Screen capture didn't work well. I'm looking for the artwork from the picture shown in medium to high resolution...can't seem to find it on the net. What's my next step? Contact Atari?
"Resolution" implies a raster image. For this much of a resize, you
really need a vector image.
If you aren't familiar with the difference between raster and vector images and/or how to convert a raster image to a vector image, download Frostillicuss' tutorial
here and read through the artwork FAQ
here.
According to the MAME info box, the native resolution for Super Sprint is 512 x 384 pixels. (raster image)
That resolution is
obviously too low to print a decent sized cab-art image.
If you leave it as a raster image when you resize, you will get "jaggies".
For the best results, start with a native res screen capture raster image like
this one.
- Use a lossless format like .PNG,
not a lossy format like .JPG.
- You might want to trim the small text at the bottom before converting to vector format.
-- Cropping/repositioning is OK, but don't stretch/compress the part of the image you want to vectorize.
- Convert that raster image to a vector image.
-- Most vector image programs can do the conversion automatically.
- Verify that the vector lines look good and do any needed cleanup/adjustments.
-- There are a lot of tilted straight lines in the image so you may need to turn some "stair steps" into a "smooth ramp" by deleting some of the mid-points.
- Resize the vector image to the desired dimensions.
-- You won't get any "jaggies" that aren't part of the vector image.
