有没有办法将图像作为位图加载到 Glide

Question

Im looking for a way to use bitmap as input to Glide. I am even not sure if its possible. It's for resizing purposes. Glide has a good image enhancement with scale. The problem is that I have resources as bitmap already loaded to memory. The only solution I could find is to store images to temporary file and reload them back to Glide as inputStream/file.. Is there a better way to achieve that ?

Please before answering .. Im not talking about output from Glide.. .asBitmap().get() I know that.I need help with input.

Here is my workaround solution:

 Bitmap bitmapNew=null;
        try {
            //
            ContextWrapper cw = new ContextWrapper(ctx);
            File directory = cw.getDir("imageDir", Context.MODE_PRIVATE);
            File file=new File(directory,"temp.jpg");
            FileOutputStream fos = new FileOutputStream(file);
            bitmap.compress(Bitmap.CompressFormat.PNG, 90, fos);
            fos.close();
            //
            bitmapNew = Glide
                    .with(ctx)
                    .load(file)
                    .asBitmap()
                    .diskCacheStrategy(DiskCacheStrategy.NONE)
                    .skipMemoryCache(true)
                    .into( mActualWidth, mActualHeight - heightText)
                    .get();

            file.delete();
        } catch (Exception e) {
            Logcat.e( "File not found: " + e.getMessage());
        }

I'd like to avoid writing images to internal and load them again.That is the reason why Im asking if there is way to to have input as bitmap

Thanks

Answer 1

For version 4 you have to call asBitmap() before load()

GlideApp.with(itemView.getContext())
        .asBitmap()
        .load(data.getImageUrl())
        .into(new SimpleTarget<Bitmap>() {
            @Override
            public void onResourceReady(Bitmap resource, Transition<? super Bitmap> transition) {}
            });
        }

More info: http://bumptech.github.io/glide/doc/targets.html

Answer 2

This solution is working with Glide V4. You can get the bitmap like this:

Bitmap bitmap = Glide
    .with(context)
    .asBitmap()
    .load(uri_File_String_Or_ResourceId)
    .submit()
    .get();

Note: this will block the current thread to load the image.

A really strange case, but lets try to solve it. I'm using the old and not cool Picasso , but one day I'll give Glide a try. Here are some links that could help you :

• Bitmap POC
• Supporting bitmaps topic
• Someone also facing your problem

And actually a cruel but I think efficient way to solve this :

ByteArrayOutputStream stream = new ByteArrayOutputStream();
  yourBitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
  Glide.with(this)
      .load(stream.toByteArray())
      .asBitmap()
      .error(R.drawable.ic_thumb_placeholder)
      .transform(new CircleTransform(this))
      .into(imageview);

I'm not sure if this will help you, but I hope it can make you a step closer to the solution.

Answer 4

There is little changes according to latest version of Glide . Now we need to use submit() to load image as bitmap, if you do not class submit() than listener won't be called.

here is working example i used today.

Glide.with(cxt)
  .asBitmap().load(imageUrl)
  .listener(new RequestListener<Bitmap>() {
      @Override
      public boolean onLoadFailed(@Nullable GlideException e, Object o, Target<Bitmap> target, boolean b) {
          Toast.makeText(cxt,getResources().getString(R.string.unexpected_error_occurred_try_again),Toast.LENGTH_SHORT).show();
          return false;
      }

      @Override
      public boolean onResourceReady(Bitmap bitmap, Object o, Target<Bitmap> target, DataSource dataSource, boolean b) {
          zoomImage.setImage(ImageSource.bitmap(bitmap));
          return false;
      }
  }
).submit();

It is working and I'm getting bitmap from listener.

Answer 5

Please use Implementation for that is:

implementation 'com.github.bumptech.glide:glide:4.9.0'

     Glide.with(this)
     .asBitmap()
      .load("http://url")
    .into(new CustomTarget <Bitmap>() {   
@Override  
public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition <? super Bitmap> transition) { 
                // you can do something with loaded bitmap here

 }
@Override 
public void onLoadCleared(@Nullable Drawable placeholder) { 
 } 
});

Answer 6

Most of the API's and methods of Glide are now deprecated. Below is working for Glide 4.9 and upto Android 10.

For image URI

  Bitmap bitmap = Glide
    .with(context)
    .asBitmap()
    .load(image_uri_or_drawable_resource_or_file_path)
    .submit()
    .get();

Use Glide as below in build.gradle

implementation 'com.github.bumptech.glide:glide:4.9.0'

Answer 7

The accepted answer works for previous versions, but in new versions of Glide use:

RequestOptions requestOptions = new RequestOptions();
requestOptions.placeholder(android.R.drawable.waiting);
requestOptions.error(R.drawable.waiting);
Glide.with(getActivity()).apply(requestOptions).load(imageUrl).into(imageView);

Answer 8

here's another solution which return you a bitmap to set into your ImageView

Glide.with(this)
            .load(R.drawable.card_front)    // you can pass url too
            .asBitmap()
            .into(new SimpleTarget<Bitmap>() {
                @Override
                public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) {
                    // you can do something with loaded bitmap here

                    imgView.setImageBitmap(resource);
                }
            });

Answer 9

This worked for me in recent version of Glide:

Glide.with(this)
        .load(bitmap)
        .dontTransform()
        .into(imageView);

Answer 10

For what is is worth, based upon the posts above, my approach:

     Uri sArtworkUri = Uri.parse("content://media/external/audio/albumart");
Uri imageUri = Uri.withAppendedPath(sArtworkUri, String.valueOf(album_id));

then in the adapter:

        //  loading album cover using Glide library

    Glide.with(mContext)
            .asBitmap()
            .load(imageUri)
            .into(holder.thumbnail);

In Kotlin,

Glide.with(this)
            .asBitmap()
            .load("https://...")
            .addListener(object : RequestListener<Bitmap> {
                override fun onLoadFailed(
                    e: GlideException?,
                    model: Any?,
                    target: Target<Bitmap>?,
                    isFirstResource: Boolean
                ): Boolean {
                    Toast.makeText(this@MainActivity, "failed: " + e?.printStackTrace(), Toast.LENGTH_SHORT).show()
                    return false
                }

                override fun onResourceReady(
                    resource: Bitmap?,
                    model: Any?,
                    target: Target<Bitmap>?,
                    dataSource: DataSource?,
                    isFirstResource: Boolean
                ): Boolean {
                    //image is ready, you can get bitmap here
                    return false
                }

            })
            .into(imageView)

Updated answer 2021 Aug

Glide.with(context)
      .asBitmap()
      .load(uri)
      .into(new CustomTarget<Bitmap>() {
          @Override
          public void onResourceReady(@NonNull Bitmap resource, Transition<? super Bitmap> transition) {
              useIt(resource);
          }

          @Override
          public void onLoadCleared(@Nullable Drawable placeholder) {
          }
      });

onResourceReady : The method that will be called when the resource load has finished.
resource parameter is the loaded resource.

onLoadCleared : A mandatory lifecycle callback that is called when a load is cancelled and its resources are freed. You must ensure that any current Drawable received in onResourceReady is no longer used before redrawing the container (usually a View) or changing its visibility.
placeholder parameter is the placeholder drawable to optionally show, or null.
