, we have a 5 million pixels on board and 3 for iPhones.
I would like to try on an android phone but before develop it I would like
what do you think
about ?

Thx

JM

It's not a question of pixels, but of both focus and blur. Even with
auto-focus cameras
(which the iPhone doesn't have, except the 3GS), hand-shake blurs the image
and
makes it quite hard to decode PDF417, which was not meant to be scanned
this way.

Ok, thx for your answer.

Nevertheless, if I want decode pdf417 on android, just to try it.
In BarCodeScanner code, I changed the method setDecodeAllMode() in
com.google.zxing.client.android.DecodeThread like this :

private void setDecodeAllMode() {
doSetDecodeMode(BarcodeFormat.UPC_A,
BarcodeFormat.UPC_E,
BarcodeFormat.EAN_13,
BarcodeFormat.EAN_8,
BarcodeFormat.CODE_39,
BarcodeFormat.CODE_128,
BarcodeFormat.ITF,
BarcodeFormat.QR_CODE,
BarcodeFormat.PDF417); //ADD PDF417 support
}

Is it ok ?

You can test it for yourself of course, but we won't accept this change to
be checked in. Besides not working well,
it will slow down scanning significantly.

Oki thank you.

I test it on Motorola Milestone (Android) and it works partialy.
Some PDF417 can't be decode (bad print, ...).

You just need to set the HINTS extra on the request Intent to PDF417.

Could this be disabled by default, but be available as a user selectable
option?

I agree; even if the functionality is poor, increasing quality in cameras
will result in greater accuracy on parsing these images. There are already
enable/disable options for three types, adding one more seems extremely
reasonable.

I ported the C# code to objective-C and integrated it with the latest zxing
codebase and checked it all into github for scanning PDF 417 barcodes. It
definitely works for some barcodes in the ScanTest application. You can
download this at: https://github.com/adamgf/zxing_iphone_pdf_417
