-
int
get_advance
(void) const¶ Returns the number of pixels by which the pen should be advanced after rendering this glyph.
-
int
get_bottom
(void) const¶ Returns the y coordinate of the bottommost pixel in the glyph.
-
int
get_height
(void) const¶ Returns the height of the glyph in pixels.
-
bool
get_interior_flag
(int x, int y) const¶ Returns true if the indicated pixel represents a pixel in the interior of a hollow font, false otherwise.
-
int
get_left
(void) const¶ Returns the x coordinate of the leftmost pixel in the glyph.
-
int
get_right
(void) const¶ Returns the x coordinate of the rightmost pixel in the glyph.
-
int
get_top
(void) const¶ Returns the y coordinate of the topmost pixel in the glyph.
-
double
get_value
(int x, int y) const¶ Returns the value of the indicated pixel of the glyph. The result is in the range [0, 1], where 0 indicates the pixel is not part of the glyph, and 1 indicates it is. Intermediate values are used to represent antialiasing.
-
int
get_width
(void) const¶ Returns the width of the glyph in pixels.
-
void
place
(PNMImage &dest_image, int xp, int yp, LColor const &fg, LColor const &interior)¶ Copies the glyph to the indicated destination image at the indicated origin. It colors the glyph pixels the indicated foreground color, blends antialiased pixels with the appropriate amount of the foreground color and the existing background color, and leaves other pixels alone.
This flavor of place() also fills in the interior color. This requires that determine_interior was called earlier.
