Struct i_slint_core::graphics::SharedPixelBuffer
source · [−]#[repr(C)]pub struct SharedPixelBuffer<Pixel> { /* private fields */ }
Expand description
SharedPixelBuffer is a container for storing image data as pixels. It is internally reference counted and cheap to clone.
You can construct a new empty shared pixel buffer with SharedPixelBuffer::new
,
or you can clone it from an existing contiguous buffer that you might already have, using
SharedPixelBuffer::clone_from_slice
.
See the documentation for Image
for examples how to use this type to integrate
Slint with external rendering functions.

sourcepub fn new(width: u32, height: u32) -> Self
pub fn new(width: u32, height: u32) -> Self
Creates a new SharedPixelBuffer with the given width and height. Each pixel will be initialized with the value
that Default::default()
returns for the Pixel type.

sourcepub fn clone_from_slice<SourcePixelType>(
pixel_slice: &[SourcePixelType],
width: u32,
height: u32
) -> Self where
[SourcePixelType]: AsPixels<Pixel>,
pub fn clone_from_slice<SourcePixelType>(
pixel_slice: &[SourcePixelType],
width: u32,
height: u32
) -> Self where
[SourcePixelType]: AsPixels<Pixel>,
Creates a new SharedPixelBuffer by cloning and converting pixels from an existing slice. This function is useful when another crate was used to allocate an image and you would like to convert it for use in Slint.
