sdl2.sdlimage - Python bindings for SDL_image¶
py-sdl2 provides bindings for SDL2_image, a library designed for use with SDL2
that adds support for loading a wide range of different common (and uncommon)
image formats for easy use with SDL2. In addition, SDL2_image includes functions
for saving SDL_Surface
objects to PNG and/or JPEG images.
For a list of supported image formats, see the IMG_LoadTyped_RW()
documentation.

Note
If using an alternative rendering system that doesn’t use SDL surfaces as input (e.g. PyOpenGL), the Pillow imaging library may be a better fit for your project.
Initialization and library information functions¶
-
sdl2.sdlimage.
IMG_Init
(flags)[source]¶ Initializes the SDL_image library.
Calling this function enables support for the JPEG, PNG, TIF, WebP, JPEG XL, and/or AVIF image formats as requested by the init flags. All other image formats can be loaded or used regardless of whether this has been called.
The following init flags are supported:
Format Init flag Since JPEG IMG_INIT_JPG
2.0.0 PNG IMG_INIT_PNG
2.0.0 TIFF IMG_INIT_TIF
2.0.0 WebP IMG_INIT_WEBP
2.0.0 JPEG XL IMG_INIT_JXL
2.6.0 AVIF IMG_INIT_AVIF
2.6.0 This can be called multiple times to enable support for these formats separately, or can initialize multiple formats at once by passing a set of flags as a bitwise OR. You can also call this function with 0 as a flag to check which image libraries have already been loaded, or to test whether a given image format is available on the current system:
# Initialize JPEG and PNG support separately for flag in [IMG_INIT_JPG, IMG_INIT_PNG]: IMG_Init(flag) err = IMG_GetError() # check for any errors loading library if len(err): print(err) # Initialize JPEG and PNG support at the same time flags = IMG_INIT_JPG | IMG_INIT_PNG IMG_Init(flags) if IMG_Init(0) != flags: # verify both libraries loaded properly print(IMG_GetError())
Note
AVIF and JPEG XL support are not included in the official SDL_image binaries, and are likewise not enabled on most Linux distributions.
Parameters: flags (int) – A bitwise OR’d set of the flags of the image formats to load support for. Returns: A bitmask of all the currently initialized image loaders. Return type: int
-
sdl2.sdlimage.
IMG_Quit
()[source]¶ De-initializes the SDL_image library.
Calling this function disables JPEG, PNG, TIF, and WEBP support and frees all associated memory. Once this has been called, you can re-initialize support for those image formats using
IMG_Init()
and the corresponding init flags.You only need to call this function once, no matter how many times
IMG_Init()
was called.
-
sdl2.sdlimage.
IMG_GetError
()¶ Returns the most recently encountered SDL2 error message, if any.
This function is a simple wrapper around
SDL_GetError()
.Retuns: A UTF-8 encoded string describing the most recent SDL2 error. Return type: bytes
Image format-checking functions¶
These functions are used to check whether an SDL file object
(SDL_RWops
) is a valid image file of a given format. Note that
all of these functions will return 0 if SDL2_image was not built with
support for that format, even if it is a valid image of that type, so be
cautious when using these for formats like WEBP, AVIF, JXL, and TIFF, which
are optional when building SDL2_image.

General image loading functions¶
-
sdl2.sdlimage.
IMG_Load
(file)[source]¶ Loads an image file to a new surface.
This can load all supported image files, including TGA as long as the filename ends with “.tga”.
It is best to call this outside of event loops and keep the loaded images around until you are really done with them, as disk speed and image conversion to a surface can be slow.
Once you are done with a loaded image, you can call
SDL_FreeSurface()
on the returned surface pointer to free up the memory associated with it.If the image format supports a transparent pixel, SDL_image will set the colorkey for the surface. You can enable RLE acceleration on the surface afterwards by calling:
SDL_SetColorKey(image, SDL_RLEACCEL, image.contents.format.colorkey)
Note
If the loader for the image’s format requires initialization (e.g. PNG) and it is not already initialized, this function will attempt to load it automatically.
Parameters: file (bytes) – A UTF8-encoded bytestring containing the path to the image file to load. Returns: A pointer to the new surface containing the image, or a null pointer if there was an error. Return type: POINTER( SDL_Surface
)
-
sdl2.sdlimage.
IMG_Load_RW

SDL_RWops
) – The file object from which to load the image. - freesrc (int) – If non-zero, the input file object will be closed and freed after it has been read.
Returns: A pointer to the new surface containing the image, or a null pointer if there was an error.
Return type: POINTER(
SDL_Surface
)- src (
-
sdl2.sdlimage.
IMG_LoadTyped_RW
(src, freesrc, type)[source]¶ Loads an image file from an SDL file object as a specific format.
This function allows you to explicitly specify the format type of the image to load. Here are the different possible image format strings:
Format String Format Type b”TGA” TrueVision Targa b”CUR” Windows Cursor b”ICO” Windows Icon b”BMP” Windows Bitmap b”GIF” Graphics Interchange Format b”JPG” JPEG b”LBM” Interleaved Bitmap b”PCX” IBM PC Paintbrush b”PNG” Portable Network Graphics b”PNM” Portable Anymap b”SVG” Scalable Vector Graphics b”TIF” Tagged Image File Format b”XCF” GIMP native format b”XPM” X11 Pixmap b”XV” XV Thumbnail b”WEBP” WebP b”QOI” Quite OK Image b”JXL” JPEG XL b”AVIF” AV1 Image File Format Note that loading QOI, JXL, and AVIF images requires SDL_image 2.6.0 or newer. See
IMG_Load()
for more information.Parameters: Returns: A pointer to the new surface containing the image, or a null pointer if there was an error.
Return type: POINTER(
SDL_Surface
)
-
sdl2.sdlimage.
IMG_LoadTexture
(renderer, file)[source]¶ Loads an image file to a new texture using a given renderer.
This function can load all supported image files, including TGA as long as the filename ends with “.tga”.
It is best to call this outside of event loops and keep the loaded images around until you are really done with them, as disk speed and image conversion to a texture can be slow.
Once you are done with a loaded image, you can call
SDL_DestroyTexture()
on the returned texture pointer to free up the memory associated with it.Note
If the image loader for the format of the given image requires initialization (e.g. PNG) and it is not already initialized, this function will attempt to load it automatically.
Parameters: - renderer (
SDL_Renderer
) – The SDL rendering context with which to create the texture. - file (bytes) – A UTF8-encoded bytestring containing the path to the image file to load.
Returns: A pointer to the new texture containing the image, or a null pointer if there was an error.

Animation objects and functions¶
-
class
sdl2.sdlimage.
IMG_Animation
[source]¶ A structure containing the frame data for an animation.
When working with this data structure in Python, you need to be careful not to access an out-of-range frame or delay number to avoid illegal memory access problems. To convert the animation data to a more Pythonic format, you can do something similar to the example below:
# Load animation and verify it loaded correctly anim = sdlimage.IMG_LoadAnimation("test.gif").contents if not anim: err = sdlimage.IMG_GetError() raise RuntimeError(err.encode("utf-8")) # Load frames/delays from the IMG_Animation structure to lists frames = [] delays = [] for frame in range(anim.count): frames.append(anim.frames[frame].contents) delays.append(anim.delays[frame])
Note that even if you copy the frame surfaces into a Python list, the pixel data will still be stored within the animation object. As such, you cannot call
IMG_FreeAnimation()
on an object until you are fully done with its data.-
frames
¶ An array of pointers (of length
count
) to the SDL surfaces for the frames of the animation.Type: POINTER(POINTER( SDL_Surface
))
