Java java.awt.image Class PixelInterleavedSampleModel（JDK8）

Constructor Detail

• PixelInterleavedSampleModel

  public PixelInterleavedSampleModel(int dataType,
                                     int w,
                                     int h,
                                     int pixelStride,
                                     int scanlineStride,
                                     int[] bandOffsets)

  Constructs a PixelInterleavedSampleModel with the specified parameters. The number of bands will be given by the length of the bandOffsets array.

  Parameters:

  dataType - The data type for storing samples.

  w - The width (in pixels) of the region of image data described.

  h - The height (in pixels) of the region of image data described.

  pixelStride - The pixel stride of the image data.

  scanlineStride - The line stride of the image data.

  bandOffsets - The offsets of all bands.

  Throws:

  IllegalArgumentException - if w or h is not greater than 0

  IllegalArgumentException - if any offset between bands is greater than the scanline stride

  IllegalArgumentException - if the product of pixelStride and w is greater than scanlineStride

  IllegalArgumentException - if pixelStride is less than any offset between bands

  IllegalArgumentException - if dataType is not one of the supported data types

Method Detail

• createCompatibleSampleModel

  public SampleModel createCompatibleSampleModel(int w,
                                                 int h)

  Creates a new PixelInterleavedSampleModel with the specified width and height. The new PixelInterleavedSampleModel will have the same number of bands, storage data type, and pixel stride as this PixelInterleavedSampleModel. The band offsets may be compressed such that the minimum of all of the band offsets is zero.

  Overrides:

  createCompatibleSampleModel in class ComponentSampleModel

  Parameters:

  w - the width of the resulting SampleModel

  h - the height of the resulting SampleModel

  Returns:

  a new SampleModel with the specified width and height.

  Throws:

  IllegalArgumentException - if w or h is not greater than 0

• createSubsetSampleModel

  public SampleModel createSubsetSampleModel(int[] bands)

  Creates a new PixelInterleavedSampleModel with a subset of the bands of this PixelInterleavedSampleModel. The new PixelInterleavedSampleModel can be used with any DataBuffer that the existing PixelInterleavedSampleModel can be used with. The new PixelInterleavedSampleModel/DataBuffer combination will represent an image with a subset of the bands of the original PixelInterleavedSampleModel/DataBuffer combination.

  Overrides:

  createSubsetSampleModel in class ComponentSampleModel

  Parameters:

  bands - a subset of bands from this ComponentSampleModel

  Returns:

  a ComponentSampleModel created with a subset of bands from this ComponentSampleModel.

• hashCode

  public int hashCode()

  Description copied from class: Object
  Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

  The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the Object.equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

  As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

  Overrides:

  hashCode in class ComponentSampleModel

  Returns:

  a hash code value for this object.
