Method Detail

createScript

public void createScript()

Generate the script.

Specified by:

createScript in interface ScriptGenerator

writeHeader

protected void writeHeader()

Write the header of the script. This method must be implemented by subclasses.

getSearchPath

protected java.lang.String getSearchPath()

Return the search-path in a plattform-dependent way.

writeCommand

protected void writeCommand()

Write the ImageCommand to the script-file. This is a default implementation which should do for most cases.

getScriptArg

protected java.lang.String getScriptArg(java.lang.String pToken)

Return the token as a script-argument. Normally, the argument token is only part of the script-argument if it contains a [wxh+x+y]-read-spec.

This method must be implemented by subclasses.

quote

protected java.lang.String quote(java.lang.String pString)

Quote the given string. This method must be implemented by subclasses.

writeOperation

protected void writeOperation()

Write the Operation to the script-file.

init

public void init(java.io.PrintWriter pWriter,
                 Operation pOp,
                 java.util.Properties pProps)

Intialize the generator.

Specified by:

init in interface ScriptGenerator

getWriter

public java.io.PrintWriter getWriter()

Return the PrintWriter-object.

getOperation

public Operation getOperation()

Return the Operation-object.

getProperties

public java.util.Properties getProperties()

Return the Properties-object.
