Struct epaint::image::ImageDelta

pub struct ImageDelta {
    pub image: ImageData,
    pub options: TextureOptions,
    pub pos: Option<[usize; 2]>,
}

A change to an image.

Either a whole new image, or an update to a rectangular region of it.

Fields

image: ImageData

What to set the texture to.

If Self::pos is None, this describes the whole texture.

If Self::pos is Some, this describes a patch of the whole image starting at Self::pos.

options: TextureOptions

pos: Option<[usize; 2]>

If None, set the whole texture to Self::image.

If Some(pos), update a sub-region of an already allocated texture with the patch in Self::image.

Implementations

impl ImageDelta

pub fn full(image: impl Into<ImageData>, options: TextureOptions) -> Self

Update the whole texture.

pub fn partial( pos: [usize; 2], image: impl Into<ImageData>, options: TextureOptions ) -> Self

Update a sub-region of an existing texture.

pub fn is_whole(&self) -> bool

Is this affecting the whole texture? If false, this is a partial (sub-region) update.

Trait Implementations

impl Clone for ImageDelta

fn clone(&self) -> ImageDelta

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<ImageDelta> for ImageDelta

fn eq(&self, other: &ImageDelta) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
