Return the string dimension in pixels.
The height and width are returned in a single Dimension value. TINYFONT, BIGFONT modifiers are only supported as the first character of the string. The returned dimensions are therefore a rough estimation correct for all the current strings but not every possible combination

void GfxFillPolygon | ( | const std::vector< Point > & | shape, |
int | colour, | ||
FillRectMode | mode | ||
) |
Fill a polygon with colour.
The odd-even winding rule is used, i.e. self-intersecting polygons will have holes in them. Left and top edges are inclusive, right and bottom edges are exclusive.
shape | List of points on the polygon. |
colour | An 8 bit palette index (FILLRECT_OPAQUE and FILLRECT_CHECKER) or a recolour spritenumber (FILLRECT_RECOLOUR). |
mode | FILLRECT_OPAQUE: Fill the polygon with the specified colour. FILLRECT_CHECKER: Fill every other pixel with the specified colour, in a checkerboard pattern. FILLRECT_RECOLOUR: Apply a recolour sprite to every pixel in the polygon. |
