	DlWimpImageFromPicture (int width, int height, sk_sp< flutter::DisplayList > display_list)

Public Member Functions inherited from Skwasm::DlWimpImageBase
	DlWimpImageBase (int width, int height)
bool	isOpaque () const override
	If the pixel format of this image ignores alpha, this returns true. This method might conservatively return false when it cannot guarnatee an opaque image, for example when the pixel format of the image supports alpha but the image is made up of entirely opaque pixels.
bool	isUIThreadSafe () const override
	If the underlying platform image held by this object has no threading requirements for the release of that image (or if arrangements have already been made to forward that image to the correct thread upon deletion), this method returns true.
flutter::DlColorSpace	GetColorSpace () const override
	Gets the color space of the image.
virtual	~DlWimpImageBase ()
flutter::DlISize	GetSize () const override
size_t	GetApproximateByteSize () const override
Public Member Functions inherited from impeller::DlImageImpeller
Type	GetImageType () const override
	Returns the backend type of this image.
const DlImageImpeller *	asImpellerImage () const override
	Safe downcast to DlImageImpeller.
bool	isTextureBacked () const override
	Returns true if the image is backed by a GPU texture.
