Great software and nice to see an update. Kudos for using Atkinson dither.

I've not used the software since upgrading my OS and Java. Now I get this error with the online version: Cannot find cached resource for URL:

Offline version says:

Any ideas what I'm doing wrong? (Latest Java 7, 64 bit Mac OS X)

Well I did improve upon Atkinson ("Low Error Atkinson") especially for this program :) As for you problem - it seems that your browser is still using the default Apple version of Java 6 rather than Oracle's Java 7. The major.minor version error is caused by the fact that it was compiled for a later Java version. The cached error you also see is a consequence of not being able to load this code.

Hi Benjamin,

Thanks for the reply. I've always used Hypercard for pixel art because of that reason :) HyperDither is a good OS X app to get around that, although I've never found a retro paint program better than the toolset in Hypercard... I was hoping to compare the 'contrast enhanced' filter in HyperDither to your implementation, but alas.

Java on the command line gives me this:
java -version
java version "1.6.0_51"
Java(TM) SE Runtime Environment (build 1.6.0_51-b11-456-11M4508)
Java HotSpot(TM) 64-Bit Server VM (build 20.51-b01-456, mixed mode)

Java's control panel and browser plugin lists 1.7 (1.7.0_25)

and an Oracle launcher pops up when attempting the launch the web version. Safari is pretty strict about having the newest version installed. I don't know how to get around this!

I don't know what to suggest as I don't own a Mac, perhaps the Oracle Java install page mentions something? You could always try the standalone version and see if that works or could use the command line if you get desperate "java -jar /path/to/jar/imagetozxspec.jar" if memory serves me.

One suggestion, if you ever make a follow-up - either move the "convert" button to the top of the screen, or make it so that the window scales to 90% of the screen's vertical resolution.

I find that if I process a large image the "convert" button ends up hidden underneath the taskbar. Apart from that it's ace!
