Interpreting the baseline Products: MathType for Windows MathType stores coordinate information in WMF files in 1/16th of a point, where there are 72 points per inch. The following describes how to convert this value to screen coordinates: Once the baseline value has been obtained, it needs to be converted to points: Then converted to inches: And finally, converted to pixels*: For example, if we obtain a baseline of 64: * In this example the number of pixels per vertical inch is 96, your results may differ, and so you should obtain this value at runtime using the call: ::GetDeviceCaps(HDC, LOGPIXELSY). While this example demonstrates how to convert to pixels, it should help you convert to whatever coordinate system your application uses.
