Constructor Detail

Image8

public Image8(int width,
              int height,
              int nBands)

Creates image without setting any pixels.

Image8

public Image8(int width,
              int height,
              int nBands,
              boolean fillWithZeroes,
              boolean compatibleWithDisplay)

Creates image with pixels optionally set to zero.

Image8

public Image8(java.awt.image.BufferedImage bim)
       throws IncompatibleImageException

Use the BufferedImage to set the width, height and number of bands (channels) in this Image. Populate the pixel values in the image data array from the BufferedImage also.

Throws:

IncompatibleImageException

Method Detail

getGraphicsConfiguration

public static java.awt.GraphicsConfiguration getGraphicsConfiguration()

Get a reference to the GraphicsConfiguration object, which is the default one for the display system.

add

public void add(Image other)
         throws IncompatibleImageException

Description copied from interface: Image

Add pixel values from the other Image into the current data array. If other is larger than the data then the rectangle starting at the top left corner of other which overlaps the data will be used.

Specified by:

add in interface Image

Throws:

IncompatibleImageException

clone

public Image clone()

Returns a new Image8 object with the same data.

Specified by:

clone in interface Image

Specified by:

clone in class Image8or16Base

convertToImage8

public Image8 convertToImage8()

Simply returns this (not a clone).

Specified by:

convertToImage8 in interface Image

convertToImage16

public Image16 convertToImage16()

Specified by:

convertToImage16 in interface Image

convertToImage32

public Image32 convertToImage32()

Specified by:

convertToImage32 in interface Image

Project from plane to sphere.

Specified by:

inverseGnomonicProjection in interface Image

isRaw

public boolean isRaw()

Description copied from interface: Image
