.TH IMG_LoadTyped_IO 3 "SDL_image 3.0.0" "SDL_image" "SDL_image3 FUNCTIONS"
.SH NAME
IMG_LoadTyped_IO \- Load an image from an SDL data source into a software surface\[char46]
.SH SYNOPSIS
.nf
.B #include \(dqSDL3_image/SDL_image.h\(dq
.PP
.BI "SDL_Surface * IMG_LoadTyped_IO(SDL_IOStream *src, SDL_bool closeio, const char *type);
.fi
.SH DESCRIPTION
An SDL_Surface is a buffer of pixels in memory accessible by the CPU\[char46] Use
this if you plan to hand the data to something else or manipulate it
further in code\[char46]

There are no guarantees about what format the new SDL_Surface data will be;
in many cases, SDL_image will attempt to supply a surface that exactly
matches the provided image, but in others it might have to convert (either
because the image is in a format that SDL doesn't directly support or
because it's compressed data that could reasonably uncompress to various
formats and SDL_image had to pick one)\[char46] You can inspect an SDL_Surface for
its specifics, and use SDL_ConvertSurface to then migrate to any supported
format\[char46]

If the image format supports a transparent pixel, SDL will set the colorkey
for the surface\[char46] You can enable RLE acceleration on the surface afterwards
by calling: SDL_SetSurfaceColorKey(image, SDL_RLEACCEL,
image->format->colorkey);

If
.BR closeio
is SDL_TRUE,
.BR src
will be closed before returning, whether
this function succeeds or not\[char46] SDL_image reads everything it needs from
.BR src
during this call in any case\[char46]

Even though this function accepts a file type, SDL_image may still try
other decoders that are capable of detecting file type from the contents of
the image data, but may rely on the caller-provided type string for formats
that it cannot autodetect\[char46] If
.BR type
is NULL, SDL_image will rely solely on
its ability to guess the format\[char46]

There is a separate function to read files from disk without having to deal
with SDL_IOStream:
.BR IMG_Load("filename\[char46]jpg")
will call this function and
manage those details for you, determining the file type from the filename's
extension\[char46]

There is also 
.BR IMG_Load_IO
(), which is equivalent to this
function except that it will rely on SDL_image to determine what type of
data it is loading, much like passing a NULL for type\[char46]

If you are using SDL's 2D rendering API, there is an equivalent call to
load images directly into an SDL_Texture for use by the GPU without using a
software surface: call 
.BR IMG_LoadTextureTyped_IO
()
instead\[char46]

When done with the returned surface, the app should dispose of it with a
call to SDL_DestroySurface()\[char46]

.SH FUNCTION PARAMETERS
.TP
.I src
an SDL_IOStream that data will be read from\[char46]
.TP
.I closeio
SDL_TRUE to close/free the SDL_IOStream before returning, SDL_FALSE to leave it open\[char46]
.TP
.I type
a filename extension that represent this data ("BMP", "GIF", "PNG", etc)\[char46]
.SH RETURN VALUE
Returns a new SDL surface, or NULL on error\[char46]

.SH AVAILABILITY
This function is available since SDL_image 3\[char46]0\[char46]0\[char46]
