pango_font_description_from_string (
const char* str
)
Description [src]
Creates a new font description from a string representation.
The string must have the form
"[FAMILY-LIST] [STYLE-OPTIONS] [SIZE] [VARIATIONS]",
where FAMILY-LIST is a comma-separated list of families optionally terminated by a comma, STYLE_OPTIONS is a whitespace-separated list of words where each word describes one of style, variant, weight, stretch, or gravity, and SIZE is a decimal number (size in points) or optionally followed by the unit modifier “px” for absolute size. VARIATIONS is a comma-separated list of font variation specifications of the form @axis=value (the = sign is optional).
The following words are understood as styles: “Normal”, “Roman”, “Oblique”, “Italic”.
The following words are understood as variants: “Small-Caps”, “All-Small-Caps”, “Petite-Caps”, “All-Petite-Caps”, “Unicase”, “Title-Caps”.
The following words are understood as weights: “Thin”, “Ultra-Light”, “Extra-Light”, “Light”, “Semi-Light”, “Demi-Light”, “Book”, “Regular”, “Medium”, “Semi-Bold”, “Demi-Bold”, “Bold”, “Ultra-Bold”, “Extra-Bold”, “Heavy”, “Black”, “Ultra-Black”, “Extra-Black”.
The following words are understood as stretch values: “Ultra-Condensed”, “Extra-Condensed”, “Condensed”, “Semi-Condensed”, “Semi-Expanded”, “Expanded”, “Extra-Expanded”, “Ultra-Expanded”.
The following words are understood as gravity values: “Not-Rotated”, “South”, “Upside-Down”, “North”, “Rotated-Left”, “East”, “Rotated-Right”, “West”.
Any one of the options may be absent. If FAMILY-LIST is absent, then
the family_name field of the resulting font description will be
initialized to NULL. If STYLE-OPTIONS is missing, then all style
options will be set to the default values. If SIZE is missing, the
size in the resulting font description will be set to 0.
A typical example:
"Cantarell Italic Light 15 @wght=200".
