    Returns the 'default' encoded COLOR_ID for a given ColorModel. This method is not needed in the simple case of encoding Buffered Images (the library will figure things out for you). It can be useful for encoding Rasters. To determine what needs to be done to the image prior to encoding.
    
    指定者:
    
    getDefaultColorId 在接口中 JPEGImageEncoder
    
    参数:
    
    var1 - The ColorModel to map to an jpeg encoded COLOR_ID.
    
    返回:
    
    The default mapping of cm to a jpeg Color_ID note that in a few cases color conversion is required.

    Set the JPEGEncodeParam object that is to be used for future encoding operations. 'jep' is copied so changes will not be tracked, unless you call this method again.

    参数:
    
    var1 - The JPEGEncodeParam object to use for future encodings.

```
    从接口复制的说明: JPEGImageEncoder
    
    This is a factory method for creating JPEGEncodeParam objects. It is the users responsiblity to match the colorID with the data contained in the Raster. Failure to do so may lead to either poor compression or poor image quality. If you don't understand much about JPEG it is strongly reccomended that you stick to the BufferedImage interfaces.

public JPEGEncodeParam getDefaultJPEGEncodeParam(BufferedImage var1)

    This is a factory method for creating JPEGEncodeParam objects. The returned object will do a credible job of encoding the given BufferedImage.

    getDefaultJPEGEncodeParam 在接口中 JPEGImageEncoder
  - getDefaultJPEGEncodeParam
```
public JPEGEncodeParam getDefaultJPEGEncodeParam(int var1,

```
    从接口复制的说明: JPEGImageEncoder
    
    This is a factory method for creating JPEGEncodeParam objects. It is the users responsiblity to match the colorID with the given number of bands, which should match the data being encoded. Failure to do so may lead to poor compression and/or poor image quality. If you don't understand much about JPEG it is strongly recommended that you stick to the BufferedImage interface.
    
    指定者:
    
    getDefaultJPEGEncodeParam 在接口中 JPEGImageEncoder
    
    参数:
    
    var1 - the number of bands that will be encoded (max of four).
    
    var2 - the COLOR_ID for the encoded data. This is used to set reasonable defaults in the parameter object. This must match the number of bands given.
  - getDefaultJPEGEncodeParam
```
public JPEGEncodeParam getDefaultJPEGEncodeParam(JPEGDecodeParam var1)

```
    从接口复制的说明: JPEGImageEncoder
    
    This is a factory method for creating a JPEGEncodeParam from a JPEGDecodeParam. This will return a new JPEGEncodeParam object that is initialized from the JPEGDecodeParam object. All major pieces of information will be initialized from the DecodeParam (Markers, Tables, mappings).
    
    指定者:
    
    getDefaultJPEGEncodeParam 在接口中 JPEGImageEncoder

```
    从接口复制的说明: JPEGImageEncoder
    
    Encode a BufferedImage as a JPEG data stream. Note, some color conversions may takes place. The current JPEGEncodeParam's encoded COLOR_ID should match the value returned by getDefaultColorID when given the BufferedImage's ColorModel.
    If no JPEGEncodeParam object has been provided yet a default one will be created by calling getDefaultJPEGEncodeParam with bi.

    从接口复制的说明: JPEGImageEncoder
    
    Encode a BufferedImage as a JPEG data stream. Note, some color conversions may takes place. The jep's encoded COLOR_ID should match the value returned by getDefaultColorID when given the BufferedImage's ColorModel.

    从接口复制的说明: JPEGImageEncoder
    
    Encode a Raster as a JPEG data stream. Note that no color conversion takes place. It is required that you match the Raster to the encoded COLOR_ID contained in the current JPEGEncodeParam object.
