java.lang.Object | +--javax.media.jai.UnpackedImageData
This class is used by PixelAccessor to store unpacked
image data and the information needed to access it. The data are stored in
a two-dimensional primitive array.
| Field Summary | |
int[] |
bandOffsets
The number of array elements from the beginning of the data array to the first pixel of the Rectangle for all bands. |
boolean |
convertToDest
Indicates whether the PixelAccessor can and must set the
data back into the Raster. |
Object |
data
The data array supplied to store the unpacked data. |
int |
lineStride
The number of array elements per scanline. |
int |
pixelStride
The number of array elements to skip to get to the next pixel on the same scanline. |
Raster |
raster
The Raster containing the pixel data. |
Rectangle |
rect
The rectangular region within the Raster where the
data are to be accessed. |
int |
type
The type of the primitive array used to store the data. |
| Constructor Summary | |
UnpackedImageData(Raster raster,
Rectangle rect,
int type,
Object data,
int pixelStride,
int lineStride,
int[] bandOffsets,
boolean convertToDest)
Constructs a PackedImageRaster. |

getDoubleData()
Returns the two-dimensional double data array, or null
if the data are not stored in a double array. |
double[] |
getDoubleData(int b)
Returns double data array for a specific band, or null
if the data are not stored in a double array. |
float[][] |
getFloatData()
Returns the two-dimensional float data array, or null
if the data are not stored in a float array. |
float[] |
getFloatData(int b)
Returns float data array for a specific band, or null
if the data are not stored in a float array. |
int[][] |
getIntData()
Returns the two-dimensional integer data array, or null
if the data are not stored in an integer array. |
int[] |
getIntData(int b)
Returns integer data array for a specific band, or null
if the data are not stored in an integer array. |
int |
getMaxOffset()
Returns the maximum offset of all bands. |
int |
getMinOffset()
Returns the minimum offset of all bands. |
int |
getOffset(int b)
Returns the offset for a band. |
short[][] |
getShortData()
Returns the two-dimensional short data array, or null
if the data are not stored in a short array. |
short[] |
getShortData(int b)
Returns short data array for a specific band, or null
if the data are not stored in a short array. |

raster - The Raster containing the pixel data.rect - The rectangular region containing the data.type - The type of the primitive array supplied to store the data.data - The data array supplied to store the data.pixelStride - The data array increment needed to move from band x
of pixel i to band x of pixel i+1 on the same
scanline.lineStride - The data array increment to move from the pixel x
of line i to pixel x of line i+1.bandOffsets - The number of bytes from the start of the data array
to the location of the first pixel of the rectangle
for all bands.convertToDest - A boolean indicating whether the data can and
must be set back into the Raster. This applies
only to destinations.| Method Detail |
