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.

References gfx_height.

Referenced by main(), win_hide(), win_init(), win_reset_root_geometry(), wtk_continue_drag(), wtk_start_drag(), and wtk_stop_drag().

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.

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_xLeft edge of region.
min_yTop edge of region.
max_xRight edge of region.
max_yBottom edge of region.
