<p>The PixelArray wraps a Surface and provides direct access to the
|
||
|
|
surface's pixels. A pixel array can be one or two dimensional.
|
||
|
|
A two dimensional array, like its surface, is indexed [column, row].
|
||
|
|
Pixel arrays support slicing, both for returning a subarray or
|
||
|
|
for assignment. A pixel array sliced on a single column or row
|
||
|
|
returns a one dimensional pixel array. Arithmetic and other operations
|
||
|
|
are not supported. A pixel array can be safely assigned to itself.
|
||
|
|
Finally, pixel arrays export an array struct interface, allowing
|
||
|
|
them to interact with <a class="tooltip reference internal" href="pixelcopy.html#module-pygame.pixelcopy" title=""><code class="xref py py-mod docutils literal notranslate"><span class="pre">pygame.pixelcopy</span></code><span class="tooltip-content">pygame module for general pixel array copying</span></a> methods and NumPy
|
||
|
|
arrays.</p>
|
||
|
|
<p>A PixelArray pixel item can be assigned a raw integer values, a

<p>However, only a pixel's integer value is returned. So, to compare a pixel

<p>For PixelArray assignment, if the right hand side array has a row length

of 1, then the column is broadcast over the target array's rows. An

array of height 1 is broadcast over the target's columns, and is equivalent
|

|
|
to assigning a 1D PixelArray.</p>

<p>During its lifetime, the PixelArray locks the surface, thus you explicitly
|
||
|
|
have to close() it once its not used any more and the surface should perform
|
||
|
|
operations in the same scope. It is best to use it as a context manager
|
||
|
|
using the with PixelArray(surf) as pixel_array: style. So it works on pypy too.</p>

<p>A note about PixelArray to PixelArray assignment, for arrays with an
|
||
|
|
item size of 3 (created from 24 bit surfaces) pixel values are translated
|
||
|
|
from the source to the destinations format. The red, green, and blue
|
||
|
|
color elements of each pixel are shifted to match the format of the
|
||
|
|
target surface. For all other pixel sizes no such remapping occurs.
|
||
|
|
This should change in later pygame releases, where format conversions
|
||
|
|
are performed for all pixel sizes. To avoid code breakage when full mapped
|
||
|
|
copying is implemented it is suggested PixelArray to PixelArray copies be
|
||
|
|
only between surfaces of identical format.</p>
