j2me图片缩放方法

注:src为原始图片，destW为修改后的宽度，destH为修改后的高度



1.方法一
public static Image resizeImage(Image src, int destW, int destH) {   
        int srcW = src.getWidth();   
        int srcH = src.getHeight();   
        int[] destPixels = new int[destW * destH];  
        int[] srcPixels = new int[srcW * srcH];    
        src.getRGB(srcPixels, 0, srcW, 0, 0, srcW, srcH);   
        for (int destY = 0; destY < destH; ++destY) {   
            for (int destX = 0; destX < destW; ++destX) {   
                int srcX = (destX * srcW) / destW; 
                int srcY = (destY * srcH) / destH; 
                destPixels[destX + destY * destW] = srcPixels[srcX + srcY * srcW];   
            }   
        }   
        return Image.createRGBImage(destPixels, destW, destH, true);   
   }  

2.方法二
public static Image ZoomImage(Image src, int desW, int desH) { 
        Image desImg = null; 
        int srcW = src.getWidth(); // 原始图像宽 
        int srcH = src.getHeight(); // 原始图像高 
        int[] srcBuf = new int[srcW * srcH]; // 原始图片像素信息缓存 
        src.getRGB(srcBuf, 0, srcW, 0, 0, srcW, srcH); 
        // 计算插值表 
        int[] tabY = new int[desH];
