Summary ImageBuffer::copyImage consumes GPUP memory and is redundant
Kimmo Kinnunen
Reported 2022-05-31 06:14:52 PDT
ImageBuffer::copyImage consumes GPUP memory and is redundant ImageBuffer::copyImage overrides: - Always ends up returning BitmapImage - Always ends up constructing BitmapImage from copyNativeImage - Is implemented erroneously in many backends, ignoring the preserve resolution scale flag - Is implemented correctly in ImageBufferCGBackend, but will allocate the destination buffer when trying to honour the PreserveResolution::No. This will cause a large unattributed allocation in GPUP
