Method Detail

convert

public void convert(OutputStream outputStream,
           int objectIndex)
             throws IOException

Description copied from interface: Exporter

Converts the object at index objectIndex into the desired export type.

Specified by:

convert in interface Exporter<Array2DImage>

Parameters:

outputStream - the output stream for the output object

objectIndex - the index of the input object of type T in the associated observational file area

Throws:

IOException

convert

public void convert(Array2DImage array2DImage,
           OutputStream outputStream)
             throws IOException

Converts a 2D array file to a viewable image file.

Specified by:

convert in interface Exporter<Array2DImage>

Parameters:

outputStream - the output stream

array2DImage - the array2DImage object to convert

Throws:

IOException - if there is an exception writing to the stream or reading the image
