Public Methods
::fidl::internal::WireThenable< ::fuchsia_ui_composition::Screenshot::Take> Take (::fuchsia_ui_composition::wire::ScreenshotTakeRequest ScreenshotTakeRequest)Collects the current graphical content of a display in a specified buffer `format` in the
sRGB color space. Note that the sRGB color space is non-linear, meaning that unit tests
doing pixel equality checks making use of non-fully saturated colors should convert to a
linear color space.
See https://fuchsia.dev/fuchsia-src/concepts/ui/scenic/color_spaces for more information.
Screenshot is taken immediately, populated with the display's content from the most recent
VSYNC.
If the client calls [`Take`] a second time before a first [`Take`] call returns, the server
will close the Screenshot connection with a ZX_ERR_SHOULD_WAIT epitaph.
If capture fails due to an internal error, the server will close the Screenshot connection
with a ZX_ERR_INTERNAL epitaph.
Allocates 40 bytes of request buffer on the stack. The callback is stored on the heap.
::fidl::internal::WireThenable< ::fuchsia_ui_composition::Screenshot::TakeFile> TakeFile (::fuchsia_ui_composition::wire::ScreenshotTakeFileRequest ScreenshotTakeFileRequest)Collects the current graphical content of a display in a specified buffer `format` in the
sRGB color space. Note that the sRGB color space is non-linear, meaning that unit tests
doing pixel equality checks making use of non-fully saturated colors should convert to a
linear color space.
TODO(https://fxbug.dev/42065844): Link to fuchsia.dev documentation when it's up.
Screenshot is taken immediately, populated with the display's content from the most recent
VSYNC.
If the client calls [`TakeFile`] a second time before a first [`TakeFile`] call returns,
the server will close the Screenshot connection with a ZX_ERR_SHOULD_WAIT epitaph.
If capture fails due to an internal error, the server will close the Screenshot connection
with a ZX_ERR_INTERNAL epitaph.
This call should be used if the client is on the host and does not support VMOs,
as is the case for ffx tools.
