Struct TextureBlitter

pub struct TextureBlitter { /* private fields */ }

Texture Blitting (Copying) Utility

Use this if you want to just render/copy texture A to texture B where CommandEncoder::copy_texture_to_texture would not work because:

• Textures are in incompatible formats.
• Textures are of different sizes.
• Your copy destination is the surface texture and does not have the COPY_DST usage.

Implementations

impl TextureBlitter

pub fn new(device: &Device, format: TextureFormat) -> Self

Returns a TextureBlitter with default settings.

Arguments

• device - A Device
• format - The TextureFormat of the texture that will be copied to. This has to have the RENDER_TARGET usage.

Properties of the blitting (such as the BlendState) can be customised by using TextureBlitterBuilder instead.

pub fn copy( &self, device: &Device, encoder: &mut CommandEncoder, source: &TextureView, target: &TextureView, )

Copies the data from the source TextureView to the target TextureView

Arguments

• device - A Device
• encoder - A CommandEncoder
• source - A TextureView that gets copied. The format does not matter.
• target - A TextureView that gets the data copied from the source. It has to be the same format as the format specified in TextureBlitter::new
