12 Mpx is fairly large but I'm guessing the conversion from vector to raster is what's making it go somewhat wonky.
What are you outputting as in Ideas? JPEG?
yes, JPEG. At 40% of the original size, the drawing from Ideas roughly fits the ipad screen, but i already see pixels...
I might have another setting somewhere which mixed up the transfer?
Any chance you have a desktop image editor (or viewer) handy?
A rasterized image is always going to be pixelated...because it's made up of pixels.
Vector images will always appear smooth no matter the magnification due to the mathematical way they're rendered. This is why vector images are best suited for logos (smooth edges, etc.) while raster images are best suited for photographs (due to the complex amount of color gradation).
