gfx_coord_t gfx_get_height

(

void

)

Return the current height of the screen.

Return the current height of the screen for the current orientation. Screen can be rotated runtime on supported displays with gfx_set_orientation.

Returns

Height of the screen in pixels.

gfx_coord_t gfx_get_width

(

void

)

Return the current width of the screen.

Return the current width of the screen for the current orientation. Screen can be rotated runtime on supported displays with gfx_set_orientation.

Returns

Width of the screen in pixels.

References gfx_width.

void gfx_set_clipping	(	gfx_coord_t	min_x,
		gfx_coord_t	min_y,
		gfx_coord_t	max_x,
		gfx_coord_t	max_y
	)

Set the clipping region.

Set the clipping region for all subsequent graphics operations. Nothing will be drawn outside the clipping region. Clipping is handled in software, and is enabled with CONF_GFX_USE_CLIPPING.

Parameters

min_x	Left edge of region.
min_y	Top edge of region.
max_x	Right edge of region.
max_y	Bottom edge of region.
