Detailed Description

Largely these facilities deal with pixel format: what does this set of bits represent?

If you mostly want to think of a pixel as some combination of red, green, blue, and maybe alpha intensities, this is all pretty straightforward, and in many cases, is enough information to build a perfectly fine game.

However, the actual definition of a pixel is more complex than that:

Pixels are a representation of a color in a particular color space.

The first characteristic of a color space is the color type. SDL understands two different color types, RGB and YCbCr, or in SDL also referred to as YUV.

RGB colors consist of red, green, and blue channels of color that are added together to represent the colors we see on the screen.

https://en.wikipedia.org/wiki/RGB_color_model

YCbCr colors represent colors as a Y luma brightness component and red and blue chroma color offsets. This color representation takes advantage of the fact that the human eye is more sensitive to brightness than the color in an image. The Cb and Cr components are often compressed and have lower resolution than the luma component.

https://en.wikipedia.org/wiki/YCbCr

When the color information in YCbCr is compressed, the Y pixels are left at full resolution and each Cr and Cb pixel represents an average of the color information in a block of Y pixels. The chroma location determines where in that block of pixels the color information is coming from.

The color range defines how much of the pixel to use when converting a pixel into a color on the display. When the full color range is used, the entire numeric range of the pixel bits is significant. When narrow color range is used, for historical reasons, the pixel uses only a portion of the numeric range to represent colors.

The color primaries and white point are a definition of the colors in the color space relative to the standard XYZ color space.

https://en.wikipedia.org/wiki/CIE_1931_color_space

The transfer characteristic, or opto-electrical transfer function (OETF), is the way a color is converted from mathematically linear space into a non-linear output signals.

https://en.wikipedia.org/wiki/Rec._709#Transfer_characteristics

The matrix coefficients are used to convert between YCbCr and RGB colors.

◆ SDL_PIXELFLAG

#define SDL_PIXELFLAG ( format ) (((format) >> 28) & 0x0F)

This macro is generally not needed directly by an app, which should use specific tests, like SDL_ISPIXELFORMAT_FOURCC, instead.

Parameters

format an PixelFormat to check.

Returns: the flags of format.

Thread safety:: It is safe to call this macro from any thread.

Since: This macro is available since SDL 3.2.0.

Function Documentation

◆ GetRGB()

void SDL::GetRGB	(	Uint32	pixel,
		const PixelFormatDetails &	format,
		const PaletteBase &	palette,
		Uint8 *	r,
		Uint8 *	g,
		Uint8 *	b
	)

inline

This function uses the entire 8-bit [0..255] range when converting color components from pixel formats with less than 8-bits per RGB component (e.g., a completely white pixel in 16-bit RGB565 format would return [0xff, 0xff, 0xff] not [0xf8, 0xfc, 0xf8]).

Parameters

pixel	a pixel value.
format	a reference to PixelFormatDetails describing the pixel format.
palette	an optional palette for indexed formats, may be nullptr.
r	a pointer filled in with the red component, may be nullptr.
g	a pointer filled in with the green component, may be nullptr.
b	a pointer filled in with the blue component, may be nullptr.

Thread safety:: It is safe to call this function from any thread, as long as the palette is not modified.

Since: This function is available since SDL 3.2.0.

◆ GetRGBA()

void SDL::GetRGBA	(	Uint32	pixel,
		const PixelFormatDetails &	format,
		const PaletteBase &	palette,
		Uint8 *	r,
		Uint8 *	g,
		Uint8 *	b,
		Uint8 *	a
	)

inline

This function uses the entire 8-bit [0..255] range when converting color components from pixel formats with less than 8-bits per RGB component (e.g., a completely white pixel in 16-bit RGB565 format would return [0xff, 0xff, 0xff] not [0xf8, 0xfc, 0xf8]).

If the surface has no alpha component, the alpha will be returned as 0xff (100% opaque).

Parameters

pixel	a pixel value.
format	a reference to PixelFormatDetails describing the pixel format.
palette	an optional palette for indexed formats, may be nullptr.
r	a pointer filled in with the red component, may be nullptr.
g	a pointer filled in with the green component, may be nullptr.
b	a pointer filled in with the blue component, may be nullptr.
a	a pointer filled in with the alpha component, may be nullptr.

Thread safety:: It is safe to call this function from any thread, as long as the palette is not modified.

Since: This function is available since SDL 3.2.0.

◆ MapRGB()

Uint32 SDL::MapRGB	(	const PixelFormatDetails &	format,
		const PaletteBase &	palette,
		Uint8	r,
		Uint8	g,
		Uint8	b
	)

inline

This function maps the RGB color value to the specified pixel format and returns the pixel value best approximating the given RGB color value for the given pixel format.

If the format has a palette (8-bit) the index of the closest matching color in the palette will be returned.

If the specified pixel format has an alpha component it will be returned as all 1 bits (fully opaque).

If the pixel format bpp (color depth) is less than 32-bpp then the unused upper bits of the return value can safely be ignored (e.g., with a 16-bpp format the return value can be assigned to a Uint16, and similarly a Uint8 for an 8-bpp format).

Parameters

format	a reference to PixelFormatDetails describing the pixel format.
palette	an optional palette for indexed formats, may be nullptr.
r	the red component of the pixel in the range 0-255.
g	the green component of the pixel in the range 0-255.
b	the blue component of the pixel in the range 0-255.

Returns: a pixel value.

Thread safety:: It is safe to call this function from any thread, as long as the palette is not modified.

Since: This function is available since SDL 3.2.0.

◆ MapRGBA()

Uint32 SDL::MapRGBA	(	const PixelFormatDetails &	format,
		const PaletteBase &	palette,
		Uint8	r,
		Uint8	g,
		Uint8	b,
		Uint8	a
	)

inline

This function maps the RGBA color value to the specified pixel format and returns the pixel value best approximating the given RGBA color value for the given pixel format.

If the specified pixel format has no alpha component the alpha value will be ignored (as it will be in formats with a palette).

If the format has a palette (8-bit) the index of the closest matching color in the palette will be returned.

If the pixel format bpp (color depth) is less than 32-bpp then the unused upper bits of the return value can safely be ignored (e.g., with a 16-bpp format the return value can be assigned to a Uint16, and similarly a Uint8 for an 8-bpp format).

Parameters

format	a reference to PixelFormatDetails describing the pixel format.
palette	an optional palette for indexed formats, may be nullptr.
r	the red component of the pixel in the range 0-255.
g	the green component of the pixel in the range 0-255.
b	the blue component of the pixel in the range 0-255.
a	the alpha component of the pixel in the range 0-255.

Returns: a pixel value.

Thread safety:: It is safe to call this function from any thread, as long as the palette is not modified.

Since: This function is available since SDL 3.2.0.
