Help placing more than 85 words

[mike]

I have wordCram running as an applet and seems to work well unless I try to place more than 85 words.

Here's the main I'm using for wordcram:

And here is the html test page I'm using for the applet:

I'm getting an NPE in Animation Thread at BBTreeBuilder.makeTree  - line 32.

Here's the full stack trace:

Exception in thread "Animation Thread" java.lang.NullPointerException

at wordcram.BBTreeBuilder.makeTree(BBTreeBuilder.java:32)

This is very curious to me, since the way I'm using wordCram works without fail for 85 or fewer words, but gets this NPE at 86 words or above. Any help would be greatly appreciated. Thanks a lot in advance!

That's odd. Which version of WordCram are you using?

I found the problem, running with 0.5.7: you're setting minShapeSize to zero. If you set it higher, even to 1, it should work.

Setting it to zero means that you want to render any word shapes, even if they're less than 1 pixel wide or high, and it looks like the bounding box trees can't handle such small shapes.

I'll put in a bug fix for the 0.6.0 release to limit minShapeSize to 1 or greater.

(Actually, to be precise, the cause was that you were setting minShapeSize to zero, and using Sizers.byWeight(0, 30). If you set the lower bound on the Sizer to be 1, it'll fix the problem, too.)
