Re: barcode scanning

It is supposed to be Code 39? They generated it with Word using a Code 39 font. Are you 100% sure before I go back to them?

THanks

Scan in landscape mode....?

Of course I can just rotate the document after scanning, but I am curious if there is a landscape/portrait option when scanning. I didn't find one in a quick search of the docs, but I may have missed it.

Thanks

Re: Xerox 152, Win 7 (64 bit) and possible Vista Issue

Hi Loic,

I updated my hardware specific TWAIN driver (I thought I was running the latest), and it fixed the problem on my Win 7 (64 bit). I'm waiting for a report back on Vista (32 bit).

I'll let you know when I know.

Happy Holidays!

Re: Xerox 152, Win 7 (64 bit) and possible Vista Issue

Additional pieces of information: * I just updated my GDPicture.NET to 6.5.0.2 (the latest I believe), and the problem persists * The same crash happens in your twain scanning sample if I uncheck HIDE UI. I have no idea if this is related, but it happens. If the HIDE UI is checked, it scans. * I've ...

Xerox 152, Win 7 (64 bit) and possible Vista Issue

My application has scanned fine with a Xerox 152 on XP. I recently tried it on Win 7 + 64 bit and it crashed during a scan. The app is targeted for x86. I am also having reports of it crashing on 32 bit Vista using the same Xerox 152 scanner. I am using the latest TWAIN drivers for the scanner. Here...

canceling an ADF scan

If I scan a bunch of documents with ADF enabled and hit the driver's CANCEL button in the middle (on the driver's progress dialog), all the documents continue to be fed into the scanner. Is this a limitation with the driver, or is there something I need to do to capture the cancel button? My code......

Re: Crash when scanning in grayscale

Interestingly, setting the bits/pixel to 8 with grayscale fixed the problem... so perhaps the driver was not able to handle that setting.

Re: Crash when scanning in grayscale

Thanks Loic, I'll get you the info you need on the crash.

But just to confirm... nothing was obviously wrong with my configuration setup?

What do you recommend for the bit/pixel depth if I want to offer the user three simple choices: BW, Grayscale, and Color?

Thanks

Crash when scanning in grayscale

I've had no problem scanning in grayscale with two different scanners personally, but a customer had my application crash during a grayscale scan. Black and white hasn't been a problem for him. Here is the code I use to configure the scanner. I am offering three scan types for the customer to choose...

ADR - why multiple images in a template?

Question -

What is the reasoning behind assigning multiple images to an ADR template? For example: Is that to provide multiple "samples" of a particular document to increase the confidence matching?

Thanks

ADR w/ multipage TIFFs?

How well - if at all - does ADR work with multipage TIFFS? Do I need to compare the pages individually or will the ADR engine compare pages to pages? Any code examples would be appreciated? Also - any hints for getting ADR to work with your typical black text on a white page business forms? I'm havi...
