<p>The image module contains functions for loading and saving pictures, as well as
|
||
|
|
transferring Surfaces to formats usable by other packages.</p>
|
||
|
|
<p>Note that there is no Image class; an image is loaded as a Surface object. The
|
||
|
|
Surface class allows manipulation (drawing lines, setting pixels, capturing
|
||
|
|
regions, etc.).</p>
|
||
|
|
<p>In the vast majority of installations, pygame is built to support extended
|
||
|
|
formats, using the SDL_Image library behind the scenes. However, some
|
||
|
|
installations may only support uncompressed <code class="docutils literal notranslate"><span class="pre">BMP</span></code> images. With full image
|
||
|
|
support, the <a class="tooltip reference internal" href="#pygame.image.load" title=""><code class="xref py py-func docutils literal notranslate"><span class="pre">pygame.image.load()</span></code><span class="tooltip-content">load new image from a file (or file-like object)</span></a> function can load the following

<p>Load an image from a file source. You can pass either a filename, a Python
|
||
|
|
file-like object, or a pathlib.Path.</p>
|
||
|
|
<p>Pygame will automatically determine the image type (e.g., <code class="docutils literal notranslate"><span class="pre">GIF</span></code> or bitmap)
|
||
|
|
and create a new Surface object from the data. In some cases it will need to
|
||
|
|
know the file extension (e.g., <code class="docutils literal notranslate"><span class="pre">GIF</span></code> images should end in ".gif"). If you
|
||
|
|
pass a raw file-like object, you may also want to pass the original filename
|
||
|
|
as the namehint argument.</p>
|
||
|
|
<p>The returned Surface will contain the same color format, colorkey and alpha
|
||
|
|
transparency as the file it came from. You will often want to call
|
||
|
|
<a class="tooltip reference internal" href="surface.html#pygame.Surface.convert" title=""><code class="xref py py-func docutils literal notranslate"><span class="pre">pygame.Surface.convert()</span></code><span class="tooltip-content">change the pixel format of an image</span></a> with no arguments, to create a copy that
|
||
|
|
will draw more quickly on the screen.</p>
|
||
|
|
<p>For alpha transparency, like in .png images, use the
|
||
|
|
<a class="tooltip reference internal" href="surface.html#pygame.Surface.convert_alpha" title=""><code class="xref py py-func docutils literal notranslate"><span class="pre">pygame.Surface.convert_alpha()</span></code><span class="tooltip-content">change the pixel format of an image including per pixel alphas</span></a> method after loading so that the
|
||
|
|
image has per pixel transparency.</p>
|
||
|
|
<p>Pygame may not always be built to support all image formats. At minimum it
|
||
|
|
will support uncompressed <code class="docutils literal notranslate"><span class="pre">BMP</span></code>. If <a class="tooltip reference internal" href="#pygame.image.get_extended" title=""><code class="xref py py-func docutils literal notranslate"><span class="pre">pygame.image.get_extended()</span></code><span class="tooltip-content">test if extended image formats can be loaded</span></a>
|
||
|
|
returns <code class="docutils literal notranslate"><span class="pre">True</span></code>, you should be able to load most images (including PNG, JPG
|
||
|
|
and GIF).</p>
|
||
|

<p>You should use <code class="xref py py-func docutils literal notranslate"><span class="pre">os.path.join()</span></code> for compatibility.</p>
