Field Detail

os

private final java.io.OutputStream os

The OutputStream to which the thumbnail image is to be written to.

Constructor Detail

OutputStreamImageSink

public OutputStreamImageSink(java.io.OutputStream os)

Instantiates an OutputStreamImageSink with the OutputStream to which the thumbnail should be written to.

Parameters:

os - The OutputStream to write the thumbnail to.

Throws:

java.lang.NullPointerException - If the OutputStream is null.

Method Detail

write

public void write(java.awt.image.BufferedImage img)
           throws java.io.IOException

Writes the resulting image to the OutputStream.

Specified by:

write in interface ImageSink<java.io.OutputStream>

Overrides:

write in class AbstractImageSink<java.io.OutputStream>

Parameters:

img - The image to write.

Throws:

UnsupportedFormatException - When an unsupported format has been specified by the AbstractImageSink.setOutputFormatName(String) method.

java.io.IOException - When a problem occurs while writing the image.

java.lang.NullPointerException - If the image is null.

java.lang.IllegalStateException - If the output format has not been set by calling the AbstractImageSink.setOutputFormatName(String) method.

setCompressionModeExplicit

private void setCompressionModeExplicit(javax.imageio.ImageWriteParam writeParam)

Sets the compression mode to explicit, if not already. A check exists to prevent setting the explicit mode more than once, as any previously set parameters will be discarded.

Parameters:

writeParam - Current image writer parameters.

isJpegOrBmp

private boolean isJpegOrBmp(java.lang.String formatName)

isPng

private boolean isPng(java.lang.String formatName)

isDefaultPngWriter

private boolean isDefaultPngWriter(javax.imageio.ImageWriter writer)

isJava9OrNewer

private boolean isJava9OrNewer()

getSink

public java.io.OutputStream getSink()

Description copied from interface: ImageSink

Returns the destination to which the thumbnail will be stored or written.

Returns:

The destination for the thumbnail image.
