Change History (most recent first):
|
|
|
|
<4> 9/25/91 jlf Corrected definition of ReleaseSFNTFunc by adding a long parameter
|
|
before the void* param. Defined RELEASE_MEM_FRAG conditional.
|
|
<3> 11/27/90 MR Add #define for PASCAL. [ph]
|
|
<2> 11/5/90 MR Move USHORTMUL from FontMath.h, add Debug definition [rb]
|
|
<7> 7/18/90 MR Add byte swapping macros for INTEL, moved rounding macros from
|
|
fnt.h to here
|
|
<6> 7/14/90 MR changed defines to typedefs for int[8,16,32] and others
|
|
<5> 7/13/90 MR Declared ReleaseSFNTFunc and GetSFNTFunc
|
|
<4> 5/3/90 RB cant remember any changes
|
|
<3> 3/20/90 CL type changes for Microsoft
|
|
<2> 2/27/90 CL getting bbs headers
|
|
<3.0> 8/28/89 sjk Cleanup and one transformation bugfix
|
|
<2.2> 8/14/89 sjk 1 point contours now OK
|
|
<2.1> 8/8/89 sjk Improved encryption handling
|
|
<2.0> 8/2/89 sjk Just fixed EASE comment
|
|
<1.5> 8/1/89 sjk Added composites and encryption. Plus some enhancementsÉ
|
|
<1.4> 6/13/89 SJK Comment
|
|
<1.3> 6/2/89 CEL 16.16 scaling of metrics, minimum recommended ppem, point size 0
|
|
bug, correct transformed integralized ppem behavior, pretty much
|
|
so
|
|
<1.2> 5/26/89 CEL EASE messed up on ÒcÓ comments
|
|
<¥1.1> 5/26/89 CEL Integrated the new Font Scaler 1.0 into Spline Fonts
|
|
<1.0> 5/25/89 CEL Integrated 1.0 Font scaler into Bass code for the first timeÉ
