兩個庫擁有許多特性，以下列入部分特性比較
Picasso (CircleTransform.Java)
import android.graphics.Bitmap;
import com.squareup.picasso.Transformation;
public class CircleTransform implements Transformation { @Override public Bitmap
transform(Bitmap source) {
return ImageUtils.getCircularBitmapImage(source); }
@Override public String
key() {
return "circle-image"; } }
Glide (CircleTransform.Java)
import android.content.Context;
import android.graphics.Bitmap;
import com.bumptech.glide.load.engine.bitmap_recycle.BitmapPool;
import com.bumptech.glide.load.resource.bitmap.BitmapTransformation;
public class GlideCircleTransform extends BitmapTransformation { public GlideCircleTransform(Context context) {
super(context); }
@Override protected Bitmap
transform(BitmapPool pool, Bitmap source,
int outWidth,
int outHeight) {
return ImageUtils.getCircularBitmapImage(source); }
@Override public String
getId() {
return "Glide_Circle_Transformation"; } }
ImageUtils.java
import android.graphics.Bitmap;
import android.graphics.BitmapShader;
import android.graphics.Canvas;
import android.graphics.Paint;
public class ImageUtils { public static Bitmap
getCircularBitmapImage(Bitmap source) {
int size = Math.min(source.getWidth(), source.getHeight());
int x = (source.getWidth() - size) /
2;
int y = (source.getHeight() - size) /
2; Bitmap squaredBitmap = Bitmap.createBitmap(source, x, y, size, size);
if (squaredBitmap != source) { source.recycle(); } Bitmap bitmap = Bitmap.createBitmap(size, size, Bitmap.Config.ARGB_8888); Canvas canvas =
new Canvas(bitmap); Paint paint =
new Paint(); BitmapShader shader =
new BitmapShader(squaredBitmap, BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP); paint.setShader(shader); paint.setAntiAlias(
true);
float r = size /
2f; canvas.drawCircle(r, r, r, paint); squaredBitmap.recycle();
return bitmap; } }
package com.app.client;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
import com.bumptech.glide.Glide;
public class MainActivity extends Activity {private ImageView imageView;
private Button show;
@Overrideprotected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);imageView = (ImageView) findViewById(R.id.imageId);show = (Button) findViewById(R.id.btn);show.setOnClickListener(
new View.OnClickListener() {
@Overridepublic void onClick(View v) {Glide.with(MainActivity.
this).load(
"https://img-blog.csdn.net/20160606102355573").transform(
new CircleTransform(getApplicationContext())).into(imageView);}});}
@Overrideprotected void onDestroy() {
super.onDestroy();}
}
