Member Variable Documentation
std::function<void ()> QRhiReadbackResult::completed
Callback that is invoked upon completion, on the thread the QRhi operates on. Can be left set to nullptr
, in which case no callback is invoked.
QByteArray QRhiReadbackResult::data
The buffer or image data.
See also QRhiResourceUpdateBatch::readBackTexture() and QRhiResourceUpdateBatch::readBackBuffer().
QRhiTexture::Format QRhiReadbackResult::format
Valid only for textures, the texture format.
QSize QRhiReadbackResult::pixelSize
Valid only for textures, the size in pixels.
