Methods

static quint64 estimatedBytes(const QSize& logicalSize, qreal devicePixelRatio)

Conservative current-context target bytes, or zero when unsupported. Includes the actual driver MSAA count; performs at most a tiny context probe.

bool render(qreal devicePixelRatio, quint64 maximumBytes = 67108864)

Render/reuse the current frame within the byte limit; false restores CPU. DPR must be finite and in (0, 4]. The default per-layer limit is 64 MiB.

unsigned int textureId() const

Borrowed premultiplied RGBA, bottom-up OpenGL texture; zero when inactive. Valid only in the current context until release, resize or context replacement.

void release()

Release GPU resources and resume the source's unchanged CPU state.
