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.
getDataElements
public Object getDataElements(int x,
int y,
Object obj,
DataBuffer data)
Extract all samples of one pixel and return in an array of transfer type.
Extracts the pixel at x, y from data and stores samples into the array
obj. If obj is null, a new array of getTransferType() is created.
- getDataElements in interface ComponentSampleModel
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.
getPixels
public int[] getPixels(int x,
int y,
int w,
int h,
int[] iArray,
DataBuffer data)
Copy pixels from a region into an array.
Copies the samples of the pixels in the rectangle starting at x, y that
is w pixels wide and h scanlines high. When there is more than one band,
the samples stored in order before the next pixel. This ordering isn't
well specified in Sun's docs as of 1.4.2.
If iArray is null, a new array is allocated, filled, and returned.
- getPixels in interface ComponentSampleModel
x
- The x-coordinate of the pixel rectangle to store in
iArray
.y
- The y-coordinate of the pixel rectangle to store in
iArray
.w
- The width in pixels of the rectangle.h
- The height in pixels of the rectangle.iArray
- The int 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.
getSamples
public int[] getSamples(int x,
int y,
int w,
int h,
int b,
int[] iArray,
DataBuffer data)
Copy one band's samples from a region into an array.
Copies from one band the samples of the pixels in the rectangle starting
at x, y that is w pixels wide and h scanlines high.
If iArray is null, a new array is allocated, filled, and returned.
- getSamples in interface SampleModel
x
- The x-coordinate of the pixel rectangle to store in
iArray
.y
- The y-coordinate of the pixel rectangle to store in
iArray
.w
- The width in pixels of the rectangle.h
- The height in pixels of the rectangle.b
- The band to retrieve.iArray
- The int 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.
setDataElements
public void setDataElements(int x,
int y,
Object obj,
DataBuffer data)
Set the pixel at x, y to the value in the first element of the primitive
array obj.
- setDataElements in interface ComponentSampleModel
x
- The x-coordinate of the data elements in obj
.y
- The y-coordinate of the data elements in obj
.obj
- The primitive array containing the data elements to set.data
- The DataBuffer to store the data elements into.
toString
public String toString()
Creates a String with some information about this SampleModel.
- toString in interface Object
- A String describing this SampleModel.
