C++和java联合开发屏幕截图程序，存在Raster和ColorModel不兼容问题

Question

这个问题很专业，csdn肯定答不出来，建议到 forum.java.sun.com出看看

Answer 1

data = s.getCaptureData();
int length = data.length;
    int[] masks = new int[3]; 
    masks[0] = 0xff0000;
    masks[1] = 0x00ff00;
    masks[2] = 0x0000ff;
    
DataBuffer db = new DataBufferInt(data, length);
   SinglePixelPackedSampleModel sm = new SinglePixelPackedSampleModel(DataBuffer.TYPE_INT,s.getWidth(),s.getHeight(),masks);
   ColorModel cm = new DirectColorModel(32,0xff0000,0x00ff00,0x0000ff);
WritableRaster wr =
Raster.createWritableRaster(sm, db,null);
img = new BufferedImage(cm, wr, false, null);

Answer 2

DirectColorModel应该是24bit，或者masks用4个bank
