Variants

JCS_UNKNOWN

error/unspecified

JCS_GRAYSCALE

monochrome

JCS_RGB

red/green/blue as specified by the RGB_RED, RGB_GREEN, RGB_BLUE, and RGB_PIXELSIZE macros

JCS_YCbCr

Y/Cb/Cr (also known as YUV)

JCS_CMYK

C/M/Y/K

JCS_YCCK

Y/Cb/Cr/K

JCS_EXT_RGB

red/green/blue

JCS_EXT_RGBX

red/green/blue/x When out_color_space it set to JCS_EXT_RGBX, JCS_EXT_BGRX, JCS_EXT_XBGR, or JCS_EXT_XRGB during decompression, the X byte is undefined, and in order to ensure the best performance, libjpeg-turbo can set that byte to whatever value it wishes.

JCS_EXT_BGR

blue/green/red

JCS_EXT_BGRX

blue/green/red/x

JCS_EXT_XBGR

x/blue/green/red

JCS_EXT_XRGB

x/red/green/blue

JCS_EXT_RGBA

Use the following colorspace constants to ensure that the X byte is set to 0xFF, so that it can be interpreted as an opaque alpha channel.

red/green/blue/alpha

JCS_EXT_BGRA

blue/green/red/alpha

JCS_EXT_ABGR

alpha/blue/green/red

JCS_EXT_ARGB

alpha/red/green/blue

JCS_RGB565

5-bit red/6-bit green/5-bit blue

Trait Implementations

impl Copy for J_COLOR_SPACE

impl Debug for J_COLOR_SPACE

fn fmt(&self, f: &mut Formatter) -> Result<(), Error>
