.TH SDL_CreateSurfaceFrom 3 "SDL 3.1.0" "SDL" "SDL3 FUNCTIONS"
.SH NAME
SDL_CreateSurfaceFrom \- Allocate a new RGB surface with a specific pixel format and existing pixel data\[char46]
.SH SYNOPSIS
.nf
.B #include \(dqSDL3/SDL.h\(dq
.PP
.BI "SDL_Surface* SDL_CreateSurfaceFrom(void *pixels, int width, int height, int pitch, SDL_PixelFormatEnum format);
.fi
.SH DESCRIPTION
No copy is made of the pixel data\[char46] Pixel data is not managed automatically;
you must free the surface before you free the pixel data\[char46]

Pitch is the offset in bytes from one row of pixels to the next, e\[char46]g\[char46]
.BR width*4
for 
.BR
.BR SDL_PIXELFORMAT_RGBA8888
\[char46]

You may pass NULL for pixels and 0 for pitch to create a surface that you
will fill in with valid values later\[char46]

.SH FUNCTION PARAMETERS
.TP
.I pixels
a pointer to existing pixel data
.TP
.I width
the width of the surface
.TP
.I height
the height of the surface
.TP
.I pitch
the number of bytes between each row, including padding
.TP
.I format
the 
.BR SDL_PixelFormatEnum
 for the new surface's pixel format\[char46]
.SH RETURN VALUE
Returns the new 
.BR SDL_Surface
 structure that is created or
NULL if it fails; call 
.BR SDL_GetError
() for more information\[char46]

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