Detailed Description

Vulkan render pass.

Multiplexes an RVKPainter and a Skia SkCanvas over the same VkImage. On destruction it flushes and submits any deferred Skia work so the rendering is realized on the queue before the base RPass publishes the image's write RSync (an empty submit ordered after it on the same queue), then reconciles the image's tracked VkImageLayout with Skia's.

Member Function Documentation

getCanvas()

SkCanvas * getCanvas ( bool  sync = true ) const

overridevirtualnoexcept

Returns the SkCanvas associated with this pass, if available.

Parameters

sync	Whether to synchronize and prepare the canvas for rendering. Pass false only if you intend to update canvas parameters without rendering.

Returns

A pointer to the SkCanvas, or nullptr if SkCanvas is not supported by this pass.

Implements RPass.

getPainter()

RPainter * getPainter ( bool  sync = true ) const

overridevirtualnoexcept

Returns the RPainter associated with this pass, if available.

Parameters

sync	Whether to synchronize and prepare the painter for rendering. Pass false only if you intend to update painter parameters without rendering.

Returns

A pointer to the RPainter, or nullptr if RPainter is not supported by this pass.

Implements RPass.

setGeometry()

void setGeometry ( const RSurfaceGeometry &  geometry )

overridevirtualnoexcept

Sets transformation matrices.

Updates both SkCanvas and RPainter transformation matrices to align with the given surface geometry.

Parameters

geometry

The geometry to apply.

Implements RPass.
