.. currentmodule:: sdl2.ext
2D drawing routines for software surfaces
=========================================
.. note::
The drawing functions within this module are unoptimised and should not be
considered fast. If you want improved drawing of 2D primitives, including
hardware acceleration, you should use the methods of the
:class:`Renderer` instead.
.. function:: prepare_color(color : object, target : object) -> int
Prepares the passed *color* for a specific *target*. *color* can be any
object type that can be processed by
:func:`convert_to_color()`. *target* can be any
:class:`sdl2.SDL_PixelFormat`, :class:`sdl2.SDL_Surface` or
:class:`SoftwareSprite` instance.
The returned integer will be a color value matching the target's pixel
format.
.. function:: fill(target : object, color : object[, area=None]) -> None
Fills a certain area on the passed *target* with a *color*. If no *area* is
provided, the entire target will be filled with the passed color. If an
iterable item is provided as *area* (such as a list or tuple), it will be
first checked, if the item denotes a single rectangular area
(4 integer values) before assuming it to be a sequence of rectangular areas
to fill with the color.
*target* can be any :class:`sdl2.SDL_Surface` or :class:`SoftwareSprite`
instance.
.. function:: line(target : object, color : object[, width=1]) -> None
Draws one or multiple lines on the passed *target*. *line* can be a
sequence of four integers for a single line in the form ``(x1, y1,
x2, y2)`` or a sequence of a multiple of 4 for drawing multiple lines
at once, e.g. ``(x1, y1, x2, y2, x3, y3, x4, y4, ...)``.
*target* can be any :class:`sdl2.SDL_Surface` or :class:`SoftwareSprite`
instance.
