Re: [Quexf-discuss] misaligned band when importing filled in forms

[Paul de G. <pa...@pe...>]

Hi Adam,

Thanks for the help. I did have an issue with page setup however on 
solving that it appears that I'm still stuck on what appears to be a 
basic import. It can't detect the pages.

I've put all the detail below.

Also I've noticed vastly different results by tweaking the sharpness, 
density etc settings of my scanner. Are there any recommendations on 
what works best?

I've put the files I talk about below on rapidshare:
http://rapidshare.com/files/301724724/quexfbug.zip.html

When importing OriginalScanned.pdf (same file I used for page setup) I 
get the following output:

    temp barcode filename: C:\XAMPP\xampp\htdocs\temp\bar39.tmp
    BARCODE: 00000101
    temp barcode filename: C:\XAMPP\xampp\htdocs\temp\bar3A.tmp
    BARCODE: 00000102
    temp barcode filename: C:\XAMPP\xampp\htdocs\temp\bar3B.tmp
    *INVALID - IGNORING BLANK PAGE
    *temp barcode filename: C:\XAMPP\xampp\htdocs\temp\bar3C.tmp
    BARCODE: 00000104


I added the temp barcode filename line - it saves out the cropped image 
used to detect the barcode - you can see the images in the zip file from 
rapidshare.
You can see the image bar3b.tmp.png - it looks like it should be able to 
detect a barcode there however the code says INVALID - IGNORING BLANK PAGE.

Even if I proceed and then upload the OrionSmallScanned.pdf when I 
"verify form" there is a major downward offset of the place where it's 
looking for the marks. Also on other forms even if they were aligned 
perfectly there was still no detection of marks. See 
capture_offsetdownwards.jpg for example.

I'm sure these are very simple problems with someone who knows what's up 
here but I'm completely stumped.

If someone could assist that would be fantastic.

These are the page settings in config.inc.php:
define('PAGE_WIDTH',2480);
define('PAGE_HEIGHT',3507);
define('TL_VERT_TLX',148);
define('TL_VERT_TLY',124);
define('TL_VERT_BRX',380);
define('TL_VERT_BRY',556);
