eclipse中使用Glide进行高斯模糊处理

1、下载Glide的jar包，地址：http://pan.baidu.com/s/1ge8ptIV

2、导入eclipse

3、创建类BlurTransformation继承import com.bumptech.glide.load.resource.bitmap.BitmapTransformation;

package com.it.utils;

import com.bumptech.glide.load.engine.bitmap_recycle.BitmapPool;
import com.bumptech.glide.load.resource.bitmap.BitmapTransformation;

import android.content.Context;
import android.graphics.Bitmap;
import android.renderscript.Allocation;
import android.renderscript.Element;
import android.renderscript.RenderScript;
import android.renderscript.ScriptIntrinsicBlur;

public class BlurTransformation extends BitmapTransformation {

    private RenderScript rs;

    public BlurTransformation(Context context) {
    	super(context);
        rs = RenderScript.create( context );
    }

    @Override
    protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) {
        Bitmap blurredBitmap = toTransform.copy( Bitmap.Config.ARGB_8888, true );

        // Allocate memory for Renderscript to work with
        Allocation input = Allocation.createFromBitmap(
            rs, 
            blurredBitmap, 
            Allocation.MipmapControl.MIPMAP_FULL, 
            Allocation.USAGE_SHARED
        );
        Allocation output = Allocation.createTyped(rs, input.getType());

        // Load up an instance of the specific script that we want to use.
        ScriptIntrinsicBlur script = ScriptIntrinsicBlur.create(rs, Element.U8_4(rs));
        script.setInput(input);

        // Set the blur radius
        script.setRadius(20);

        // Start the ScriptIntrinisicBlur
        script.forEach(output);

        // Copy the output to the blurred bitmap
        output.copyTo(blurredBitmap);

        toTransform.recycle();

        return blurredBitmap;
    }

    @Override
    public String getId() {
        return "blur";
    }
}

4、使用

       Glide.with(this).load(picUrl).bitmapTransform(new BlurTransformation(this),
new CenterCrop(this)).into(layCover);

       其中picUrl为图片URL，layCover为加载图片的ImageView
