| KeypointPNGEncoderAdapter | | public class KeypointPNGEncoderAdapter implements ImageEncoder(Code) | | Adapter class for the Keypoint PNG Encoder. The ImageEncoderFactory will
only return a reference to this class by default if the library has been
compiled under a JDK < 1.4 or is being run using a JDK < 1.4.

| Method Summary | |
| public byte[] | encode(BufferedImage bufferedImage)
Encodes an image in PNG format.
Parameters:
bufferedImage - The image to be encoded. | | public void | encode(BufferedImage bufferedImage, OutputStream outputStream)
Encodes an image in PNG format and writes it to an
OutputStream. | | public float | getQuality()
Get the quality of the image encoding. | | public boolean | isEncodingAlpha()
Get whether the encoder should encode alpha transparency. | | public void | setEncodingAlpha(boolean encodingAlpha)
Set whether the encoder should encode alpha transparency (supported). | | public void | setQuality(float quality)
Set the quality of the image encoding (supported). |
| encode | | public byte[] encode(BufferedImage bufferedImage) throws IOException(Code) | | Encodes an image in PNG format.
Parameters:
bufferedImage - The image to be encoded. The byte[] that is the encoded image.
throws:
IOException - |
| encode | | public void encode(BufferedImage bufferedImage, OutputStream outputStream) throws IOException(Code) | | Encodes an image in PNG format and writes it to an
OutputStream.
Parameters:
bufferedImage - The image to be encoded.
Parameters:
outputStream - The OutputStream to write the encoded image to.
throws:
IOException - |
| getQuality | | public float getQuality()(Code) | | Get the quality of the image encoding. The underlying encoder uses int
values: 0 for no compression, and values 1 through 9 for various levels
of compression (1 is best speed, 9 is best compression).
A float representing the quality. |
| isEncodingAlpha | | public boolean isEncodingAlpha()(Code) | | Get whether the encoder should encode alpha transparency.
Whether the encoder is encoding alpha transparency. |
| setEncodingAlpha | | public void setEncodingAlpha(boolean encodingAlpha)(Code) | | Set whether the encoder should encode alpha transparency (supported).
Parameters:
encodingAlpha - Whether the encoder should encode alpha transparency. |
| setQuality | | public void setQuality(float quality)(Code) | | Set the quality of the image encoding (supported). The underlying
encoder uses int values: 0 for no compression, and values 1 through 9
for various levels of compression (1 is best speed, 9 is best
compression).
Parameters:
quality - A float representing the quality. |
