示例1: main
import java.awt.image.ColorModel; //导入方法依赖的package包/类
public static void main(String[] args) throws IIOInvalidTreeException {
// getting the writer for the png format
Iterator iter = ImageIO.getImageWritersByFormatName("png");
ImageWriter writer = (ImageWriter) iter.next();
// creating a color model
ColorModel colorModel = ColorModel.getRGBdefault();
// creating a sample model
SampleModel sampleModel = colorModel.createCompatibleSampleModel(640, 480);
// creating a default metadata object
IIOMetadata metaData = writer.getDefaultImageMetadata(new ImageTypeSpecifier(colorModel, sampleModel), null);
String formatName = metaData.getNativeMetadataFormatName();
// first call
Node metaDataNode = metaData.getAsTree(formatName);
try {
metaData.setFromTree(formatName, metaDataNode);
} catch (Exception ex) {
ex.printStackTrace();
}
// second call (bitdepht is already set to an invalid value)
metaDataNode = metaData.getAsTree(formatName);
metaData.setFromTree(formatName, metaDataNode);
}
示例2: getGrayscale
import java.awt.image.ColorModel; //导入方法依赖的package包/类
/**
*
* @param width The image width (height derived from buffer length)
* @param buffer The buffer containing raw grayscale pixel data
*
* @return THe grayscale image
*/
public static BufferedImage getGrayscale(int width, byte[] buffer) {
int height = buffer.length / width;
ColorSpace cs = ColorSpace.getInstance(ColorSpace.CS_GRAY);
int[] nBits = { 8 };
ColorModel cm = new ComponentColorModel(cs, nBits, false, true, Transparency.OPAQUE, DataBuffer.TYPE_BYTE);
SampleModel sm = cm.createCompatibleSampleModel(width, height);
DataBufferByte db = new DataBufferByte(buffer, width * height);
WritableRaster raster = Raster.createWritableRaster(sm, db, null);
BufferedImage result = new BufferedImage(cm, raster, false, null);
return result;
