Barcode to Image

[danp]

Hi,

I'd like some help if possible with rendering a barcode to an image.  

I want to align a barcode and have found that its not possible using the barcode element however you can do this by rendering it to an image.

I'm currently using

new net.sf.jasperreports.components.barbecue.BarbecueRenderer(net.sourceforge.barbecue.BarcodeFactory.createCode128($F{X}))

where $F{X} = '123456789'

SQL Used:

select

'123456789' x

from dual

 

Which produces:

 

However I'd like to know how its possible to do the same using barcode4j rather than barbecue, and also how to actually remove the text below the barcode.

Any help would be appreciated.

 

Dan

yes, barcode4j supports code128, too.

the barcode4j must have an option like "textPosition", set it to "none".

unfortunately no property to align the bar code. either set a constant width (if possible) or use a minimum width and let the barcode shrink, if the code expression gets longer

Hi Thomas,

 

I'm trying to render the barcode as an image, in the image expression rather than using an actual barcode element from the palette.

 

I'm having trouble with what I actually use for the image expression.

 

I assume it will be something along the lines of:

 

new net.sf.jasperreports.components.barcode4j.........

 

However I'm just not sure what the full expression should be.
