Class MultiPixelPackedSampleModel
MultiPixelPackedSampleModel provides a single band model that supports
multiple pixels in a single unit. Pixels have 2^n bits and 2^k pixels fit
per data element.

MultiPixelPackedSampleModel
public MultiPixelPackedSampleModel(int dataType,
int w,
int h,
int numberOfBits,
int scanlineStride,
int dataBitOffset)
createDataBuffer
public DataBuffer createDataBuffer()
Creates a DataBuffer for holding pixel data in the format and
layout described by this SampleModel. The returned buffer will
consist of one single bank.
- createDataBuffer in interface SampleModel
getDataElements
public Object getDataElements(int x,
int y,
Object obj,
DataBuffer data)
Extract one pixel and return in an array of transfer type.
Extracts the pixel at x, y from data and stores into the 0th index of the
array obj, since there is only one band. If obj is null, a new array of
getTransferType() is created.
- getDataElements in interface SampleModel
x
- The x-coordinate of the pixel rectangle to store in obj
.y
- The y-coordinate of the pixel rectangle to store in obj
.obj
- The primitive array to store the pixels into or null to force creation.data
- The DataBuffer that is the source of the pixel data.
- The primitive array containing the pixel data.
