Save resized images with Glide

Question

Is possible save an image resized with glide in a file? I' m using this code:

Glide
    .with(context)
    .load(path)
    .override(600, 200) 
    .centerCrop() 
    .into(imageViewResizeCenterCrop);

How i can do?

Thanks

Yes, it's possible. I'm using a SimpleTarget (a custom target in Glide parlance) descendant I created for this specific purpose. It's very simple to use. Here is the Target code:

import android.graphics.Bitmap;

import com.bumptech.glide.request.animation.GlideAnimation;
import com.bumptech.glide.request.target.SimpleTarget;

import java.io.FileOutputStream;
import java.io.IOException;

public class FileTarget extends SimpleTarget<Bitmap> {
    public FileTarget(String fileName, int width, int height) {
        this(fileName, width, height, Bitmap.CompressFormat.JPEG, 70);
    }
    public FileTarget(String fileName, int width, int height, Bitmap.CompressFormat format, int quality) {
        super(width, height);
        this.fileName = fileName;
        this.format = format;
        this.quality = quality;
    }
    String fileName;
    Bitmap.CompressFormat format;
    int quality;
    public void onResourceReady(Bitmap bitmap, GlideAnimation anim) {
            try {
                FileOutputStream out = new FileOutputStream(fileName);
                bitmap.compress(format, quality, out);
                out.flush();
                out.close();
                onFileSaved();
            } catch (IOException e) {
                e.printStackTrace();
                onSaveException(e);
            }
    }
    public void onFileSaved() {
        // do nothing, should be overriden (optional)
    }
    public void onSaveException(Exception e) {
        // do nothing, should be overriden (optional)
    }

}

And here is how you would use it within your own example:

Glide
    .with(context)
    .load(path)
    .asBitmap()
    .centerCrop()
    .into(new FileTarget(pathToDestination, 600, 200));

This code does not show the image on any view, it saves it directly to the destination.

You can do this using custom bitmap transform

Glide.with(this)
            .load(path)
            .bitmapTransform(new CropTransformation(this, 600, 200))
            .into(imageView);

Download CropTransformation

Inside

 public Resource<Bitmap> transform(Resource<Bitmap> resource, int outWidth, int outHeight) {`

Save bitmap before

 return BitmapResource.obtain(bitmap, mBitmapPool);
