Encapsulated PostScript (EPS)
EPS files can contain text, vector graphics, and bitmaps and are intended to be included (encapsulated) in other documents. Unlike other PostScript files, which can contain multiple pages, an EPS file is always a single page.
EPS files usually contain a preview image (header) that lets you view the file content without the help of a PostScript interpreter. An EPS file without a preview image is displayed as a gray box in Corel applications.
You can import and export EPS files. You can import an EPS file as a group of editable objects as you would import any other PostScript (PS) file. You can also bring the file as encapsulated, placing the preview image in the drawing window. The preview image is linked to the file. It is recommended that you import an EPS file as encapsulated in the following situations:
|
•
|
|
You want text in the EPS file to be displayed with the original fonts, without any font substitutions.
|
|
•
|
|
You are working with a large EPS file, and you don’t want to slow down the application.
|
To import an encapsulated PostScript file
|  |
|
1.
|
|
Click File  Import. |
|
2.
|
|
Locate the folder in which the file is stored.
|
|
3.
|
|
Do one of the following:
|
| |
•
| |
(Windows Vista) Choose PS, EPS, PRN – PostScript (*.ps; *.eps; *.prn) from the list box next to the File name box.
|
| |
•
| |
(Windows XP) Choose PS, EPS, PRN – PostScript from the Files of type list box.
|
|
6.
|
|
In the Import EPS dialog box, enable one of the following options:
|
| |
•
| |
Import as editable —brings in the file as a group of CorelDRAW objects that you can modify
|
| |
•
| |
Place as encapsulated PostScript —places the preview image in the drawing. You cannot modify specific parts of the file, but you can edit the file as a whole by applying transformations, such as sizing and rotation.
|
|
7.
|
|
If you are importing the file as editable, enable one of the following text options:
|
| |
•
| |
Text — preserves text objects in the imported file so that you can edit the text
|
| |
•
| |
Curves — converts text to curves
|
|
•
|
|
If the EPS file contains text converted to curves, the text in the imported file is not editable, even if you choose to import the text as text.
|
|
•
|
|
You can also drag an EPS file from Windows Explorer into the drawing window.

Encapsulated PostScript (EPS) technical notes
| |
Importing an EPS file
|
•
|
|
When you import an EPS file as editable, the PostScript information in the file is converted to native CorelDRAW objects that you can edit with some restrictions. For information about these restrictions, see “PostScript (PS or PRN) technical notes.” |
|
•
|
|
If the encapsulated PostScript file was imported with the Place as Encapsulated PostScript option, and if it contains a preview image (called a header), the preview image is imported and displayed. The EPS information remains attached to the header and is used when the image is printed to a PostScript printer.
|
Exporting an EPS file
|
•
|
|
On a PostScript printer, graphics exported to the encapsulated PostScript (EPS) format print from other programs exactly as they do from a Corel graphics programs.
|
|
•
|
|
You can save a header to the Tagged Image file format (TIFF) or Windows Metafile format (WMF) in black and white, 4-bit grayscale or color, or 8-bit grayscale or color. You can set the header resolution between 1 and 300 dots per inch ( dpi); the default header resolution is 72 dpi. If the program importing the EPS file has a limitation on the image header size, you might receive an error message stating that the file is too large. To reduce file size, in the EPS export dialog box, choose Black and White from the Type box, and lower the header resolution before exporting the file. The setting determines only the resolution of the header and has no impact on the print quality of a drawing. Color headers are useful for viewing EPS files. If the program in which you are going to use the file does not support color headers, try exporting with a mono header instead. You can also export without a header. |
|
•
|
|
Along with the graphic, exported EPS files contain a filename, program name, and date.
|
|
•
|
|
To save font information in an EPS file, enable the Include fonts check box in the Export text as area.
|
|
•
|
|
If you export text as curves, text is converted to vector curves.
|
|
•
|
|
If a font used in the file is not available on the printer or has not been saved in the file, either the text is printed in Courier font or the drawing is not printed.
