public class JAIPNMWriter
- extends JAIWriter
Write a javax.media.jai.RenderedOp to a specified PNM file.
PNM is an extension of the portable bitmap file format.
The file is specified by the fileName attribute
using any form acceptable to FileParameter.
If the writeRawData parameter has value true, then
this actor will write in binary. If true (the default), then
then the actor will write ASCII data.
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.

writeRawData
public Parameter writeRawData
- If true, then write raw binary data.
If false (the default), then write the data in ASCII.

java.lang.String name)
throws IllegalActionException,
NameDuplicationException
- Construct an actor with the given container and name.
- Parameters:
container
- The container.name
- The name of this actor.
- Throws:
IllegalActionException
- If the actor cannot be contained
by the proposed container.
NameDuplicationException
- If the container already has an
actor with this name.
postfire
public boolean postfire()
throws IllegalActionException
- Read an input JAIImageToken and write it to the file.
If the file does not exist then create it. If the file
already exists, then query the user for overwrite.
- Specified by:
postfire
in interface Executable
- Overrides:
postfire
in class JAIWriter
- Returns:
- True if the execution can continue.
- Throws:
IllegalActionException
- If the file cannot be opened
or created, if the user refuses to overwrite an existing file,
of if the image in unable to be encoded.
