### 5.9.1 Understanding how equations are processed

Mif2Go produces graphics for FrameMaker native equations, essentially screen renderings in WMF or bitmap form. The content is not editable as such, but the rendition appears correctly in all output types.

For DITA XML output, equations become <image> elements in a <fig> element; see §15.7.5 Including MathFullForm equations in <alt> elements. For DCL representation, Mif2Go keeps both the native FrameMaker MathFullForm and the graphic rendering. Although all current output types except DITA use only the graphic, the MathFullForm is available also, in DCL.

Mif2Go always uses FrameMaker export filters to write native FrameMaker math equations as graphics, whether or not you direct Mif2Go to use those filters for graphic images in your document.

Despite the unfortunate key name, the following setting does not actually affect the production of equations; provisionally, it affects the production of graphics:

[Setup]

; WriteEquations = No (default) or Yes (write equations as graphics)

When WriteEquations=No, equations (and graphics, provided [Graphics]UseGraphicPreviews=Yes) are converted with FrameMaker export filters.

When WriteEquations=Yes, only equations are converted with FrameMaker export filters. Unless [Graphics]UseGraphicPreviews=Yes, the graphics in your document are processed some other way, or not at all.

The purpose of WriteEquations=Yes is to allow you to experiment with settings for equations without processing the rest of the document. Usually you would not change this setting in the configuration file. Instead you would use the Mif2Go Export dialog; see §5.9.2 Specifying equation size and DPI.
