- class SimpleGUICS2Pygame.simpleguics2pygame.image.Image(url: str)[source]
Image similar to SimpleGUI Image of CodeSkulptor.
- __init__(url: str) None [source]
Set an image.
Don’t use directly, use load_image().
- Parameters
url – str
- __weakref__
list of weak references to the object (if defined)
- _dir_search_first = '_img/'
load_image() try first to loading image from this directory, and next if failed, try to loading from URL.
This local directory is relative to the directory of your program.
- _print_stats_cache(text: str = '', short_url: bool = True) None [source]
Print to stderr some statistics of cached Pygame surfaces used by this image.
(Not available in SimpleGUI of CodeSkulptor.)
- Parameters
text – str
short_url – bool
- _pygamesurfaces_cache_default_max_size = 1000
Default maximum number of Pygame surfaces in the self._pygamesurfaces_cached.
- _pygamesurfaces_cached_clear() None [source]
Empty the cache of Pygame surfaces used by this image.
(Not available in SimpleGUI of CodeSkulptor.)
- class SimpleGUICS2Pygame.simpleguics2pygame.image._LocalImage(filename: str)[source]
Child of Image to load local file image.
(Not available in SimpleGUI of CodeSkulptor.)
- SimpleGUICS2Pygame.simpleguics2pygame.image._load_local_image(filename: str) _LocalImage [source]
Create and return an image by loading a file from filename. Not founded file and errors are ignored.
I recommend to use only Internet resources with the load_image() function. Then you can use your program both in standard Python and in CodeSkulptor. (See Tips.html#download-medias .)
But if it is necessary, you can load local image with this “private” function.
Supported formats are the same as the load_image() function.
(Not available in SimpleGUI of CodeSkulptor.)
- Parameters
filename – str (only a valid filename, not URL)
- Returns
_LocalImage
- SimpleGUICS2Pygame.simpleguics2pygame.image.load_image(url: str) SimpleGUICS2Pygame.simpleguics2pygame.image.Image [source]
Create and return an image by loading a file from url. Not founded URL and errors are ignored.
SimpleGUICS2Pygame try first to loading image from Image._dir_search_first local directory (_img/ by default), and next if failed, try to loading from url.
This local directory is relative to the directory of your program.
For example,
load_image('http://commondatastorage.googleapis.com/codeskulptor-assets/lathrop/double_ship.png')
try first to loading from_img/commondatastorage.googleapis.com/codeskulptor_assets/lathrop/double_ship.png
.Supported formats are supported formats by Pygame to load: PNG, JPG, GIF (not animated)… (see https://www.pygame.org/docs/ref/image.html ).
(CodeSkulptor may supported other formats, dependant on browser support.)
I recommend PNG and JPG format.
CodeSkulptor loads images asynchronously (the program continues without waiting for the images to be loaded). To handle this problem, you can use
simplegui_lib_loader.Loader
class.- Parameters
url – str (only a valid URL, not local filename)
- Returns
Image
- SimpleGUICS2Pygame.simpleguics2pygame.image.__all__ = ('Image', '_LocalImage', 'load_image', '_load_local_image')
Built-in immutable sequence.
If no argument is given, the constructor returns an empty tuple. If iterable is specified the tuple is initialized from iterable’s items.
If the argument is a tuple, the return value is the same object.
