public class JAIJPEGWriter extends JAIWriter
The file is specified by the fileName attribute using any form acceptable to FileParameter.
If the confirmOverwrite parameter has value false, then this actor will overwrite the specified file if it exists without asking. If true (the default), then if the file exists, then this actor will ask for confirmation before overwriting.
FileParameter
Entity.ContainedObjectsIterator
Modifier and Type | Field and Description |
---|---|
IntRangeParameter |
quality
The quality of the file written.
|
Parameter |
restartInterval
The restart interval in number of JPEG Minimum Coded Units
(MCUs).
|
Parameter |
writeJFIFHeader
If true (the default), the encoder will write a JFIF
header, using a marker.The marker includes data such as
version number, x and y pixel density, pixel aspect ratio.
