Function Documentation

void FrameBuffer_init (  int  w, int  h, int  orientation, int  flags )

Initializes the FrameBuffer system. This system sets up the native MoSync framebuffer, so make sure that it isn't in use while using this system. Parameters: w  The width in pixels of the framebuffer. h  The height in pixels of the framebuffer. orientation  The orientation of the the screen. flags  Flags for setting bits per pixel.

void FrameBuffer_setOrientation (  int  orientation  )

Sets the orientation of the framebuffer. Parameters: orientation  The new orientation of the framebuffer.

int FrameBuffer_getOrientation (  void   )

Gets the orientation of the framebuffer. Returns: The current orientation.

void FrameBuffer_close (  void   )

Closes the framebuffer.

void FrameBuffer_setPalette (  int  startDst, int  startSrc, int  num, const byte *  src, int  flags )

Sets a part of the palette. Parameters: startDst  Where to start in the destination palette (offset in color elements). startSrc  Where to start in the src palette (offset in bytes); num  How many colors should be set. src  The source palette on the format, in bytes, RGBRGB... (note that if FLAG_RGB666 is set then each color component is only 6 bits). flags  If FLAG_RGB666 then 6 bits will be used per component.

void FrameBuffer_setPaletteEntry (  int  i, int  r, int  g, int  b, int  flags )

Sets a single palette entry. Parameters: i  The index of the color to be set. r  The red color component. g  The green color component. b  The blue color component. flags  If FLAG_RGB666 then 6 bits will be used per component.

void FrameBuffer_getPaletteEntry (  int  i, byte *  dst, int  flags )

Gets a single palette entry. Parameters: i  The index of the color to be recieved. dst  A pointer to the destination memory. (3 bytes) flags  If FLAG_RGB666 then 6 bits will be used per component.

void FrameBuffer_copyRect (  short  x, short  y, short  w, short  h, int  dstx, int  dsty, const byte *  buf, int  pitch )

Blits a part of the the framebuffer to the screen. Parameters: x  The topleft x-coordinate of the rectangle to be copied to screen. y  The topleft y-coordinate of the rectangle to be copied to screen. w  The width of the rectangle to be copied to screen. h  The height of the rectangle to be copied to screen. dstx  The topleft x-coordinate of the destination (in the same coordinate system as x and y). dsty  The topleft y-coordinate of the destination (in the same coordinate system as x and y). buf  Pointer to the source framebuffer. pitch  The pitch of the source framebuffer.

int FrameBuffer_getArrowKeyForOrientation (  int  mak  )

Function to rotate the arrow keys depending on the orientation. Parameters: mak  The mak keycode of the arrow key.

int FrameBuffer_getArrowKeyForOrientationInitial (  int  mak, int  initial )
