Struct directwrite::text_renderer::TextRenderer

#[repr(transparent)]
pub struct TextRenderer { /* fields omitted */ }

A generic Text Renderer object.

Methods

impl TextRenderer

pub fn new(renderer: impl CustomTextRenderer) -> TextRenderer

Create a text renderer from an application-implemented interface.

pub fn draw_glyph_run(&mut self, context: &DrawGlyphRun) -> DWResult<()>

Draws a run of glyphs using this text renderer. Normally you won't call this directly, but it will be called indirectly from TextLayout::draw

pub fn draw_underline(&mut self, context: &DrawUnderline) -> DWResult<()>

Draws a section of underline using this text renderer. Normally you won't call this directly, but it will be called indirectly from TextLayout::draw

pub fn draw_strikethrough(
    &mut self,
    context: &DrawStrikethrough
) -> DWResult<()>

Draws a section of strikethrough using this text renderer. Normally you won't call this directly, but it will be called indirectly from TextLayout::draw

pub fn draw_inline_object(&mut self, context: &DrawInlineObject) -> DWResult<()>

Draws an inline object using this text renderer. Normally you won't call this directly, but it will be called indirectly from TextLayout::draw

Methods from Deref<Target = PixelSnapping>

pub fn pixel_snapping_disabled(&self, context: &DrawContext) -> DWResult<bool>

Determines whether this object wants pixel snapping to be disabled.

pub fn current_transform(&self, context: &DrawContext) -> DWResult<Matrix3x2f>

Gets the transform that should be applied to this text.

pub fn pixels_per_dip(&self, context: &DrawContext) -> DWResult<f32>

Gets the number of physical pixels per DIP currently being used in this renderer.

Trait Implementations

impl Send for TextRenderer

impl Deref for TextRenderer

type Target = PixelSnapping

The resulting type after dereferencing.

fn deref(&self) -> &PixelSnapping

Dereferences the value.

impl ComWrapper for TextRenderer

type Interface = IDWriteTextRenderer

The raw interface type from winapi

unsafe fn get_raw(&self) -> *mut IDWriteTextRenderer

Gets a raw pointer to the interface. Does not increment the reference count

unsafe fn from_raw(ptr: *mut IDWriteTextRenderer) -> Self

Creates a wrapper from the raw pointer. Takes ownership of the pointer for reference counting purposes.

unsafe fn into_raw(self) -> *mut IDWriteTextRenderer

Consumes the wrapper without affecting the reference count

unsafe fn from_ptr(ptr: ComPtr<IDWriteTextRenderer>) -> Self

Creates a wrapper taking ownership of a ComPtr.

unsafe fn into_ptr(self) -> ComPtr<IDWriteTextRenderer>

Unwraps the wrapper into a ComPtr.
