MathType 5 SDK
Extracting Baseline Info from an EPS File

Last Update: October 12, 1995

Products: MathType (all platforms)

MathType (version 2.0 and later) inserts a comment describing the distance in points from the bottom of the frame rectangle to the baseline of the equation. For example:

This information can be made use of by page layout programs to ensure proper alignment of the equation baseline with that of a text line in which it is pasted.

This information is available as a “Baseline” comment in the header of the EPS files produced by MathType. The following is the header of a typical EPS file:

%!PS-Adobe-2.0 EPSF-1.2
%%BoundingBox: 0 0 7 14
%%Creator: MathType
%%Title: test.eps
%%CreationDate: 2/12/90

%%Dimensions: H=0.194in, W=0.097in

See the Design Science SDK document Setting PICT Baselines (Macintosh) for information on baseline positioning for PICT equations produced by MathType/Equation Editor for the Macintosh. See Setting WMF Baselines (Windows) for baseline positioning in Windows Metafiles (WMF) equations produced by MathType/Equation Editor for Windows.
