Struct Patch

pub struct Patch {
    pub image: ImageData,
    pub h_stretch: SmallVec<[(f32, f32); 2]>,
    pub v_stretch: SmallVec<[(f32, f32); 2]>,
    pub h_content: (f32, f32),
    pub v_content: (f32, f32),
}

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

Fields

image: ImageData

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

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

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

pub fn margin(&self) -> Rectangle

Returns the padding of the 9 patch

pub fn minimum_size(&self) -> (f32, f32)

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

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

The content rect for a give size

Trait Implementations

impl Clone for Patch

fn clone(&self) -> Patch

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Patch

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
