The little white line on animation problem: What are ideal Resolution, Mode, and bit depth to set when exporting adobe illustrator vector files to animation frames for iTorque?

I've created my desired graphics in vector format. (adobe illustrator) What I've been doing is utilizing an adobe photoshop script to take my individual animation frame vector images and convert it to a spritesheet for iTorque. (for anyone interested, this nifty script called sprite sheet explorer is here: http://asouza.com/blog/?p=119

I'm getting little white lines on the edges of my animation though.

I suspect, (but I'm not sure, any information would be appreciated) Resolution, Mode, and Bit Depth might be to blame. These are the settings in the Photoshop dialog box when I load an adobe illustrator file in photoshop and convert it to a pixel image.

What are the optimal Resolution, Mode, and Bit Depth to export my animation frames too (assuming the end result will be about a 1 inch tall graphic on the Iphone)


Thanks for any help! :)
