		int16_t	dst_x0,
		int16_t	dst_y0
	)

virtual

Draw a rectangle represented in the device's native color format.

Source data pointer correspond to the (0, 0) point in the source coordinate system, with stride of row_width_bytes. The source rectangle at (src_x0, src_y0, src_x1, src_y1) relative to the data pointer, gets copied to the destination rectangle with top-left corner at (dst_x0, dst_y0). The caller must ensure that the destination rectangle fits within the device's bounds.

The default implementation processes the rectangle by small tiles, converting the data to an array of regular colors, and calling regular window functions to draw them. Specific devices can override this method to provide a more efficient implementation that draws directly from the source data.

	)

virtual

Asynchronous variant of drawDirectRect().

This method may continue executing after it returns. The caller must keep data valid until any subsequent drawing method call or until flush() is called.

The default implementation calls drawDirectRect() synchronously.

◆ end()

virtual void roo_display::DisplayOutput::end ( )

inlinevirtual

Finalize the previously entered write transaction, flushing any pending writes.

Normally called by the DrawingContext destructor, and does not need to be called explicitly.

Reimplemented in roo_display::OffscreenDevice< ColorMode, pixel_order, byte_order, pixels_per_byte, storage_type >, roo_display::OffscreenDevice< ColorMode, ColorPixelOrder::kMsbFirst, roo_io::kBigEndian, ColorTraits< ColorMode >::pixels_per_byte, ColorStorageType< ColorMode > >, roo_display::OffscreenDevice< Monochrome, ColorPixelOrder::kMsbFirst, roo_io::kBigEndian, ColorTraits< Monochrome >::pixels_per_byte, ColorStorageType< Monochrome > >, roo_display::OffscreenDevice< typename Target::ColorMode >, roo_display::AddrWindowDevice< Target >, roo_display::AddrWindowDevice< pinLcdCs, pinLcdDc, -1 >, roo_display::BufferedAddrWindowDevice< Target >, and roo_display::BackgroundFillOptimizerDevice.

◆ fill()

void roo_display::DisplayOutput::fill	(	Color	color,
		uint32_t	pixel_count
	)

virtual

Write pixel_count copies of the same color into the current address window.

The same preconditions as write() apply: the address must be set via setAddress() and not invalidated by any of the write* / fill* methods. Otherwise, the behavior is undefined.

Default implementation falls back to chunked write(). Drivers and filters can override this for a more efficient single-color path.
