Detailed Description

OpenGL backend implementation of RPass.

Renders into an RSurface backed by an RGLImage using RGLPainter and/or Skia. It makes the target image's EGL context/surface current on demand and, when switching between the RPainter and SkCanvas APIs, flushes pending commands and resets the shared GL state so the two do not interfere. Created via RSurface::beginPass().

Constructor & Destructor Documentation

~RGLPass()

~RGLPass ( )

noexcept

Destroys the pass, flushing any pending Skia commands if the SkCanvas API was last used.

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.
