### prda_GetKernAmount

Determines the amount of kerning space appropriate between the two given characters. This is in Adobe style (1000x1000) units. The value is signed; a negative value indicates that the characters should be pulled closer together and a positive value indicates that they should be pushed further apart.

Warnings:

The code points provided must be in the code page the font is designed for, not the code page the application is using. For fonts with Winthorn multi- code page support, this indicated that the code points must be in extended code page 850 form (presently a value 1-316).
