Examples of ComponentSampleModel

ae.java.awt.image.ComponentSampleModel
This class represents image data which is stored such that each sample of a pixel occupies one data element of the DataBuffer. It stores the N samples which make up a pixel in N separate data array elements. Different bands may be in different banks of the DataBuffer. Accessor methods are provided so that image data can be manipulated directly. This class can support different kinds of interleaving, e.g. band interleaving, scanline interleaving, and pixel interleaving. Pixel stride is the number of data array elements between two samples for the same band on the same scanline. Scanline stride is the number of data array elements between a given sample and the corresponding sample in the same column of the next scanline. Band offsets denote the number of data array elements from the first data array element of the bank of the DataBuffer holding each band to the first sample of the band. The bands are numbered from 0 to N-1. This class can represent image data for which each sample is an unsigned integral number which can be stored in 8, 16, or 32 bits (using DataBuffer.TYPE_BYTE, DataBuffer.TYPE_USHORT, or DataBuffer.TYPE_INT, respectively), data for which each sample is a signed integral number which can be stored in 16 bits (using DataBuffer.TYPE_SHORT), or data for which each sample is a signed float or double quantity (using DataBuffer.TYPE_FLOAT or DataBuffer.TYPE_DOUBLE, respectively). All samples of a given ComponentSampleModel are stored with the same precision. All strides and offsets must be non-negative. This class supports {@link DataBuffer#TYPE_BYTE TYPE_BYTE}, {@link DataBuffer#TYPE_USHORT TYPE_USHORT}, {@link DataBuffer#TYPE_SHORT TYPE_SHORT}, {@link DataBuffer#TYPE_INT TYPE_INT}, {@link DataBuffer#TYPE_FLOAT TYPE_FLOAT}, {@link DataBuffer#TYPE_DOUBLE TYPE_DOUBLE}, @see ae.java.awt.image.PixelInterleavedSampleModel @see ae.java.awt.image.BandedSampleModel
