Hello,
I'm currently working at a customer site to develop an interactive form with a barcode on it. I have certain preferences I need to keep in mind when developing: The barcode should not be larger than 5.868cm(width)x2,665cm(height) (thats 2inx0.74in), the data should be in a semicolon-separated string and contains about 1500 - 1800 characters. After various tests and what I have read in these forums (Barcoded Forms and Designer 7) I'm not quite sure I can size the barcode with these preferences.
In one of the postings here I found a calculation on how to determine the width and height of a barcode based on rows and columns:
width = num columns * 17 * module-length
height = num rows * Y/Y ratio * module-length
Am I right that the multiplication of columns and rows give me the maximum amount of data I can put into the barcode? But what indicates this number then, ASCII-characters or bytes?
Has anyone had any experience with these calculations? Can I rely on these?
Also, I did some test in Designer: I put in a paper form barcode object and a simple textfield. I resized the barcode to match my requirements, and set the max textfield length to 255. And received a red circle at design time indicating that the barcode is too small or the amount of data too large! When I set the length to 97 the red circle disappeared!
From above calculations I got a number of 10 columns and 39 rows, but you can't tell me that this means just 97 ASCII-characters!!!
I'm really very, very confused. Any help in sizing the barcode is greatly appreciated and urgently needed!
Thanks very much in advance!
Regards, Karin
