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>

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", ""));

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