There are multiple ways to generate Code 128 barcodes. Barcode4j and Barbecue are two wonderful java projects that we can use with ColdFusion; both of them generate barcode that can be saved as image files. Code 128 barcode also can be draw using a Code 128 barcode font. They are not that dificult to find, even free Code 128 barcode fonts. I guess different situations favor font over images or vise versa. But I been working on an InDesign server project, I choose to go with Code 128 font. (more..)

I was working on QR barcode using Zxing and the barcode generated by Zxing tend to give extra white spaces on some barcodes but my designer wanted trimmed image without extra white space around. ColdFusion does not have an image trim function, so I put together a small function to trim background of an image. This function takes two arguments. Image (required) This can take ColdFusion image object or path to an image file. (more..)

Too often I write “It was too easy with ColdFusion”, it’s becoming a cliché now. Making a QR barcode with ColdFusion was extremely easy too, specially when someone else have already blog about it. I had nothing to dig out, nothing to investigate or haven’t had the need for countless cups of coffee. I wish everything works like that.This uses Google zxing java library. I put necessary classes into a single jar file and you can download the example below. (more..)

I know PostNet is about to expire in couple of months. But today I had to create few shipping labels, and put to gather a simple function to assemble PostNet String. Mind you, this does not create the actual PostNet barcode. I use a PostNet Font to create the barcode, this is to create a valid PostNet string from a ZIP Code so you can print it with a PostNet barcode font. Pass your zip5 or zip9 to the function, it will return the string to be printed. (more..)

Most of the barcode readers don’t support Unicode. Barcode readers connected to USB or the keyboard port only able to supply characters available on the keyboard since they act much like keyboards. Most of Unicode characters required additional processing through uniscribe before there were rendered on the screen and even Windows XP doesn't contain complete uniscribe for most of languages and simple barcode readers defiantly could not process Unicode directly.

Last few days I had quite nice time trying to create barcodes. This post here, explains how to create a datamatrix barcode with java4less and it helps me to present the project before the deadline. So Thank You Stillnet Studios. Now here is another way to create Datamatrix 2D barcodes with barcode4j, an open source project.You need :1. Barcode4j (download here)2. Administrative access to Coldfusion MX or JavaLoader CFC (download here)3. (more..)

Here I created a CFC wrapper from the previous code for creating a datamarix barcode with barcode4j. You can output EPS, PNG and JPG files, but EPS is the best format if you are planning to use it inside PDF, it can reduce printing time if you are using a digital printer. Even though you can create JPG output, it can seriously affect the reading part. In other words, using JPG is not an very good idea. (more..)
