(1)使用自定义的ImageView
Xml代码

<jp.co.cyberagent.android.gpuimage.GPUImageView
    android:id="@+id/gpuimage"
    android:layout_width="wrap_content"
    android:layout_height="0dp"
    android:layout_gravity="center"
    android:layout_weight="1" />

Java代码

mImageView.setFilter(new GPUImageSepiaFilter()); // sepia
mImageView.setFilter(new GPUImageGrayscaleFilter()); // gray
mImageView.setFilter(new GPUImageSharpenFilter()); // sharp
mImageView.setFilter(new GPUImageSobelEdgeDetection()); // edge

原图

sepia后：


gray后：



sharp后：

edge后：



(2) 处理Assets中的文件

Java代码

// 读取图像
AssetManager as = getAssets();
InputStream is = null;
Bitmap bitmap = null;
try {
    is = as.open("dog.jpg");
    bitmap = BitmapFactory.decodeStream(is);
    is.close();
} catch (IOException e) {
    Log.e("MainActivity", "Error");
}
 
// 使用GPUImage处理图像
GPUImage gpuImage = new GPUImage(this);
gpuImage.setImage(bitmap);
gpuImage.setFilter(new GPUImageToonFilter());
bitmap = gpuImage.getBitmapWithFilterApplied();
 
// 在ImageView中显示处理后的图像
ImageView view = new ImageView(this);
view.setImageBitmap(bitmap);
setContentView(view);

(3)使用Photoshop的acv文件
Java代码

// 读取图像
AssetManager as = getAssets();
InputStream is = null;
Bitmap bitmap = null;
try {
    is = as.open("dog.jpg");
    bitmap = BitmapFactory.decodeStream(is);
    is.close();
} catch (IOException e) {
    Log.e("MainActivity", "Error");
}

// 读取Photoshop的acv文件
GPUImageToneCurveFilter filter = new GPUImageToneCurveFilter();
try {
    is = as.open("tone_curve.acv");
    filter.setFromCurveFileInputStream(is);
    is.close();
} catch (IOException e) {
    Log.e("MainActivity", "Error");
}

// 使用GPUImage处理图像
GPUImage gpuImage = new GPUImage(self);
gpuImage.setImage(bitmap);
gpuImage.setFilter(filter);
bitmap = gpuImage.getBitmapWithFilterApplied();

// 在ImageView中显示处理后的图像
ImageView view = new ImageView(self);
view.setImageBitmap(bitmap);
setContentView(view);
