When viewing an ArcMap created EPS file, it will be cut off at 54 inches in either height or width. Parts of the image beyond the 54 inch limit are not displayed.
ArcMap incorrectly truncates the Bounding Box of the EPS file when it exceeds 54 inches in height or width.
This can be corrected by manually editing the Bounding Box entry in the EPS file as follows:
Open the EPS file in a dedicated text editor such as Notepad or TextPad to perform this task, rather than a word processor such as Microsoft Word.
Locate the string "%%Bounding Box: ", followed by four numerical values. This should be the eighth line in the EPS file, and contains the Bounding Box's xmin, ymin, xmax, and ymax values.
Multiply the page width in inches by 72. This converts the values into PostScript point units (72 points per inch). For example, a page width of 60 inches would be 4320 points (60 x 72 = 4320). If there are decimal values, round up to the next integer value, to create a new xmax value.
Take the new xmax value calculated in step 3 above and add the xmin value from the EPS file to it. This is the new adjusted xmax value.
Repeat steps 3 and 4 with your page height. This will create a new adjusted ymax value.
Use the new adjusted xmax and ymax values calculated in steps 4 and 5 above to replace the last two numerical values in the "%%Bounding Box: " string in the EPS file.
Save the file (always work on a copy of the original data). View the corrected file.
