[mpeg-OTspec] Suggested 'MATH' tables corrections [1 Attachment]

[Sergey Malkin]

 Hello Keith,

 

You are absolutely right, those are real errors in the spec. Looks like they
were introduced in the process of converting from our initial Word specs. I
verified data structures against original document as well as actual code
reading MATH table. To make it easier for Vlad to make corrections in the spec,
I'll repeat all correction here:

 

1. In MathConstants table: Fields DelimitedSubFormulaMinHeight and
DisplayOperatorMinHeight should be USHORT instead of signed SHORT

2. In MathConstants table, StretchStackGapBelowMin field of type
MathValueRecord should be added after StretchStackGapAboveMin with following
description: "Minimum gap between the ink of the stretched
element, and the (ink) top of the element below. Suggested:
LowerLimitGapMin."

3. MathItalicsCorrectionInfo table: field
ItalicsCorrectionCount should be of USHORT type instead of SHORT

4. MathTopAccentAttachmentTable: field
TopAccentAttachmentCount should be USHORT

5. MathKernInfo table; MathKernCount should be USHORT

6. MathKern table: HeightCount should be USHORT

7. MathGlyphVariantRecord table: VariandGlyph
should have type GlyphID

8. GlyphPartRecord table: Glyph field should have type
GlyphID

 

Thanks,

Sergey

      Hello,
I have peeked interest in any specification concerning fonts. Especially new tables such as 'MATH'. This group has superior leadership and participation. My only regret is learning about this group after the fact. The fact of ISO draft approval. Perhaps my suggested corrections will beincluded in the "ballot comments". You, the reader, do give Valdimir the feed back he needs...
Regards,Keith
