## Settings
### default_font
Name of the font to be used when no font is given. The font should be registered.
If no default\_font given or if default\_font given but not registered, the first registered font will be used as default.
## Provided methods
### get\_text\_size
**font\_lib.get\_text\_size(font\_name, text)**
Computes size for a given font and text
### font_api.get_default_font_name()
Returns de default font name.
**font\_name**: Font name of registered font to use
**text**: Text to be rendered
**Returns**: rendered text width, height
###font_api.register_font(font_name, font_def)
Register a new font.
**font_name**: Name of the font to register. If registering different sizes of the same font, add size in the font name (e.g. times_10, times_12...).
**font_def**: Font definition table (see **Font definition table** below).
### make\_line\_texture
**font\_lib.make\_line\_texture(font\_name, text, width, x, y)**
###font_api.on_display_update(pos, objref)
Standard on_display_update entity callback.
Builds texture part for a text line
**pos**: Node position
**font\_name**: Font name of registered font to use
**text**: Text to be rendered
**texturew**: Width of the texture (extra text is not rendered)
**x**: Starting x position in texture
**y**: Vertical position of the line in texture
**Returns**: Texture string
**objref**: Object reference of entity
### make\_multiline\_texture
**font\_lib.make\_multiline\_texture(font\_name, text, width, height, maxlines, halign, valign, color)**
Node should have a corresponding display_entity with size, resolution and maxlines fields and optionally halign, valign and color fields.
Builds texture for a multiline colored text
###Font definition table
Font definition table used by **font_api.register_font** and **font\_api.Font:new** may/can contain following elements:
**font\_name**: Font name of registered font to use
**text**: Text to be rendered
**texturew**: Width of the texture (extra text will be truncated)
**textureh**: Height of the texture
**maxlines**: Maximum number of lines
**halign**: Horizontal text align ("left", "right" or "center") (optional)
**valign**: Vertical text align ("top", "bottom" or "center") (optional)
**color**: Color of the text (optional)
**Returns**: Texture string
* **height** (required): Font height in pixels (all font textures should have the same height) .
* **widths** (required): Array of character widths in pixels, indexed by UTF codepoints.
* **margintop** (optional): Margin (in texture pixels) added on top of each char texture.
* **marginbottom** (optional): Margin (in texture pixels) added at bottom of each char texture.
* **linespacing** (optional): Spacing (in texture pixels) between each lines.
### register\_font
**font\_lib.register_font(font\_name, height, widths)**
Registers a new font in font_api.
**font\_name**: Name of the font to register (this name will be used to address the font later)
If registering different sizes of the same font, add size in the font name (e.g. times\_10, times\_12...).
**height**: Font height in pixels (all font textures should have the same height)
**widths** : Array of character widths in pixels, indexed by UTF codepoints
**margintop**, **marginbottom** and **linespacing** can be negative numbers (default 0) and are to be used to adjust various font styles to each other.
Font must have a char 0 which will be used to display any unknown char.
All textures corresponding to the indexes in **widths** array should be present in textures directory with a name matching the pattern :
All textures corresponding to the indexes in widths array should be present in textures directory with a name matching the pattern :
**font\_<font\_name>_<utf\_code>.png**
> font\_**{font_name}**_**{utf_code}**.png
**<font\_name>**: Name of the font as given in the first argument
**<utf\_code>**: UTF code of the char in 4 hexadecimal digits
**{font\_name}**: Name of the font as given in the first argument
To ease that declaration, a shell is provided to build a <font\_name>.lua file from the texture files (see provided tools).
**{utf\_code}**: UTF code of the char in 4 hexadecimal digits
Example : font_courrier_0041.png is for the "A" char in the "courrier" font.
To ease that declaration (specially to build the **widths** array), a shell is provided to build a {font\_name}.lua file from the texture files (see provided tools).

## Font class
A font usable with font API. This class is supposed to be for internal use but who knows.
### font\_api.Font:new(def)
Create a new font object.
**def** is a table containing font definition. See **Font definition table** above.
### font:get_char_width(char)
Returns the width of char **char** in texture pixels.
**char**: Unicode codepoint of char.
### font:get_height(nb_of_lines)
Returns line(s) height. Takes care of top and bottom margins and line spacing.
**nb_of_lines**: Number of lines in the text.
### font:get_width(line)
Returns the width of a text line. Beware, if line contains any new line char, they are ignored.
**line**: Line of text which the width will be computed.
### font:make_line_texture(line, texturew, x, y)
Create a texture for a text line.
**line**: Line of text to be rendered in texture.
**texturew**: Width of the texture (extra text is not rendered).
**x**: Starting x position in texture.
**y**: Vertical position of the line in texture.
### font:make_text_texture(text, texturew, textureh, maxlines, halign, valign, color)
Builds texture for a multiline colored text.
**text**: Text to be rendered.
**texturew**: Width of the texture (extra text will be truncated).
**textureh**: Height of the texture.
**maxlines**: Maximum number of lines.
**halign**: Horizontal text align ("left"/"center"/"right") (optional).
**valign**: Vertical text align ("top"/"center"/"bottom") (optional).
**color**: Color of the text (optional).
