    Set the pixel size units This value is copied into the APP0 marker (if that marker is written). This value isn't used by the JPEG code.
    
    指定者:
    
    setDensityUnit 在接口中 JPEGEncodeParam
    
    参数:
    
    var1 - One of the DENSITY_UNIT_* values.

    Set the horizontal pixel density This value is written into the APP0 marker. It isn't used by the JPEG code.
    
    指定者:
    
    setXDensity 在接口中 JPEGEncodeParam
    
    参数:
    
    var1 - the horizontal pixel density, in units described by @see JPEGParam.getDensityUnit.

    Set the vertical pixel density. This value is copied into the JFIF APP0 marker. It isn't used by the JPEG code.
    
    指定者:
    
    setYDensity 在接口中 JPEGEncodeParam

    This creates new Quantization tables that replace the currently installed Quantization tables. It also updates the Component QTable mapping to the default for the current encoded COLOR_ID.
    The Created Quantization table varies from very high compression, very low quality, (0.0) to low compression, very high quality (1.0) based on the quality parameter.
    
    At a quality level of 1.0 the table will be all 1's which will lead to no loss of data due to quantization (however chrominace subsampling, if used, and roundoff error in the DCT will still degrade the image some what).
    
    This is a linear manipulation of the standard Chrominance Q-Table.
```
Some guidelines: 0.75 high quality
                 0.5  medium quality
                 0.25 low quality
 
```
    指定者:
    
    setQuality 在接口中 JPEGEncodeParam
    
    参数:
    
    var1 - 0.0-1.0 setting of desired quality level.
    
    var2 - force baseline quantization table
  - getDefaultColorId

public static int getDefaultColorId(ColorModel var0)
