All Implemented Interfaces:
MField, MFImage, X3DField
public class MFImage extends X3DConcreteField implements MFImage
This utility class provides a concrete implementation corresponding to MFImage X3D field type.

Warning: this is an abstract interface that cannot be instantiated as a concrete object. Java programmers typically only need to use concrete objects provided by the org.web3d.x3d.jsail classes.
Package hint: This specification class is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI). MFImage is an array of SFImage values.

Related field object: SFImage

      public void getPixels(int imageIndex, int[] pixels)
      Get the image pixel value in the given eventOut.

      The number of items in the pixels array will be width * height. If there are less items than this an ArrayIndexOutOfBoundsException will be generated. The integer values are represented according to the number of components.

      1 Component Images
      The integer has the intensity value stored in the lowest byte and can be obtained: 

          intensity = (pixel[i]     ) &0xFF;

      2 Component Images
      The integer has the transparency value stored in the lowest byte and the intensity in the next byte: 

          intensity = (pixel[i] >> 8) &0xFF;
    alpha     = (pixel[i]     ) &0xFF;

      3 Component Images
      The three color components are stored in the integer array as follows: 

          red   = (pixel[i] >> 16) &0xFF;
    green = (pixel[i] >>  8) &0xFF;
    blue  = (pixel[i]      ) &0xFF;

      4 Component Images
      The integer has the value stored in the array as follows: 

          red   = (pixel[i] >> 24) &0xFF;
    green = (pixel[i] >> 16) &0xFF;
    blue  = (pixel[i] >>  8) &0xFF;
    alpha = (pixel[i]      ) &0xFF;

      The width and height values must be greater than or equal to zero. The number of components is between 1 and 4. Any value outside of these bounds will generate an IllegalArgumentException.

      Specified by:
      getPixels in interface MFImage
      Parameters:
      imageIndex - the index of the selected image
      pixels - The array to copy pixel values into

      Copy a region of the argument RenderedImage to replace a portion of the current SFimage.

      The sub image set shall not resize the base image representation and therefore performs an intersection clip of the provided image. The user provided image shall be of the same format (pixel depth, pixel representation) as the original image obtained through the getImage() method.

      RenderedImages are row order from top to bottom. A 4x8 RenderImage is indexed as follows: 

      
 X >01234567
   ----------
 0 |********|
 1 |********|
 2 |********|
 3 |********|
 ^ ----------
 Y

 1 |********|
 0 |********|
 ^ ----------
 Y

      Note: The parameter srcYOffset is referenced to the RenderedImage object (indexed top to bottom).

      destinationXOffset - The initial x dimension (width) offset in the SFimage object that begins the region to receive the copy
      destinationYOffset - The initial y dimension (height) offset in the SFimage object that begins the region to receive the copy
