Surface#rotozoom( angle, zoom, smooth )Returns a new surface that is rotated angle degrees and zoomed zoom times (fractions are OK). This method returns a 32 bit surface. Exception: for now it returns an 8 bit surface when fed an 8 bit surface. If smooth is true and the surface is not 8 bits, bilinear interpolation will be applied, resulting in a smoother image.
Surface#zoom( zoom_horizontal, zoom_vertical, smooth )Returns a new surface that is zoomed. 1.0 doesn't zoom, bigger than 1.0 zooms in, smaller than 1.0 zooms out. This method returns a 32 bit surface. Exception: for now it returns an 8 bit surface when fed an 8 bit surface. If smooth is true and the surface is not 8 bits, bilinear interpolation will be applied, resulting in a smoother image. (The last two methods are from Andreas Schiffler's SDL_rotozoom, aschiffler@home.com)
For these methods, "antialiased" means that drawing is done with many shades of the requested color to simulate
Surface#plot( coordinate, color )Surface#[ x, y ]= colorThese methods access single pixels on a surface. plot or []= set a pixel to color at coordinate. get or [] get the color of a pixel. These methods require the surface to be locked if neccesary. []= and [] are the only methods in RUDL that take a seperate x and y coordinate.
Surface#horizontal_line( coord, endx, color )Surface#vertical_line( coord, endy, color )Surface#rectangle( rect, color )Surface#filled_rectangle( rect, color )Surface#line( coord1, coord2, color )Surface#antialiased_line( coord1, coord2, color )Surface#circle( coord, radius, color )Surface#filled_circle( coord, radius, color )Surface#antialiased_circle( coord, radius, color )Surface#filled_pie( coord, radius, start, end, color )Surface#ellipse( coord, radius_x, radius_y, color )Surface#antialiased_ellipse( coord, radius_x, radius_y, color )Surface#filled_ellipse( coord, radius_x, radius_y, color )These methods are thought to be self-explanatory. Filled_rectangle is a lot like fill. Fill comes from SDL, filled_rectangle from SDL_gfx, choose whichever you like best.
Surface#polygon( coord_list, color )Surface#filled_polygon( coord_list, color )Surface#antialiased_polygon( coord_list, color)The polygon methods take an array of [x,y], like [[10,10],[40,60],[16,66]].
Surface#print( coord, text, color )Puts text on the surface in a monospaced 8x8 standard old ASCII font.
