I am developing dynamic symbolic execution tool for Java programs. Now I am using it as fully automatic tool for defect detection on some open source programs from GitHub. It has found some java.lang.ArrayIndexOutOfBoundsExceptions in VectAlign:

java.lang.ArrayIndexOutOfBoundsException: -1
	at com.bonnyfone.vectalign.techniques.BaseFillMode.checkPenPosValidity(BaseFillMode.java:110)
	at com.bonnyfone.vectalign.techniques.BaseFillMode.fillInjectedNodes(BaseFillMode.java:101)
	at com.bonnyfone.vectalign.VectAlign.align(VectAlign.java:120)
	at com.bonnyfone.vectalign.Main.main(Main.java:104)
	at jia.test.big.VectalignTest.main(VectalignTest.java:23)

Constructed input was manually minimized to -s L -e M.

Arguments to and from (returned from method doRawAlign) of fillInjectedNodes method are empty ArrayLists. So I think either doRawAlign should not return empty lists or checkPenPosValidity should have additional check on its arguments.

Input is incorrect, so, please let me know is this a bug or undefined behavior caused by incorrect input. In other words, do you think analyzer has reported a real bug or a false positive.

Hey bonny, im new on github and i wanna use this repository but dont know how, is there a tutorial or something I can watch to know exactly how to open and use the jar in command line? thanks

So, when playing with vectalign I noticed that it fails a lot of the time when trying to morph between assets where the "centerline", that is, the visual rotation axis where two assets should meet at an intermediary representation, isn't aligned.
Take a play and a pause icon for example:
The play icon is "visually", with respect to its symmetry, rotated 90 degrees clockwise relative to the pause icon. Rotating the play icon -90 degrees before morphing generates a much smoother transition.
Solution would be to add a rotation to one/other of the assets in the transition.

ALIGNMENT RESULT

new START path:

new END path:

These sequences are morphable and can be used as 'pathData' attributes inside of VectorDrawable files.

why?

so that all could run it without the need to compile it first.

Hi @bonnyfone

Thank you for this library.

I hope you help me with this issue.

Hello!

I tried to download the precompiled .jar but bintray is not hosting it anymore. Can you please set up another source for it?
Cheers,
Best wishes,
