Struct veloren_voxygen::render::pipelines::ui::PremultiplyUpload
source · pub(in render) struct PremultiplyUpload {
source_bg: BindGroup,
source_size_xy: u32,
offset: Vec2<u16>,
}
Expand description
An image upload that needs alpha premultiplication and which is in a pending state.
From here we will use the PremultiplyAlpha
pipeline to premultiply the
alpha while transfering the image to its destination texture.
Fields§
§source_bg: BindGroup
§source_size_xy: u32
§offset: Vec2<u16>
The location in the final texture this will be placed at. Technically, we don’t need this information at this point but it is convenient to store it here.
Implementations§
source§impl PremultiplyUpload
impl PremultiplyUpload
pub(in render) fn prepare( device: &Device, queue: &Queue, layout: &PremultiplyAlphaLayout, image: &RgbaImage, offset: Vec2<u16> ) -> Self
sourcepub(in render) fn draw_data(
&self,
target: &Texture
) -> (&BindGroup, PremultiplyAlphaParams)
pub(in render) fn draw_data( &self, target: &Texture ) -> (&BindGroup, PremultiplyAlphaParams)
Semantically, this consumes the PremultiplyUpload
but we need to keep
the bind group alive to the end of the render pass and don’t want to
bother storing it somewhere else.
