pygame.image
- pygame module for image transfer— load new image from a file (or file-like object) — save an image to file (or file-like object) — get version number of the SDL_Image library being used — test if extended image formats can be loaded — transfer image to byte buffer — transfer image to byte buffer — create new Surface from a byte buffer — create new Surface from a byte buffer — create a new Surface that shares data inside a bytes buffer — load new BMP image from a file (or file-like object) — load an image from a file (or file-like object) — save a png/jpg image to file (or file-like object) The image module contains functions for loading and saving pictures, as well as transferring Surfaces to formats usable by other packages. 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.). 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 BMPimages. With full image support, thepygame.image.load()load new image from a file (or file-like object) function can load the following formats.- BMP
- GIF(non-animated)
- JPEG
- LBM(and- PBM,- PGM,- PPM)
- PCX
- PNG
- PNM
- SVG(limited support, using Nano SVG)
- TGA(uncompressed)
- TIFF
- WEBP
- XPM
 New in pygame 2.0: Loading SVG, WebP, PNM Saving images only supports a limited set of formats. You can save to the following formats. - BMP
- JPEG
- PNG
- TGA
 JPEGandJPG, as well asTIFandTIFFrefer to the same file formatNew in pygame 1.8: Saving PNG and JPEG files. - pygame.image.load()¶
- load new image from a file (or file-like object)load(filename) -> Surfaceload(fileobj, namehint="") -> SurfaceLoad an image from a file source. You can pass either a filename, a Python file-like object, or a pathlib.Path. Pygame will automatically determine the image type (e.g., GIFor bitmap) and create a new Surface object from the data. In some cases it will need to know the file extension (e.g.,GIFimages 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.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 pygame.Surface.convert()change the pixel format of an image with no arguments, to create a copy that will draw more quickly on the screen.For alpha transparency, like in .png images, use the pygame.Surface.convert_alpha()change the pixel format of an image including per pixel alphas method after loading so that the image has per pixel transparency.Pygame may not always be built to support all image formats. At minimum it will support uncompressed BMP. Ifpygame.image.get_extended()test if extended image formats can be loaded returnsTrue, you should be able to load most images (including PNG, JPG and GIF).You should use os.path.join()for compatibility.eg. asurf = pygame.image.load(os.path.join('data', 'bla.png')) 
 - pygame.image.save()¶
- save an image to file (or file-like object)save(Surface, filename) -> Nonesave(Surface, fileobj, namehint="") -> NoneThis will save your Surface as either a BMP,TGA,PNG, orJPEGimage. If the filename extension is unrecognized it will default toTGA. BothTGA, andBMPfile formats create uncompressed files. You can pass a filename, a pathlib.Path or a Python file-like object. For file-like object, the image is saved toTGAformat unless a namehint with a recognizable extension is passed in.Note When saving to a file-like object, it seems that for most formats, the object needs to be flushed after saving to it to make loading from it possible. Changed in pygame 1.8: Saving PNG and JPEG files. Changed in pygame 2.0.0: The namehintparameter was added to make it possible to save other formats thanTGAto a file-like object. Saving to a file-like object with JPEG is possible.
 - pygame.image.get_sdl_image_version()¶
- get version number of the SDL_Image library being usedget_sdl_image_version(linked=True) -> Noneget_sdl_image_version(linked=True) -> (major, minor, patch)If pygame is built with extended image formats, then this function will return the SDL_Image library's version number as a tuple of 3 integers (major, minor, patch). If not, then it will returnNone.linked=Trueis the default behavior and the function will return the version of the library that Pygame is linked against, whilelinked=Falsewill return the version of the library that Pygame is compiled against.New in pygame 2.0.0. Changed in pygame 2.2.0: linkedkeyword argument added and default behavior changed from returning compiled version to returning linked version
 - pygame.image.get_extended()¶
- test if extended image formats can be loadedget_extended() -> boolIf pygame is built with extended image formats this function will return True. It is still not possible to determine which formats will be available, but generally you will be able to load them all. 
 - pygame.image.tostring()¶
- transfer image to byte buffertostring(Surface, format, flipped=False) -> bytesCreates a string of bytes that can be transferred with the fromstringorfrombytesmethods in other Python imaging packages. Some Python image packages prefer their images in bottom-to-top format (PyOpenGL for example). If you passTruefor the flipped argument, the byte buffer will be vertically flipped.The format argument is a string of one of the following values. Note that only 8-bit Surfaces can use the "P" format. The other formats will work for any Surface. Also note that other Python image packages support more formats than pygame. - P, 8-bit palettized Surfaces
- RGB, 24-bit image
- RGBX, 32-bit image with unused space
- RGBA, 32-bit image with an alpha channel
- ARGB, 32-bit image with alpha channel first
- BGRA, 32-bit image with alpha channel, red and blue channels swapped
- RGBA_PREMULT, 32-bit image with colors scaled by alpha channel
- ARGB_PREMULT, 32-bit image with colors scaled by alpha channel, alpha channel first
 Note it is preferred to use tobytes()as of pygame 2.1.3New in pygame 2.1.3: BGRA format 
 - pygame.image.tobytes()¶
- transfer image to byte buffertobytes(Surface, format, flipped=False) -> bytesCreates a string of bytes that can be transferred with the fromstringorfrombytesmethods in other Python imaging packages. Some Python image packages prefer their images in bottom-to-top format (PyOpenGL for example). If you passTruefor the flipped argument, the byte buffer will be vertically flipped.The format argument is a string of one of the following values. Note that only 8-bit Surfaces can use the "P" format. The other formats will work for any Surface. Also note that other Python image packages support more formats than pygame. - P, 8-bit palettized Surfaces

- ARGB, 32-bit image with alpha channel first
- BGRA, 32-bit image with alpha channel, red and blue channels swapped
- RGBA_PREMULT, 32-bit image with colors scaled by alpha channel
- ARGB_PREMULT, 32-bit image with colors scaled by alpha channel, alpha channel first
 Note this function is an alias for tostring(). The use of this function is recommended overtostring()as of pygame 2.1.3. This function was introduced so it matches nicely with other libraries (PIL, numpy, etc), and with people's expectations.New in pygame 2.1.3. 
 - pygame.image.fromstring()¶
- create new Surface from a byte bufferfromstring(bytes, size, format, flipped=False) -> SurfaceThis function takes arguments similar to pygame.image.tostring()transfer image to byte buffer. The size argument is a pair of numbers representing the width and height. Once the new Surface is created it is independent from the memory of the bytes passed in.The bytes and format passed must compute to the exact size of image specified. Otherwise a ValueErrorwill be raised.See the pygame.image.frombuffer()create a new Surface that shares data inside a bytes buffer method for a potentially faster way to transfer images into pygame.Note it is preferred to use frombytes()as of pygame 2.1.3

 - pygame.image.frombuffer()¶
- create a new Surface that shares data inside a bytes bufferfrombuffer(buffer, size, format) -> SurfaceCreate a new Surface that shares pixel data directly from a buffer. This buffer can be bytes, a bytearray, a memoryview, a pygame.BufferProxypygame object to export a surface buffer through an array protocol, or any object that supports the buffer protocol. This method takes similar arguments topygame.image.fromstring()create new Surface from a byte buffer, but is unable to vertically flip the source data.This will run much faster than pygame.image.fromstring()create new Surface from a byte buffer, since no pixel data must be allocated and copied.It accepts the following 'format' arguments: - P, 8-bit palettized Surfaces
- RGB, 24-bit image
- BGR, 24-bit image, red and blue channels swapped.
- RGBX, 32-bit image with unused space
- RGBA, 32-bit image with an alpha channel
- ARGB, 32-bit image with alpha channel first
- BGRA, 32-bit image with alpha channel, red and blue channels swapped
 New in pygame 2.1.3: BGRA format 
 - pygame.image.load_basic()¶
- load new BMP image from a file (or file-like object)load_basic(file) -> SurfaceLoad an image from a file source. You can pass either a filename or a Python file-like object, or a pathlib.Path. This function only supports loading "basic" image format, ie BMPformat. This function is always available, no matter how pygame was built.
 - pygame.image.load_extended()¶
- load an image from a file (or file-like object)load_extended(filename) -> Surfaceload_extended(fileobj, namehint="") -> SurfaceThis function is similar to pygame.image.load()load new image from a file (or file-like object), except that this function can only be used if pygame was built with extended image format support.Changed in pygame 2.0.1: This function is always available, but raises an NotImplementedErrorif extended image formats are not supported. Previously, this function may or may not be available, depending on the state of extended image format support.
 - pygame.image.save_extended()¶
- save a png/jpg image to file (or file-like object)save_extended(Surface, filename) -> Nonesave_extended(Surface, fileobj, namehint="") -> NoneThis will save your Surface as either a PNGorJPEGimage.In case the image is being saved to a file-like object, this function uses the namehint argument to determine the format of the file being saved. Saves to JPEGin case the namehint was not specified while saving to a file-like object.Changed in pygame 2.0.1: This function is always available, but raises an NotImplementedErrorif extended image formats are not supported. Previously, this function may or may not be available, depending on the state of extended image format support.
