Member Function Documentation

void clear ( void   )

The frame buffer is cleared by 0.

Parameters:
none.
Returns:
none.

Definition at line 49 of file tinydraw.cpp.

void drawChar ( TD_POINT_t *  pnt,
int  c,
TD_COLOR_PAIR_t *  col,
const struct font_desc *  fontdesc 
)

It draws in the character.

Parameters:
pnt[in] point of draw (upper left corner of font)
c[in] character code(only use ASCII-CODE now)
col[in] Color-code.
fontdesc[in] font-descriptor.
Returns:
none.

Definition at line 63 of file tinydraw.cpp.

void drawLine ( TD_POINT_t *  p1,
TD_POINT_t *  p2,
TD_COLOR_PAIR_t *  col 
)

It draws in the line.

Parameters:
p1[in] point of start.
p2[in] point of end.
col[in] Color-code (now only use 'fore').
Returns:
none.

Definition at line 113 of file tinydraw.cpp.

void drawPoint ( TD_XY_t  x,
TD_XY_t  y,
TD_COLOR_t  fcol 
)

The dot is drawn in specified coordinates by the specified color code.

Parameters:
x[in] X coordinates
y[in] Y coordinates
fcol[in] Color-code (0 or 1 or COL_TRANS).
Returns:
none.

Definition at line 29 of file tinydraw.cpp.

void drawStr ( TD_POINT_t *  pnt,
char *  str,
TD_COLOR_PAIR_t *  col,
const struct font_desc *  fontdesc 
)

It draws in the string.

Parameters:
pnt[in] point of draw (upper left corner of font)
str[in] string (only use ASCII-CODE now)
col[in] Color-code.
fontdesc[in] font-descriptor.
Returns:
none.

Definition at line 87 of file tinydraw.cpp.

char * getCharImage ( int  c,
const struct font_desc *  fontdesc 
)

Get the bit map image of the font.

Parameters:
c[in] character code(only use ASCII-CODE now)
fontdesc[in] font-descriptor.
Returns:
pointer for bit map image.

Definition at line 56 of file tinydraw.cpp.

TD_COLOR_t * getVRAMPtr ( void   )

Get the top of framebuffer pointer.

Parameters:
none.
Returns:
pointer for top of framebuffer.
