1. Typography.OpenFont

• This project is a core project, no dependency on others.
• This project contains a font reader that implements Open Font Format,
  (ISO/IEC 14496-22:2015 , and Microsoft OpenType Specification)
  and Web Open Font Format (both WOFF 1.0, 2.0)
• OpenType GSUB, GPOS layout mechanism are 'sleep' in here.
• No Visual/Graphics Rendering Here

2. Typography.GlyphLayout

since GlyphLayout engine is not stable and quite complex,
I separated this from the OpenFont core project

• This project invokes OpenType Layout Engine/Mechanism (esp. GSUB, GPOS) inside the
  Typography.OpenFont
• The engine converts a string to a glyph-index List and substitutes some glyph,
  and place them into a proper position by the request 'settings'
  eg see Add ScriptLang ComboBox #82,
  or Emoji Font :) #18
• No Visual/Graphics Rendering Here

With Typography.OpenFont + Typography.GlyphLayout

you can use the font data/ text/ glyph position to
render to 'your' render surface.

I provide the example for this

eg ...

• Render to classic GDI+ WinForms => https://github.com/LayoutFarm/Typography/tree/master/Demo/Windows/GdiPlusSample.WinForms

• Render to PixelFarm => https://github.com/LayoutFarm/Typography/tree/master/Demo/Windows/PixelFarmSample.WinForms

or other projects that use only 2 libs and render the data to their surfaces.

see ...

• https://github.com/samhocevar/emoji.wpf

• https://github.com/zwcloud/ImGui

• https://github.com/MatterHackers/agg-sharp

What about Typography.Contours and others?
Typography.Contours targets .NET Framework 2.0 and cannot be referenced from .NET Standard 2.0.

But when I want to parse a long text and render like this ...

The HtmlRenderer example!

This is a snapshot of Html drawboard from (https://github.com/LayoutFarm/HtmlRenderer).
The glyphs are generated/layouted with our Typography, and rendered with
the PixelFarm (https://github.com/PaintLab/PixelFarm)

pic 1: HtmlRenderer on GLES2 surface, text are renderered with the Typography

I need more functions about how to parse a long text
and layout it.

So I need more functions, Those are in development stages.

3. Typography.TextServices

   This is a hub of doing some advance things about how to parse a long text and layout them
   The project contains 2 sub-projects( TextBreak and TextFlow)

4. Typography.TextBreak

• This implements text-break engine.

• Implements how to break a long text to a list of 'textspan'
  for some languages(eg English) , a text can be parsed into a list of textspan by whitespace break
  but some languages (eg Thai, Laos) can't, They need more advance parsing algorhytm eg=> Dictionary Breaking Engine.

5. Typography.TextFlow

• This implements text flow. How to flow a text into a specific shape area.

This should probably be put in README.

6. FontAtlas see

You can see in the pic1 that I render the Html into OpenGLES2 surface.

Rendering a text on GLES2 surface may has multiple ways

One technique is using Font texture atlas.

I provide How to create font Atlas in the project

7. Msdf Texture see

   When we talk about FontAtlas.
   There are many kind of Font Atlas.

   If you need scalable texture font with 'Sharp' edge=>
   one of them is Multi-channel signed distance field (Msdf) Texture

   I also 'port' Multi-channel signed distance field (Msdf) Texture
   (https://github.com/Chlumsky/msdfgen) from C/C++ to C#

8. Typography.Contours

• This is a developing project.
• I use this for glyph shape analysis/study.
• I try to implement AutoHint here

eg.

pic 1: grid w,h (1px,10px)

pic 2: grid w,h (1px,10px)

(see PaintLab/PixelFarm#4 , #37)

Under development Typography.Contours

Century font, A, 460pts

pic 1: master outline

pic 2: from 1

pic 3: from 1, master outline with edge offset -10px (thin)

pic 4: from 3

pic 5: from 1, master outline with edge offset +10px (thick)

pic 5: from 4

Naming something sometimes quite hard :)

Welcome all new suggestions about that.

Can you post this useful information at README?
