I'm lo开发者_如何学Gooking for Delphi headers to use with the zebra lib
I was lucky to find Delphi headers for Zbar at ftp://ftp.lnssoftware.ca/Delphi/zbar.pas which was great, but I would really like to find headers for zebra
Q1: Can anyone point me to a download location?
Q2: I would like to evaluate some barcode scanning solutions, so if anyone can recommend something that works in Delphi that would be great.
My employer has a 2D DataMatrix barcode on every document and form that is sent out. We then scan the results using an OPEX Scanner The resulting TIFF images we send to the SoftTek Barcode Reader which allows us to quickly identify the incoming form and account information. Since it's an ActiveX control we were able to user it in Delphi easily.
We evaluated several options for reading barcodes but found that the SoftTek library allowed us to get the best read rates. It's not a cheap library but it's has proven that it's value to our organization.
I just took a look at Zebra, the Version Control System had all the files deleted out of it on Sept 23, 2010. I can't see where they may have (if they did) move the repository.
Browsing through the 51 revisions you can see the files that were available. But it appears that the project owner either did not know how to use version control or was playing around. Personally I would shy away from this library based on what I have seen in SVN.
The unit you link to looks pretty good, but it does 'late binding', to convert the unit to 'early binding' replace all the functions and procedures in the implementation section to something of this syntax:
function xxx; external 'libzbar-0.dll' name 'xxx';
where xxx is the name of the function (and 'xxx' the parameter to GetAddressOf, but is in most cases the same)
