List of lookupPixel() Examples

Examples of lookupPixel()

java.awt.image.ByteLookupTable.lookupPixel()
Returns an array of samples of a pixel, translated with the lookup table. The source and destination array can be the same array. Array dst is returned. @param src the source array. @param dst the destination array. This array must be at least as long as src. If dst is null, a new array will be allocated having the same length as src. @return the array dst, an int array of samples. @exception ArrayIndexOutOfBoundsException if src is longer than dst or if for any element i of src, src[i]-offset is either less than zero or greater than or equal to the length of the lookup table for any band.
java.awt.image.LookupTable.lookupPixel()
Returns an int array of components for one pixel. The dest array contains the result of the lookup and is returned. If dest is null, a new array is allocated. The source and destination can be equal. @param src the source array of components of one pixel @param dest the destination array of components for one pixel,translated with this LookupTable @return an int array of components for one pixel.
java.awt.image.ShortLookupTable.lookupPixel()
Returns an array of samples of a pixel, translated with the lookup table. The source and destination array can be the same array. Array dst is returned. @param src the source array. @param dst the destination array. This array must be at least as long as src. If dst is null, a new array will be allocated having the same length as src. @return the array dst, an int array of samples. @exception ArrayIndexOutOfBoundsException if src is longer than dst or if for any element i of src, (src[i]&0xffff)-offset is either less than zero or greater than or equal to the length of the lookup table for any band.
