Scanning Bitmaps or JPegs for Barcode
-
I would like to know where to start looking to create an application to read barcodes from images. I have very little knowledge of how an image file works. Does anyone have any ideas on where I can start looking?
Not sure if this will help - I did it years ago in 'C'. Back then we read the file as a binary input. found the width and height in the bitmap header file ( you should be able to find the structure layout on the net or use an API function. Having discovered the start bit/byte (depends on the format) you can read across the pixels noting the colours. Black on white should be relatively easy. Other colours need some thought! Good luck. I'm sure I've seen a sample of this in VB5 or VB6. I haven't migrated to .Net yet so couldn't say about that. Alan ...
