Struct TextureSlicer 

Source
pub struct TextureSlicer {
    pub border: BorderRect,
    pub center_scale_mode: SliceScaleMode,
    pub sides_scale_mode: SliceScaleMode,
    pub max_corner_scale: f32,
}
Expand description

Slices a texture using the 9-slicing technique. This allows to reuse an image at various sizes without needing to prepare multiple assets. The associated texture will be split into nine portions, so that on resize the different portions scale or tile in different ways to keep the texture in proportion.

For example, when resizing a 9-sliced texture the corners will remain unscaled while the other sections will be scaled or tiled.

See 9-sliced textures.

Fields§

§border: BorderRect

Inset values in pixels that define the four slicing lines dividing the texture into nine sections.

§center_scale_mode: SliceScaleMode

Defines how the center part of the 9 slices will scale

§sides_scale_mode: SliceScaleMode

Defines how the 4 side parts of the 9 slices will scale

§max_corner_scale: f32

Defines the maximum scale of the 4 corner slices (default to 1.0)

Implementations§

Source§

impl TextureSlicer

Source

pub fn compute_slices( &self, rect: Rect, render_size: Option<Vec2>, ) -> Vec<TextureSlice>

Slices the given rect into at least 9 sections. If the center and/or side parts are set to tile, a bigger number of sections will be computed.

§Arguments
  • rect - The section of the texture to slice in 9 parts
  • render_size - The optional draw size of the texture. If not set the rect size will be used.
