Change default height from 100 to 1

The default height of 100 causes unwanted results with the "blank" space between EAN13 and EAN5 add-on codes in PDF rendering app wkhtmltopdf (which uses the Webkit browser). This problem goes away when the default is changed to 1.

Did you even succeed with wkhtmltopdf to generate the barcode image? I tried failed with it. My PDF file always display blank for the barcode image which generated by jsbarcode.

Apart from the issue with add-on barcodes I've had no problems rendering in wkhtmltopdf. Maybe try and add the --debug-javascript flag to the wkhtmltopdf command to see what could be the problem, or delay the javascript with --javascript-delay.

I did tried -javascript-delay command, it's not working even I waited 10 seconds. Because I'm using another framework called openhtmltopdf to convert it, I'm not able to get the debug info by -debug-javascript, Could you help me check what is the problem if you have free time? It would be very helpful.

Don't bother. I download the binary of openhtmltopdf, and debug the js, also find the problem.
