Constructor Detail

ByteArrayChart

public ByteArrayChart(Chart chart)
               throws java.io.IOException

Creates a shallow byte array copy of given chart. The copy will have no references back to the original chart object, except if the source chart is an instance of a byte array chart, in which case the new chart will share it's encoded image byte array with the source chart, along with all the other chart members.

Parameters:

chart - chart to be copied

ByteArrayChart

public ByteArrayChart(java.lang.Number width,
                      java.lang.Number height,
                      java.lang.Number resolution,
                      java.lang.String contentType,
                      java.util.List annotatedShapes,
                      byte[] content)

Creates and initializes a new byte array chart. In particular, the given content becomes the internal byte array.

Parameters:

width - chart width, in millimeters (may be null)

height - chart height, in millimeters (may be null)

resolution - resolution, in pixels-per-millimeters (may be null)

contentType - chart content MIME type

annotatedShapes - list of serializable annotated shapes

content - encoded chart content

Method Detail

putContent

public void putContent(java.io.OutputStream stream)
                throws java.io.IOException

Puts the chart content into given stream.

Parameters:

stream - stream to write chart content into

Throws:

java.io.IOException - if an I/O error occurs

See Also:

AbstractChart.getContentType()

getBuffer

public byte[] getBuffer()

Gets a reference to the internal byte array.

getContent

public java.io.InputStream getContent()

Gets a new input stream containing the encoded chart image data.
