Link to .capx file (required!):

https://dl.dropbox.com/u/6200498/Construct%202/capx/bugged/9patch_powerof2-bug.capx

Steps to reproduce:

1. Place a 9-Patch object width dimensions != power of 2.

2. Preview with web gl on AND off.

Observed result:

Exception with web gl OFF:

Javascript error!Uncaught Error: InvalidStateError: DOM Exception 11http://localhost/NinePatch_plugin.js, line 149 (col undefined)

Exception with web gl ON:

Javascript error!Uncaught Error: InvalidStateError: DOM Exception 11http://localhost/glwrap.js, line 1292 (col undefined)

I guess this is the stretching routine for non power of 2 textures.

Expected result:

No exception thrown / 9-patch working stretching routine. ;)

Browsers affected:

Chrome: yes

Firefox: yes

Internet Explorer: very possible

Operating system & service pack:

Windows 7 Prof.

The problem isn't to do with power-of-two sized textures, it's just the margins you've set mean the edge has a zero size. (The image is 32px high, and the top and bottom margins are 16px, meaning the left/right edges have a zero size.) If you reduce the margins it works fine. Still, it shouldn't have an error like this, so I'll get this fixed for the next build.
