Implementations§
Source§impl MemoryTexture
impl MemoryTexture
Sourcepub fn new(
width: i32,
height: i32,
format: MemoryFormat,
bytes: &Bytes,
stride: usize,
) -> MemoryTexture
pub fn new( width: i32, height: i32, format: MemoryFormat, bytes: &Bytes, stride: usize, ) -> MemoryTexture
Creates a new texture for a blob of image data.
The GBytes
must contain @stride × @height pixels
in the given format.
§width
the width of the texture
§height
the height of the texture
§format
the format of the data
§bytes
the GBytes
containing the pixel data
§stride
rowstride for the data
§Returns
A newly-created Texture
