Hello one and all,

ColdFusion can go even one better. You can use the iText library, which currently ships with ColdFusion, to generate barcodes!

Here is a proof of concept:

codeEAN = createobject("java","com.lowagie.text.pdf.BarcodeEAN");

codeEAN.setCodeType(codeEAN.EAN13);

codeEAN.setCode("4902555131719");

color = createobject("java","java.awt.Color");

image = codeEAN.createAwtImage(color.black, color.white);

bufferedImage = createObject("java", "java.awt.image.BufferedImage");

bufferedImageType = bufferedImage.TYPE_BYTE_GRAY;

bufferedImage = bufferedImage.init(image.getWidth(JavaCast("null", "")),image.getHeight(JavaCast("null", "")), bufferedImageType);

graphics2D = bufferedImage.createGraphics();

graphics2D.drawImage(image,0,0,JavaCast("null", ""));

barcodeImage = imageNew(bufferedImage);

</cfscript>

Hi BKBK,

Since I found your post I'm looking for documentation on the iText Coldfusion's library sintax. I'll try to generate Code128C barcodes but not found the exact sintax based on your code.

Thanks in advance.

I had a look at the API and I can't see how to set the barcode width. I can set its height with "code128.setBarHeight(x);" but none of the parameters I tried (setX, setN...) seems to affect the overall size of the barcode and, as it gets rendered, it's unusable because the bars are too close to be read once printed.

I don't know where to look further.

If I use Coldfusion's ability to resize the resulting image, the result is too fuzzy because the bars become blured and the barcode reader can't read them properly.

I'm stuck!

Any suggestion will be much appreciated.

Thanks in advance.

Looks like that is all about making charts? Where is something about
generating barcodes?
