<p>Draw several simple shapes to a surface. These functions will work for
|
|
rendering to any format of surface.</p>
|
|
<p>Most of the functions take a width argument to represent the size of stroke
|
|
(thickness) around the edge of the shape. If a width of 0 is passed the shape
|
|
will be filled (solid).</p>
|
|
<p>All the drawing functions respect the clip area for the surface and will be
|
|
constrained to that area. The functions return a rectangle representing the
|
|
bounding area of changed pixels. This bounding rectangle is the 'minimum'
|
|
bounding box that encloses the affected area.</p>
|
|
<p>All the drawing functions accept a color argument that can be one of the
|
|
following formats:</p>
|
|
<blockquote>
|
|
<div><ul class="simple">
|
|
<li><p>a <a class="tooltip reference internal" href="color.html#pygame.Color" title=""><code class="xref py py-mod docutils literal notranslate"><span class="pre">pygame.Color</span></code><span class="tooltip-content">pygame object for color representations</span></a> object</p></li>
|
|
<li><p>an <code class="docutils literal notranslate"><span class="pre">(RGB)</span></code> triplet (tuple/list)</p></li>
|
|
<li><p>an <code class="docutils literal notranslate"><span class="pre">(RGBA)</span></code> quadruplet (tuple/list)</p></li>
|
|
<li><p>an integer value that has been mapped to the surface's pixel format
|
|
(see <a class="tooltip reference internal" href="surface.html#pygame.Surface.map_rgb" title=""><code class="xref py py-func docutils literal notranslate"><span class="pre">pygame.Surface.map_rgb()</span></code><span class="tooltip-content">convert a color into a mapped color value</span></a> and <a class="tooltip reference internal" href="surface.html#pygame.Surface.unmap_rgb" title=""><code class="xref py py-func docutils literal notranslate"><span class="pre">pygame.Surface.unmap_rgb()</span></code><span class="tooltip-content">convert a mapped integer color value into a Color</span></a>)</p></li>
|
|
</ul>
|
|
</div></blockquote>
|
|
<p>A color's alpha value will be written directly into the surface (if the
|
|
surface contains pixel alphas), but the draw function will not draw
|
|
transparently.</p>
|
|
<p>These functions temporarily lock the surface they are operating on. Many
|
|
sequential drawing calls can be sped up by locking and unlocking the surface
|
|
object around the draw calls (see <a class="tooltip reference internal" href="surface.html#pygame.Surface.lock" title=""><code class="xref py py-func docutils literal notranslate"><span class="pre">pygame.Surface.lock()</span></code><span class="tooltip-content">lock the Surface memory for pixel access</span></a> and
