Class ImageDataInfo

java.lang.Object

eve.data.DataObject

eve.sys.ImageDataInfo

All Implemented Interfaces:

DataUnit, ImageData, Copyable, Comparable

public class ImageDataInfo
extends DataObject
implements ImageData

This class contains the same information that you get from an ImageData, but as publicly accessible fields instead of via method calls. This can be used to improve performance when making multiple calls to methods that need this information.

getPixels

public int[] getPixels(int[] dest,
                       int offset,
                       int x,

This does nothing at all - always returns null.

Specified by:

getPixels in interface ImageData

Parameters:

dest - The destination int array. If this is null then a new array should be created.

offset - The offset into the array to start placing pixels.

x - the x co-ordinate within the image.

y - the y co-ordinate within the image.

width - the width of the pixel block to get.

height - the height of the pixel block to get.

rowStride - the number of int values between each row in the destination int array. If this is 0 it will be assumed to be equal to width.

Returns:

The array containing the pixels, or null if getting pixels is not supported.

setPixels

public boolean setPixels(int[] src,
                         int offset,
                         int x,

                         int width,
                         int height,
                         int rowStride)

This does nothing at all - always returns false.

Specified by:

setPixels in interface ImageData

Parameters:

src - The source int array.

offset - The offset into the array to start retrieving pixels.

x - the x co-ordinate within the image.

y - the y co-ordinate within the image.

width - the width of the pixel block to get.

height - the height of the pixel block to get.

rowStride - the number of int values between each row in the source int array. If this is 0 it will be assumed to be equal to width.

Returns:

true if setting pixel values is supported, false if not.

setScanLinePixels

public boolean setScanLinePixels(int scanLine,
                                 int[] pixels,
                                 int offset,
