	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.

◆ get_error()

std::optional< std::string > flutter::DlDeferredImageGPUSkia::get_error ( ) const

overridevirtual

Returns: An error, if any, that occurred when trying to create the image.

Reimplemented from flutter::DlImage.

Definition at line 89 of file display_list_deferred_image_gpu_skia.cc.

                                                               {

}

◆ GetApproximateByteSize()

size_t flutter::DlDeferredImageGPUSkia::GetApproximateByteSize ( ) const

overridevirtual

◆ isOpaque()

bool flutter::DlDeferredImageGPUSkia::isOpaque ( ) const

overridevirtual

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.

Returns: True if the pixel format of this image ignores alpha.

◆ isUIThreadSafe()

bool flutter::DlDeferredImageGPUSkia::isUIThreadSafe ( ) const

overridevirtual

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.

Returns: True if the underlying image is held in a thread-safe manner.

Implements flutter::DlImage.
