constexpr v1::glyph_atlas_info::glyph_atlas_info ( point3 position, extent2 size, scale2 border_scale, scale2 texture_coordinate_scale )

inlineconstexprnoexcept

Parameters

position	Pixel coordinate (x, y), z: texture map number.
size	Number of pixels in width and height
border_scale	The amount to scale a polygon to add a border.
texture_coordinate_scale	The amount to scale texel coordinate to UV (0.0-1.0) coordinates.

Field Documentation

border_scale

scale2 v1::glyph_atlas_info::border_scale

The scaling factor used for scaling a quad to include the border.

position

point3 v1::glyph_atlas_info::position

pixel coordinates.

• (x, y): pixel coordinate of left-bottom corner of the glyph in the atlas.
• z: index in the texture map array.

size

extent2 v1::glyph_atlas_info::size

Size of the glyph in pixels in the texture map.

texture_coordinates

aarectangle v1::glyph_atlas_info::texture_coordinates

The position and size of the glyph in the texture in UV coordinates.

The coordinates are relative values between 0.0 - 1.0 between the edges of the texture map.
