Contains information about a single character in a run (input string). The information indicates if the character glyph is affected by surrounding letters of the run.
Syntax
typedef struct script_charprop {
WORD fCanGlyphAlone : 1;
WORD reserved : 15;
} SCRIPT_CHARPROP;
Members
fCanGlyphAlone
Value indicating if the shaping of a letter depends on other characters around the letter being shaped. Possible values are defined in the following table.
| Value | Meaning |
|---|---|
| TRUE | The shape of a letter is independent of surrounding characters. |
| FALSE | The shape of a letter depends on one or more adjacent characters. |
reserved
Reserved.
Remarks
One or more characters in a run, immediately preceding and/or following the letter being shaped, can influence shaping. Information about these characters can help optimize higher-level layout code, such as that used to optimize paragraph layout.
Examples
Let's look at an example of the use of this structure.
- A font has ligatures for letter combinations "fi" and "fl", and no others.
- The input string is "I like flying fish".
- An array of SCRIPT_CHARPROP structures contains one structure for each character of the input string.
