◆ createDevice()

sk_sp< SkDevice > skgpu::ganesh::Device::createDevice	(	const CreateInfo &	,

	)

overridevirtual

Create a new device based on CreateInfo. If the paint is not null, then it represents a preview of how the new device will be composed with its creator device (this).

The subclass may be handed this device in drawDevice(), so it must always return a device that it knows how to draw, and that it knows how to identify if it is not of the same subclass (since drawDevice is passed a SkDevice*). If the subclass cannot fulfill that contract (e.g. PDF cannot support some settings on the paint) it should return NULL, and the caller may then decide to explicitly create a bitmapdevice, knowing that later it could not call drawDevice with it (but it could call drawSprite or drawBitmap).

Returns the bounding box of the current clip, in this device's coordinate space. No pixels outside of these bounds will be touched by draws unless the clip is further modified (at which point this will return the updated bounds).

The SkDevice passed will be an SkDevice which was returned by a call to onCreateDevice on this device with kNeverTile_TileExpectation.

The default implementation calls snapSpecial() and drawSpecial() with the relative transform from the input device to this device. The provided SkPaint cannot have a mask filter or image filter, and any shader is ignored.
