Method Detail

setProperties

public void setProperties(java.lang.String prefix,
                          java.util.Properties props)

Description copied from class: AbstractImageFormatter

Set the properties of the image formatter.

Specified by:

setProperties in interface ImageFormatter

Specified by:

setProperties in interface PropertyConsumer

Overrides:

setProperties in class AbstractImageFormatter

Parameters:

prefix - a String used by the PropertyConsumer to prepend to each property value it wants to look up - setList.getProperty(prefix.propertyKey). If the prefix had already been set, then the prefix passed in should replace that previous value.

props - a Properties object that the PropertyConsumer can use to retrieve expected properties it can use for configuration.

makeClone

public ImageFormatter makeClone()

Description copied from class: AbstractImageFormatter

Create a new instance of the same type of formatter. If you are running in a multi-threaded environment, you'll need to provide a new instance of the formatter to each thread, since the image and graphics that are being drawn into for each thread are contained within.

Specified by:

makeClone in interface ImageFormatter

Specified by:

makeClone in class AbstractImageFormatter

Returns:

a new instance of this type of formatter, with the same properties set.

formatImage

public byte[] formatImage(java.awt.image.BufferedImage bi)

Description copied from class: AbstractImageFormatter

Convert a BufferedImage to a image file format...

Specified by:

formatImage in interface ImageFormatter

Specified by:

formatImage in class AbstractImageFormatter

Parameters:

bi - a BufferedImage..

getFormatLabel

public java.lang.String getFormatLabel()

Get the Image Type created by the ImageFormatter. These responses should adhere to the OGC WMT standard format labels. Some are listed in the WMTConstants interface file.

getGraphics

public java.awt.Graphics getGraphics(int width,
                                     int height)

Return the applicable Graphics to use to paint the layers into. If the internal BufferedImage hasn't been created yet, or has been set to null, then a new buffered Image is created, set to the size specified by the height and width. The ImageGenerator extends MapBean. Remember to dispose of the graphics object when you are done with it. Uses the BufferedImage.TYPE_INT_ARGB colormodel.

Specified by:

getGraphics in interface ImageFormatter

Overrides:

getGraphics in class AbstractImageFormatter

Parameters:

width - pixel width of Graphics.

height - pixel height of Graphics.

Returns:

java.awt.Graphics object to use.
