Struct uefi::proto::console::gop::GraphicsOutput

pub struct GraphicsOutput(/* private fields */);

Provides access to the video hardware’s frame buffer.

The GOP can be used to set the properties of the frame buffer, and also allows the app to access the in-memory buffer.

Implementations

impl GraphicsOutput

pub fn query_mode(&self, index: u32, bs: &BootServices) -> Result<Mode>

Returns information for an available graphics mode that the graphics device and the set of active video output devices supports.

pub fn modes<'a>(&'a self, bs: &'a BootServices) -> ModeIter<'_>

Returns information about all available graphics modes.

pub fn set_mode(&mut self, mode: &Mode) -> Result

Sets the video device into the specified mode, clearing visible portions of the output display to black.

This function will invalidate the current framebuffer.

pub fn blt(&mut self, op: BltOp<'_>) -> Result

Performs a blt (block transfer) operation on the frame buffer.

Every operation requires different parameters.

pub const fn current_mode_info(&self) -> ModeInfo

Returns the frame buffer information for the current mode.

pub fn frame_buffer(&mut self) -> FrameBuffer<'_>

Access the frame buffer directly
