void screen::set_video_mode ( u_int16  nl,
u_int16  nh,
u_int8  depth = 0,
bool  dbl = false,
bool  fscreen = false 
) [static]

Sets the video mode.

Parameters:
nl X screen resolution.
nh Y screen resolution.
depth desired screen depth.

Definition at line 39 of file screen.cc.

static u_int16 screen::length (  )  [inline, static]

Returns the length of the screen.

Returns:
length of the screen.

Definition at line 63 of file screen.h.

static u_int16 screen::height (  )  [inline, static]

Returns the height of the screen.

Returns:
height of the screen.

Definition at line 71 of file screen.h.

static u_int8 screen::bytes_per_pixel (  )  [inline, static]

Returns the screen depth, in bytes per pixel.

Returns:
screen depth, in bytes per pixel.

Definition at line 79 of file screen.h.

static u_int32 screen::trans_col (  )  [inline, static]

Returns the translucent color in screen's depth format.

For manipulation on images that will only be displayed, this is the right function to call for getting the translucent color.

Returns:
the translucent color in screen's depth format.

Definition at line 89 of file screen.h.

static void screen::clear (  )  [inline, static]

Totally clears the screen with black.

Definition at line 98 of file screen.h.

void screen::show (  )  [static]

Ensure the framebuffer is copied to the physical screen.

Definition at line 110 of file screen.cc.

static bool screen::is_fullscreen (  )  [inline, static]

Returns whether the current mode is fullscreen or windowed.

Returns:
  • true: fullscreen.
  • false: windowed.

Definition at line 112 of file screen.h.

bool screen::set_fullscreen ( bool  m  )  [static]

Sets fullscreen/windowed mode.

Parameters:
mode 
  • true: fullscreen mode.
  • false: windowed mode.
Returns:
  • true if the operation succeed.
  • false if the mode is already set, or the system doesn't support this mode.

Definition at line 149 of file screen.cc.
