.TH SDL_SetRenderLogicalPresentation 3 "SDL 3.1.0" "SDL" "SDL3 FUNCTIONS"
.SH NAME
SDL_SetRenderLogicalPresentation \- Set a device independent resolution and presentation mode for rendering\[char46]
.SH SYNOPSIS
.nf
.B #include \(dqSDL3/SDL.h\(dq
.PP
.BI "int SDL_SetRenderLogicalPresentation(SDL_Renderer *renderer, int w, int h, SDL_RendererLogicalPresentation mode, SDL_ScaleMode scale_mode);
.fi
.SH DESCRIPTION
This function sets the width and height of the logical rendering output\[char46] A
render target is created at the specified size and used for rendering and
then copied to the output during presentation\[char46]

You can disable logical coordinates by setting the mode to

.BR SDL_LOGICAL_PRESENTATION_DISABLED
, and
in that case you get the full pixel resolution of the output window\[char46]

You can convert coordinates in an event into rendering coordinates using

.BR SDL_ConvertEventToRenderCoordinates
()\[char46]

.SH FUNCTION PARAMETERS
.TP
.I renderer
the rendering context
.TP
.I w
the width of the logical resolution
.TP
.I h
the height of the logical resolution
.TP
.I mode
the presentation mode used
.TP
.I scale_mode
the scale mode used
.SH RETURN VALUE
Returns 0 on success or a negative error code on failure; call

.BR SDL_GetError
() for more information\[char46]

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