        int[] bankIndices, int[] bandOffsets, Point location) 

Source Link

Document

Creates a Raster based on a BandedSampleModel with the specified DataBuffer, width, height, scanline stride, bank indices, and band offsets.

Usage

From source file:TestImage2.java

public static RenderedImage toRenderedImage(String[] rows) {
    // Create the DataBuffer to hold the pixel samples
    final int width = rows[0].length();
    final int height = rows.length;
    final int size = width * height;
    byte[] pixels = new byte[size];
    int index = 0;
    for (String row : rows) {
        for (int x = 0; x < width; x++) {
            pixels[index++] = (byte) decodeGray(row.charAt(x));
        }//from  ww  w . ja v  a 2s.c o  m
    }
    DataBuffer dataBuffer = new DataBufferByte(pixels, size);

    // Create Raster
    WritableRaster writableRaster = Raster.createBandedRaster(dataBuffer, width, height, width, // scanlineStride
            new int[] { 0 }, // bankIndices,
            new int[] { 0 }, // bandOffsets,
            null); // location

    // Create the image
    BufferedImage bufferedImage = new BufferedImage(width, height, BufferedImage.TYPE_BYTE_GRAY);
    bufferedImage.setData(writableRaster);

    return bufferedImage;
}
