Expand description

9 patch data on top of an Image, which is used to create dynamically stretchable images.

Fields

image: Image

The Image this Patch operates on.

h_stretch: SmallVec<[(f32, f32); 2]>

Horizontally stretchable regions in the 9 patch image. Every element is a pair of begin and end of the stretchable region. Defined in relative coordinates: 0.0 is the left side of the image, 1.0 is the right side of the image.

v_stretch: SmallVec<[(f32, f32); 2]>

Vertically stretchable regions in the 9 patch image. Every element is a pair of begin and end of the stretchable region. Defined in relative coordinates: 0.0 is the top side of the image, 1.0 is the bottom side of the image.

h_content: (f32, f32)

Horizontal content area in the 9 patch image. Content can be placed in the region defined here. Defined in relative coordinates: 0.0 is the left side of the image, 1.0 is the right side of the image.

v_content: (f32, f32)

Vertical content area in the 9 patch image. Content can be placed in the region defined here. Defined in relative coordinates: 0.0 is the top side of the image, 1.0 is the bottom side of the image.

Implementations

impl Patch[src]

pub fn measure_with_content(&self, measured_content: Rectangle) -> Rectangle[src]

Extend measured_content so it exactly fills the content rect of this patch.

pub fn margin(&self) -> Rectangle[src]

Returns the padding of the 9 patch

pub fn minimum_size(&self) -> (f32, f32)[src]

The size of the patch when the content rect is zero sized.

pub fn content_rect(&self, span: Rectangle) -> Rectangle[src]

The content rect for a give size
