Struct image::image::SubImageInner

pub struct SubImageInner<I> {
    image: I,
    xoffset: u32,
    yoffset: u32,
    xstride: u32,
    ystride: u32,
}

The inner type of SubImage that implements GenericImage{,View}.

This type is nominally pub but it is not exported from the crate. It should be regarded as an existential type in any case.

Fields

image: I

xoffset: u32

yoffset: u32

xstride: u32

ystride: u32

Trait Implementations

impl<I: Clone> Clone for SubImageInner<I>

fn clone(&self) -> SubImageInner<I>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I> GenericImage for SubImageInner<I>where I: DerefMut, I::Target: GenericImage + Sized,

fn blend_pixel(&mut self, x: u32, y: u32, pixel: Self::Pixel)

👎Deprecated since 0.24.0: Use iterator pixels_mut to blend the pixels directly

DEPRECATED: This method will be removed. Blend the pixel directly instead.

fn get_pixel_mut(&mut self, x: u32, y: u32) -> &mut Self::Pixel

👎Deprecated since 0.24.0: Use get_pixel and put_pixel instead.

Gets a reference to the mutable pixel at location (x, y). Indexed from top left.

fn put_pixel(&mut self, x: u32, y: u32, pixel: Self::Pixel)

Put a pixel at location (x, y). Indexed from top left.

unsafe fn unsafe_put_pixel(&mut self, x: u32, y: u32, pixel: Self::Pixel)

Puts a pixel at location (x, y). Indexed from top left.

fn copy_from<O>(&mut self, other: &O, x: u32, y: u32) -> ImageResult<()>where O: GenericImageView<Pixel = Self::Pixel>,

Copies all of the pixels from another image into this image.

fn copy_within(&mut self, source: Rect, x: u32, y: u32) -> bool

Copies all of the pixels from one part of this image to another part of this image.

fn sub_image( &mut self, x: u32, y: u32, width: u32, height: u32 ) -> SubImage<&mut Self>where Self: Sized,

Returns a mutable subimage that is a view into this image. If you want an immutable subimage instead, use GenericImageView::view The coordinates set the position of the top left corner of the SubImage.

impl<I> GenericImageView for SubImageInner<I>where I: Deref, I::Target: GenericImageView,

type Pixel = <<I as Deref>::Target as GenericImageView>::Pixel

The type of pixel.

fn dimensions(&self) -> (u32, u32)

The width and height of this image.

fn bounds(&self) -> (u32, u32, u32, u32)

👎Deprecated: This method has inconsistent behavior between implementations (#1829). Use dimensions instead

The bounding rectangle of this image.

fn get_pixel(&self, x: u32, y: u32) -> Self::Pixel

Returns the pixel located at (x, y). Indexed from top left.

fn width(&self) -> u32

The width of this image.

fn height(&self) -> u32

The height of this image.

fn in_bounds(&self, x: u32, y: u32) -> bool

Returns true if this x, y coordinate is contained inside the image.

unsafe fn unsafe_get_pixel(&self, x: u32, y: u32) -> Self::Pixel

Returns the pixel located at (x, y). Indexed from top left.

fn pixels(&self) -> Pixels<'_, Self> where Self: Sized,

Returns an Iterator over the pixels of this image. The iterator yields the coordinates of each pixel along with their value

fn view(&self, x: u32, y: u32, width: u32, height: u32) -> SubImage<&Self>where Self: Sized,

Returns a subimage that is an immutable view into this image. You can use GenericImage::sub_image if you need a mutable view instead. The coordinates set the position of the top left corner of the view.
