A problem I am having
HI,
Thank you for your greate work batik;
I'm a java developer and I'm using batik to convert svg code to png file.
I'm now meeting with a problem. I think it's a bug of batik;
below is the code in SVGLinearGradientElementBridge.java:127
if (bbox != null && bbox.getWidth() == 0 || bbox.getHeight() == 0) {
return null;
}
if bbox ==null ,then "bbox.getHeight() == 0" will be executed. And the NullPointerException will occor.
please see the svg code in the attachment and the exception below. That file works well in Chrome;
Sorry I can't make a unit test for you.
batik version: 1.7
exception:
Exception in thread "main" java.lang.NullPointerException

Hi,
please, can you file in a bug entry in Jira at [1], attaching short
test case that will allow dev team to reproduce the issue.
