Private Member Functions
bool	find_hole (int &x, int &y, int x_size, int y_size) const
	Searches for a hole of at least x_size by y_size pixels somewhere within the layout.
const CharPlacement *	find_overlap (int x, int y, int x_size, int y_size) const
	If the rectangle whose top left corner is x, y and whose size is x_size, y_size describes an empty hole that does not overlap any placed chars, returns NULL; otherwise, returns the first placed texture that the image does overlap.

Member Function Documentation

bool CharLayout::find_hole (  int &  x, int &  y, int  x_size, int  y_size )  const [private]

Searches for a hole of at least x_size by y_size pixels somewhere within the layout. If a suitable hole is found, sets x and y to the top left corner and returns true; otherwise, returns false. Definition at line 93 of file charLayout.cxx. References x.

const CharPlacement * CharLayout::find_overlap (  int  x, int  y, int  x_size, int  y_size )  const [private]

If the rectangle whose top left corner is x, y and whose size is x_size, y_size describes an empty hole that does not overlap any placed chars, returns NULL; otherwise, returns the first placed texture that the image does overlap. It is assumed the rectangle lies completely within the boundaries of the image itself. Definition at line 145 of file charLayout.cxx. Referenced by place_character().

bool CharLayout::place_character (  const CharBitmap *  bm  )

Given a character bitmap and font metrics extracted from the pk file, find a place for it on the layout. Returns true if the character was placed, false if we ran out of room. Definition at line 65 of file charLayout.cxx. References CharPlacement::_height, CharPlacement::_width, _working_buffer_pixels, _working_xsize, _working_ysize, CharPlacement::_x, CharPlacement::_y, find_overlap(), NULL, x, and y.

void CharLayout::reset (  int  working_xsize, int  working_ysize, int  working_buffer_pixels )

Removes all the characters already placed on the layout, and resets the parameters for a new attempt. Definition at line 38 of file charLayout.cxx.
