Struct ImageViewMut 

pub struct ImageViewMut<'a> { /* private fields */ }

A borrowed mutable slice of image data.

Implementations

impl<'a> ImageViewMut<'a>

pub fn new(data: &'a mut [u8], size: Size, color: ColorFormat) -> Option<Self>

Creates a new contiguous image view from the given data, size, and color format.

The data must be the correct size for the given size and color format. If data.len() != size.pixels() * color.bytes_per_pixel(), then None is returned.

pub fn new_with( data: &'a mut [u8], row_pitch: usize, size: Size, color: ColorFormat, ) -> Option<Self>

Creates a new image view from the given data, row pitch, size, and color format.

The data and row pitch must be the correct size for the given size and color format. If row_pitch < width * color.bytes_per_pixel() or the data length is too short, then None will be returned.

Note: The data slice will be truncated to the exact addressable length based on row pitch and size.

pub fn data(&mut self) -> &mut [u8]

pub fn size(&self) -> Size

pub fn width(&self) -> u32

pub fn height(&self) -> u32

pub fn color(&self) -> ColorFormat

pub fn row_pitch(&self) -> usize

pub fn is_contiguous(&self) -> bool

Returns true if the data is contiguous in memory.

pub fn cropped(self, offset: Offset, size: Size) -> Self

Returns a new image view that is a cropped version of this image.

Panics

If the rectangle is not within the bounds of the image size.
