Struct D3D12TextureBuilder 

pub struct D3D12TextureBuilder { /* private fields */ }

Available on crate feature v4_20 only.

D3D12TextureBuilder is a builder used to construct gdk::Texture objects from ID3D12Resources.

The operation of D3D12TextureBuilder is quite simple: Create a texture builder, set all the necessary properties, and then call Gdk::D3d12TextureBuilder::build() to create the new texture.

Not all D3D12Resources can be used. You have to use a texture resource for a gdk::Texture. GDK will attempt to detect invalid resources and fail to create the texture in that case.

D3D12TextureBuilder can be used for quick one-shot construction of textures as well as kept around and reused to construct multiple textures.

Properties

color-state

The color state of the texture.

Readable | Writeable

fence

The optional ID3D12Fence to wait on before using the resource.

Readable | Writeable

fence-wait

The value the fence should wait on

Readable | Writeable

premultiplied

Whether the alpha channel is premultiplied into the others.

Only relevant if the format has alpha.

Readable | Writeable

GLib type: GObject with reference counted clone semantics.

Implementations

impl D3D12TextureBuilder

pub fn new() -> D3D12TextureBuilder

Creates a new texture builder.

Returns

the new GdkTextureBuilder

pub fn color_state(&self) -> Option<ColorState>

Gets the color state previously set via gdk_d3d12_texture_builder_set_color_state().

Returns

the color state

pub fn fence_wait(&self) -> u64

Returns the value that GTK should wait for on the fence before using the resource.

Returns

the fence wait value

pub fn is_premultiplied(&self) -> bool

Whether the data is premultiplied.

Returns

whether the data is premultiplied

pub fn update_region(&self) -> Option<Region>

Gets the region previously set via gdk_d3d12_texture_builder_set_update_region() or None if none was set.

Returns

The region

pub fn update_texture(&self) -> Option<Texture>

Gets the texture previously set via gdk_d3d12_texture_builder_set_update_texture() or None if none was set.

Returns

The texture

pub fn set_color_state(&self, color_state: Option<&ColorState>)

Sets the color state for the texture.

By default, the colorstate is NULL. In that case, GTK will choose the correct colorstate based on the format. If you don’t know what colorstates are, this is probably the right thing.

color_state

a gdk::ColorState or NULL to unset the colorstate.

pub fn set_fence_wait(&self, fence_wait: u64)

Sets the value that GTK should wait on on the given fence before using the resource.

When no fence is set, this value has no effect.

fence_wait

the value to wait on

pub fn set_premultiplied(&self, premultiplied: bool)

Sets whether the data is premultiplied.

Unless otherwise specified, all formats including alpha channels are assumed to be premultiplied.

premultiplied

whether the data is premultiplied

pub fn set_update_region(&self, region: Option<&Region>)

Sets the region to be updated by this texture. Together with [update-texture][struct@crate::Gdk::D3d12TextureBuilder#update-texture] this describes an update of a previous texture.

When rendering animations of large textures, it is possible that consecutive textures are only updating contents in parts of the texture. It is then possible to describe this update via these two properties, so that GTK can avoid rerendering parts that did not change.

An example would be a screen recording where only the mouse pointer moves.

region

the region to update

pub fn set_update_texture(&self, texture: Option<&impl IsA<Texture>>)

Sets the texture to be updated by this texture. See Gdk::D3d12TextureBuilder::set_update_region() for an explanation.

texture

the texture to update

Trait Implementations

impl Clone for D3D12TextureBuilder

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for D3D12TextureBuilder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for D3D12TextureBuilder

fn default() -> Self

Returns the “default value” for a type.

impl HasParamSpec for D3D12TextureBuilder

type ParamSpec = ParamSpecObject

type SetValue = D3D12TextureBuilder

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(&str) -> ParamSpecObjectBuilder<'_, D3D12TextureBuilder>
