Texture UV

Added: 1.0.0

An interface representing the UV mapping of a texture. It maps texture coordinates normalized as floats from 0.0f to 1.0f to determine how textures are rendered onto shapes.

Use the static factory methods createFromRegion() or createFromUV() to instantiate a new definition.

static TextureUV createFromRegion(
    int atlasWidth, int atlasHeight,
    @Nullable Rectangle region)

Static factory method that instantiates a new instance by converting texture region into normalized floating-point UV coordinates.

• Atlas Width: The total width of the texture file in pixels.
• Atlas Height: The total height of the texture file in pixels.
• Region: The bounding box sub-region defining the pixel coordinates to map. Pass null to use the whole texture bounds (0.0f to 1.0f).

static TextureUV createFromUV(
    float u_min, float u_max,
    float v_min, float v_max)

Static factory method that instantiates a new instance using pre-calculated, raw normalized floating-point UV coordinates.

• U Min: The minimum horizontal coordinate (the left edge).
• U Max: The maximum horizontal coordinate (the right edge).
• V Min: The minimum vertical coordinate (the top edge).
• V Max: The maximum vertical coordinate (the bottom edge).
