Printing and Exporting<br />

246<br />

Choose Export as EPS… from the File menu to perform the export process. A window<br />

that lets you choose a destination folder and a file name of the EPS file<br />

appears. Click OK. The EPS options window opens.<br />

In this window, use the arrows to choose the page you want to export (it is only<br />

possible to export one page at a time, due to limitations in the EPS format).<br />

Click the Export button to execute the export or the Cancel button to cancel the<br />

operation.<br />

A Word About Reading EPS Files<br />

If you try to open an EPS file generated from <strong>Igor</strong> <strong>Engraver</strong> in Adobe Illustrator or PhotoShop,<br />

you will get a message saying that the EPS parser encountered an error. This is<br />

because the PostScript interpreter used by those programs only understands a small subset of<br />

the PostScript language, and <strong>Igor</strong> <strong>Engraver</strong> uses several PostScript commands that lies outside<br />

that subset. (An EPS file is basically a program, written in the PostScript programming<br />

language, which when executed results in an image.) If you use Adobe Illustrator,<br />

PageMaker or InDesign, you can instead use the Place command in the File menu. This<br />

will let you "import" <strong>Igor</strong> <strong>Engraver</strong>-generated EPS files into those programs, and print the<br />

files on PostScript printers.<br />

<strong>Igor</strong> <strong>Engraver</strong> generates a bitmapped "preview picture" during the EPS export, and puts<br />

this preview into the EPS file. When you place the EPS into another application, that preview<br />

bitmap is used when the EPS is displayed on the screen. The preview bitmap is generated<br />

by <strong>Igor</strong> <strong>Engraver</strong> at screen resolution (72 dpi), so the EPS may appear to be of poor<br />

quality when viewed on-screen – especially if it scaled or rotated – but it will look fine<br />

when printed on PostScript printers. (If you try to print it on a non-PostScript printer, it<br />

will in most cases look horrible.) If you have Adobe Acrobat Distiller (that is, the full ver-
