Change History (most recent first):
|
|
|
|
<10> 10/22/91 RB Add support for sfnt-embedded-bitmaps
|
|
<9> 9/25/91 jlf Moved sfnt_PackedSplineFormat from sfnt.c to this file and
|
|
rolled in mr's SOFTRELEASESFNTFRAG modifications.
|
|
<8> 12/11/90 MR Add use-my-metrics support for devMetrics in component glyphs.
|
|
[rb]
|
|
<7> 12/5/90 MR Remove unneeded leftSideBearing and advanceWidth fields. [rb]
|
|
<6> 12/5/90 RB Change reverseContours to unused1, since we don't use it, since
|
|
the scan converter now uses non-zero winding number fill. [mr]
|
|
<5> 11/27/90 MR Need two scalars: one for (possibly rounded) outlines and cvt,
|
|
and one (always fractional) metrics. [rb]
|
|
<4> 11/5/90 MR Add Release macro
|
|
<3> 10/31/90 MR Add fontFlags field to key (copy of header.flag) [rb]
|
|
<2> 10/20/90 MR Change to new scaling routines/parameters, removed scaleFunc
|
|
from key. [rb]
|
|
<12> 7/18/90 MR Change error return type to int
|
|
<11> 7/13/90 MR Declared function pointer prototypes, Debug fields for runtime
|
|
range checking
|
|
<8> 6/21/90 MR Add field for ReleaseSfntFrag
|
|
<7> 6/5/90 MR remove vectorMappingF
|
|
<6> 6/4/90 MR Remove MVT
|
|
<5> 6/1/90 MR Thus endeth the too-brief life of the MVT...
|
|
<4> 5/3/90 RB adding support for new scan converter and decryption.
|
|
<3> 3/20/90 CL Added function pointer for vector mapping
|
|
Removed devRes field
|
|
Added fpem field
|
|
<2> 2/27/90 CL Change: The scaler handles both the old and new format
|
|
simultaneously! It reconfigures itself during runtime ! Changed
|
|
transformed width calculation. Fixed transformed component bug.
|
|
<3.1> 11/14/89 CEL Left Side Bearing should work right for any transformation. The
|
|
phantom points are in, even for components in a composite glyph.
|
|
They should also work for transformations. Device metric are
|
|
passed out in the output data structure. This should also work
|
|
with transformations. Another leftsidebearing along the advance
|
|
width vector is also passed out. whatever the metrics are for
|
|
the component at it's level. Instructions are legal in
|
|
components. Now it is legal to pass in zero as the address of
|
|
memory when a piece of the sfnt is requested by the scaler. If
|
|
this happens the scaler will simply exit with an error code !
|
|
<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
