Font analysis - stethos

This ELP option is available through the Configuration Tab - Rule Assistant - Analyse functions -> Checkbox "Font Analysis":

Important: in section GLOBAL the key PreParsing=ON must be set! Otherwise the Font Analysis won´t work.

Key in configuration file:

FontAnalysis=1

This function creates a text file for each print job in the folder #ELP_FORMS_PATH#debug\#PRINTERNAME# with the file name FontAnalysis_#DATESERIALLONG#.txt. It contains all extractable information of used and downloaded soft fonts:

<FONT_NAME>,<FONT_TYPE>,<FONT_WEIGHT>,<FONT_STYLE>,<ASSIGNED_FONT_NAME>,<USED_GLYPHTABLE>

<FONT_NAME>

the extracted name of the font

<FONT_TYPE>*

0: PCL Bitmapped Font
10: Intellifont Bound Scalable Font
11: Intellifont Unbound Scalable Font
15: TrueType Scalable Font (Outline Font)
20: Resolution-specific Bitmapped Font

<FONT_WEIGHT>

-7: Ultra Thin
-6: Extra Thin
-5: Thin
-4: Extra Light
-3: Light
-2: Demi Light
-1: Semi Light
0: Medium, Book, or Text
1: Semi Bold
2: Demi Bold
3: Bold
4: Extra Bold
5: Black
6: Extra Black
7: Ultra Black

<FONT_STYLE>

This entry consists of a decimal number which indicates the structure, the appearance width and the posture of the font.
To decode the information you need to convert the number into binary format like this:
- 992 will result in 1111100000
If your binary is longer than 10 digits then only investigate the last 10 digits. All additional leading bits are reserved.
Split the information into 3 groups: group 1: 5 digits, group 2: 3 digits, group 3: 2 digits
- 11111 000 00
Then have a look at the decimal value of each group:
- Group 1 defines the structure
  - 0 = Solid
  - 1 = Outline
  - 2 = Inline
  - 3 = Contour, Distressed (edge effects)
  - 4 = Solid with Shadow
  - 5 = Outline with Shadow
  - 6 = Inline with Shadow
  - 7 = Contour with Shadow
  - 8 - 11 = Patterned (complex patterns, subject to type family)
  - 12 - 15 = Patterned with Shadow
  - 16 = Inverse
  - 17 = Inverse in Open Border
  - 18 - 30 = Reserved
  - 31 = Unknown Structure
- Group 2 defines the Appearance Width
  - 0 = Normal
  - 1 = Condensed
  - 2 = Compressed or Extra Condensed
  - 3 = Extra Compressed
  - 4 = Ultra Compressed
  - 5 = Reserved
  - 6 = Extended or Expanded
  - 7 = Extra Extended or Extra Expanded
- Group 3 defines the Posture
  - 0 = Upright
  - 1 = Italic
  - 2 = Alternate Italic
  - 3 = Reserved

<ASSIGNED_FONT_NAME>

This name was assigned to the font for better readibility.

<USED_GLYPHTABLE>

none: no glyph table used because font type is not supported
default: default glyph table
<GLYPHTABLE_NAME>: integrated glyph table from convert.exe
<GLYPHTYBLE_NAME.gly>: external glyph table

Further information regarding glyph tables can be found here.

Examples:

Internal glyph table: E640702C05D1C822F0121F2CC8A7EA74CB64EE02FEC03F4A461AEA30F35EBB9A
External glyph table file: E640702C05D1C822F0121F2CC8A7EA74CB64EE02FEC03F4A461AEA30F35EBB9A.gly

*) Each <FONT_TYPE> may contain multiple different Character Format Definitions:

<CHARACTER_FORMAT_DEFINITIONS>

0 = PCL Bitmap
4 = LaserJet Family (Raster)
10 = Intellifont Bound Scalable
11 = Intellifont Unbound Scalable
15 = TrueType Scalable (bound or unbound)
20 = Resolution-specific Bitmap

Note: These Character Format Definitions can only be found on the ELP log file.
