- Method Detail
  - encode
```
byte[] encode(java.awt.image.RenderedImage image)
       throws java.io.IOException
```
    Encodes an AWT image into a byte array in a particular format.
    
    Throws:
    
    java.io.IOException
  - getQuality
```
float getQuality()
```
    Return the quality of the image encoding.
  - setQuality
```
void setQuality(float quality)
```
    Sets the quality of the image encoding. Simply does nothing if the encoder does not support it.
  - isEncodingAlpha
```
boolean isEncodingAlpha()
```
    Returns whether to encode the alpha transparency.
  - setEncodingAlpha
```
void setEncodingAlpha(boolean encodeAlpha)
```
    Sets whether to encode the alpha transparency. Simply does nothing if the encoder does not support it.
