  - PF_CMYK
```
public static final int PF_CMYK
```
    CMYK pixel format. Unlike RGB, which is an additive color model used primarily for display, CMYK (Cyan/Magenta/Yellow/Key) is a subtractive color model used primarily for printing. In the CMYK color model, the value of each color component typically corresponds to an amount of cyan, magenta, yellow, or black ink that is applied to a white background. In order to convert between CMYK and RGB, it is necessary to use a color management system (CMS.) A CMS will attempt to map colors within the printer's gamut to perceptually similar colors in the display's gamut and vice versa, but the mapping is typically not 1:1 or reversible, nor can it be defined with a simple formula. Thus, such a conversion is out of scope for a codec library. However, the TurboJPEG API allows for compressing CMYK pixels into a YCCK JPEG image (see CS_YCCK) and decompressing YCCK JPEG images into CMYK pixels.

    Constant Field Values
  - NUMCS

```
    The number of JPEG colorspaces
    
    See Also:
    Constant Field Values
  - CS_RGB
```
public static final int CS_RGB
```
    RGB colorspace. When compressing the JPEG image, the R, G, and B components in the source image are reordered into image planes, but no colorspace conversion or subsampling is performed. RGB JPEG images can be decompressed to any of the extended RGB pixel formats or grayscale, but they cannot be decompressed to YUV images.
    
    See Also:
    Constant Field Values
  - CS_YCbCr
```
public static final int CS_YCbCr
```
    YCbCr colorspace. YCbCr is not an absolute colorspace but rather a mathematical transformation of RGB designed solely for storage and transmission. YCbCr images must be converted to RGB before they can actually be displayed. In the YCbCr colorspace, the Y (luminance) component represents the black & white portion of the original image, and the Cb and Cr (chrominance) components represent the color portion of the original image. Originally, the analog equivalent of this transformation allowed the same signal to drive both black & white and color televisions, but JPEG images use YCbCr primarily because it allows the color data to be optionally subsampled for the purposes of reducing bandwidth or disk space. YCbCr is the most common JPEG colorspace, and YCbCr JPEG images can be compressed from and decompressed to any of the extended RGB pixel formats or grayscale, or they can be decompressed to YUV planar images.
    
    See Also:
    Constant Field Values
  - CS_GRAY
```
public static final int CS_GRAY
```
    Grayscale colorspace. The JPEG image retains only the luminance data (Y component), and any color data from the source image is discarded. Grayscale JPEG images can be compressed from and decompressed to any of the extended RGB pixel formats or grayscale, or they can be decompressed to YUV planar images.
    
    See Also:
    Constant Field Values
  - CS_CMYK
```
public static final int CS_CMYK
```
    CMYK colorspace. When compressing the JPEG image, the C, M, Y, and K components in the source image are reordered into image planes, but no colorspace conversion or subsampling is performed. CMYK JPEG images can only be decompressed to CMYK pixels.
    
    See Also:
    Constant Field Values
  - CS_YCCK
```
public static final int CS_YCCK
```
    YCCK colorspace. YCCK (AKA "YCbCrK") is not an absolute colorspace but rather a mathematical transformation of CMYK designed solely for storage and transmission. It is to CMYK as YCbCr is to RGB. CMYK pixels can be reversibly transformed into YCCK, and as with YCbCr, the chrominance components in the YCCK pixels can be subsampled without incurring major perceptual loss. YCCK JPEG images can only be compressed from and decompressed to CMYK pixels.

    Constant Field Values
  - FLAG_BOTTOMUP
```
public static final int FLAG_BOTTOMUP

    See Also:
    Constant Field Values
  - FLAG_FASTUPSAMPLE
```
public static final int FLAG_FASTUPSAMPLE
```
    When decompressing an image that was compressed using chrominance subsampling, use the fastest chrominance upsampling algorithm available in the underlying codec. The default is to use smooth upsampling, which creates a smooth transition between neighboring chrominance components in order to reduce upsampling artifacts in the decompressed image.
    
    See Also:
    Constant Field Values
  - FLAG_FASTDCT
```
public static final int FLAG_FASTDCT
```
    Use the fastest DCT/IDCT algorithm available in the underlying codec. The default if this flag is not specified is implementation-specific. For example, the implementation of TurboJPEG for libjpeg[-turbo] uses the fast algorithm by default when compressing, because this has been shown to have only a very slight effect on accuracy, but it uses the accurate algorithm when decompressing, because this has been shown to have a larger effect.
    
    See Also:
    Constant Field Values
  - FLAG_ACCURATEDCT
```
public static final int FLAG_ACCURATEDCT
```
    Use the most accurate DCT/IDCT algorithm available in the underlying codec. The default if this flag is not specified is implementation-specific. For example, the implementation of TurboJPEG for libjpeg[-turbo] uses the fast algorithm by default when compressing, because this has been shown to have only a very slight effect on accuracy, but it uses the accurate algorithm when decompressing, because this has been shown to have a larger effect.

  - FLAG_STOPONWARNING
```
public static final int FLAG_STOPONWARNING
```
    Immediately discontinue the current compression/decompression/transform operation if the underlying codec throws a warning (non-fatal error). The default behavior is to allow the operation to complete unless a fatal error is encountered.
    NOTE: due to the design of the TurboJPEG Java API, only certain methods (specifically, TJDecompressor.decompress*() methods with a void return type) will complete and leave the output image in a fully recoverable state after a non-fatal error occurs.
    
    See Also:
    Constant Field Values
  - FLAG_PROGRESSIVE
```
public static final int FLAG_PROGRESSIVE
```
    Use progressive entropy coding in JPEG images generated by compression and transform operations. Progressive entropy coding will generally improve compression relative to baseline entropy coding (the default), but it will reduce compression and decompression performance considerably.
