Does anyone know of a free or 'cheap' barcode generator that will work with CF?

Barbecue.

Nice job!  One shortcut you could add is grabbing the graphics object from the CF image instead of creating a new bufferedImage (slight savings). That is a trick I have used in the past:

ie     ...

        width  = image.getWidth(JavaCast("null", ""));

        height = image.getHeight(JavaCast("null", ""));

        cfImage = imageNew("", width, height);

        graphics = ImageGetBufferedImage(cfImage).getGraphics();

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

See the iText API for Barcode.

An example:

<cfscript>

code128= createobject("java","com.lowagie.text.pdf.Barcode128");

code128.setCodeType(code128.CODE128);

/* Set the code to generate */

code128.setCode("0123456789");

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

image = code128.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>

<!--- Output the code as an image --->

<cfimage action="writeToBrowser" source="#barcodeImage#" format="jpg">

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.
