How to disable PostScript Comments on Macintosh PICT files

The information in this document applies to:

Issue

When saving MathType equation objects as PICT files, PostScript comments are written by MathType. These are commands for drawing the whole equation in PostScript rather than QuickDraw. When saving PICT files, the size of the file is larger then saving it without the PostScript comments. Also, when using PICT files in PowerPoint (98, 2001, X and 2004) the "Recolor" command does not work with the embedded PostScript information. You will receive this error message " PowerPoint cannot recolor this picture. This picture has no colors or fills, or it contains embedded PostScript information".
 

Solution

You can disable the PostScript comments by editing the MathType Preference file on your computer. Follow the steps below:

1. Close MathType
2. Navigate to: Harddrive\Users\~your user name folder~\Library\Preferences\
3. Open the "MathType 5 Preferences" or "MathType 6 Preferences" file with a text editor
4. Change the line EmbedPSInPict=1 value to 0
5. Save changes to the preference file
