2. The Illustrator files The Illustrator files in your Mountain High Maps collection are saved in Illustrator eps format, and are readable by all versions since then as well as all applications which can read eps format files. Illustrator files are “vector” files, meaning they can be used at any size, without requiring any change of resolution – unlike the relief maps and masks, which are bitmapped, and which may require additional treatment in an image manipulation application if they are to be used at wildly differing sizes from the originals. The Illustrator files are identified in the Mountain High Maps collection by the suffix “.eps” as in “1.01 Africa.eps.” End of Chapter To view the Table of Contents click in the bar below (in the lower right of this window), or select another chapter from “Contents” in the Menu bar.
