Struct ImageFontDescriptor

Source 
pub struct ImageFontDescriptor { /* private fields */ }
Expand description

On-disk representation of an ImageFont, optimized to make it easy for humans to write these. See the docs for ImageFontLayout’s variants for information on how to write the syntax, or [the example font’s RON asset].

Implementations§

Source§

impl ImageFontDescriptor

Source

pub fn new( image: Utf8PathBuf, layout: ImageFontLayout, ) -> Result<Self, ImageFontDescriptorValidationError>

Creates a new ImageFontDescriptor instance with the provided image path and font layout, performing validation to ensure the descriptor is valid.

§Parameters
  • image: The path to the image file containing the font glyphs, relative to the RON file that described the font. This should be a valid path to a texture file that can be loaded by the asset system.
  • layout: The layout description of the font, specifying how characters map to regions within the image. See ImageFontLayout for more details about the available layout configurations.
§Returns

A new ImageFontDescriptor instance if validation succeeds.

§Errors

Returns an ImageFontDescriptorValidationError if the provided values do not pass validation.

Source

pub fn image(&self) -> &Utf8Path

Gets the path to the image file containing the font glyphs.

This is the value of the image field. The path is relative to the RON file and should point to a valid texture file.

§Returns

A reference to the Utf8PathBuf containing the image file path.

Source

pub fn layout(&self) -> &ImageFontLayout

Gets the layout description of the font.

This is the value of the layout field, which specifies how characters map to regions within the image. See ImageFontLayout for details about the available variants.

§Returns

A reference to the ImageFontLayout describing the font layout.
