Downloading a URL into an ImageView is very easy using Glide:
Glide
.with(context)
.load(getIntent().getData())
.placeholder(R.drawable.ic_loading)
.centerCrop()
.into(imageView);
I'm wondering if I can download into a Bitmap as well? I'd like to download into a raw bitmap that I can then manipulate using other tools. I've been through the code and don't see how to do it.
Make sure you are on the Lastest version
implementation 'com.github.bumptech.glide:glide:4.10.0'
Kotlin:
Glide.with(this)
.asBitmap()
.load(imagePath)
.into(object : CustomTarget<Bitmap>(){
override fun onResourceReady(resource: Bitmap, transition: Transition<in Bitmap>?) {
imageView.setImageBitmap(resource)
}
override fun onLoadCleared(placeholder: Drawable?) {
// this is called when imageView is cleared on lifecycle call or for
// some other reason.
// if you are referencing the bitmap somewhere else too other than this imageView
// clear it here as you can no longer have the bitmap
}
})
Bitmap Size:
if you want to use the original size of the image use the default constructor as above, else You can pass your desired size for bitmap
into(object : CustomTarget<Bitmap>(1980, 1080)
Java:
Glide.with(this)
.asBitmap()
.load(path)
.into(new CustomTarget<Bitmap>() {
@Override
public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {
imageView.setImageBitmap(resource);
}
@Override
public void onLoadCleared(@Nullable Drawable placeholder) {
}
});
Old Answer:
With compile 'com.github.bumptech.glide:glide:4.8.0' and below
Glide.with(this)
.asBitmap()
.load(path)
.into(new SimpleTarget<Bitmap>() {
@Override
public void onResourceReady(Bitmap resource, Transition<? super Bitmap> transition) {
imageView.setImageBitmap(resource);
}
});
For compile 'com.github.bumptech.glide:glide:3.7.0' and below
Glide.with(this)
.load(path)
.asBitmap()
.into(new SimpleTarget<Bitmap>() {
@Override
public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) {
imageView.setImageBitmap(resource);
}
});
Now you might see a warning SimpleTarget is deprecated
Reason:
The main point of deprecating SimpleTarget is to warn you about the ways in which it tempts you to break Glide's API contract. Specifically, it doesn't do anything to force you to stop using any resource you've loaded once the SimpleTarget is cleared, which can lead to crashes and graphical corruption.
The SimpleTarget still can be used as long you make sure you are not using the bitmap once the imageView is cleared.
4.9.0 –
Malliemallin .asBitmap() should be put after with(this) if it's unresolved. –
Maxson Glide.with(application).asBitmap().load(pictureUrl).circleCrop().submit().get() works fine for notification icon also in addition to @Musso suggestion –
Urn I'm not familiar enough with Glide, but it looks like if you know the target size, you can use something like this:
Bitmap theBitmap = Glide.
with(this).
load("http://....").
asBitmap().
into(100, 100). // Width and height
get();
It looks like you can pass -1,-1, and get a full size image (purely based on tests, can't see it documented).
Note into(int,int) returns a FutureTarget<Bitmap>, so you have to wrap this in a try-catch block covering ExecutionException and InterruptedException. Here's a more complete example implementation, tested and working:
class SomeActivity extends Activity {
private Bitmap theBitmap = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
// onCreate stuff ...
final ImageView image = (ImageView) findViewById(R.id.imageView);
new AsyncTask<Void, Void, Void>() {
@Override
protected Void doInBackground(Void... params) {
Looper.prepare();
try {
theBitmap = Glide.
with(SomeActivity.this).
load("https://www.google.es/images/srpr/logo11w.png").
asBitmap().
into(-1,-1).
get();
} catch (final ExecutionException e) {
Log.e(TAG, e.getMessage());
} catch (final InterruptedException e) {
Log.e(TAG, e.getMessage());
}
return null;
}
@Override
protected void onPostExecute(Void dummy) {
if (null != theBitmap) {
// The full bitmap should be available here
image.setImageBitmap(theBitmap);
Log.d(TAG, "Image loaded");
};
}
}.execute();
}
}
Following Monkeyless' suggestion in the comment below (and this appears to be the official way too), you can use a SimpleTarget, optionally coupled with override(int,int) to simplify the code considerably. However, in this case the exact size must be provided (anything below 1 isn't accepted):
Glide
.with(getApplicationContext())
.load("https://www.google.es/images/srpr/logo11w.png")
.asBitmap()
.into(new SimpleTarget<Bitmap>(100,100) {
@Override
public void onResourceReady(Bitmap resource, GlideAnimation glideAnimation) {
image.setImageBitmap(resource); // Possibly runOnUiThread()
}
});
as suggested by @hennry if you required the same image then use new SimpleTarget<Bitmap>()
UPDATE
bitmap = Glide.with(c).asBitmap().load( "url").submit().get();
into(-1,-1) appears to work to get the full size image, I'd try that too. –
Petrozavodsk Target.SIZE_ORIGINAL for both width and height of bitmap instead of -1 –
Lampley SimpleTarget like this : new SimpleTarget<Bitmap>(){....} –
Idiocrasy It looks like overriding the Target class or one of the implementations like BitmapImageViewTarget and overriding the setResource method to capture the bitmap might be the way to go...
This is untested. :-)
Glide.with(context)
.load("http://goo.gl/h8qOq7")
.asBitmap()
.into(new BitmapImageViewTarget(imageView) {
@Override
protected void setResource(Bitmap resource) {
// Do bitmap magic here
super.setResource(resource);
}
});
UPDATE
Now we need to use Custom Targets
SAMPLE CODE
Glide.with(mContext)
.asBitmap()
.load("url")
.into(new CustomTarget<Bitmap>() {
@Override
public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {
}
@Override
public void onLoadCleared(@Nullable Drawable placeholder) {
}
});
How does one use glide to download an image into a bitmap?
The above all answer are correct but outdated
because in new version of Glide implementation 'com.github.bumptech.glide:glide:4.8.0'
You will find below error in code
.asBitmap() is not available in glide:4.8.0
SimpleTarget<Bitmap>
Here is solution
import android.graphics.Bitmap;
import android.graphics.Canvas;
import android.graphics.drawable.BitmapDrawable;
import android.graphics.drawable.Drawable;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.ImageView;
import com.bumptech.glide.Glide;
import com.bumptech.glide.load.engine.DiskCacheStrategy;
import com.bumptech.glide.request.Request;
import com.bumptech.glide.request.RequestOptions;
import com.bumptech.glide.request.target.SizeReadyCallback;
import com.bumptech.glide.request.target.Target;
import com.bumptech.glide.request.transition.Transition;
public class MainActivity extends AppCompatActivity {
ImageView imageView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imageView = findViewById(R.id.imageView);
Glide.with(this)
.load("")
.apply(new RequestOptions().diskCacheStrategy(DiskCacheStrategy.NONE))
.into(new Target<Drawable>() {
@Override
public void onLoadStarted(@Nullable Drawable placeholder) {
}
@Override
public void onLoadFailed(@Nullable Drawable errorDrawable) {
}
@Override
public void onResourceReady(@NonNull Drawable resource, @Nullable Transition<? super Drawable> transition) {
Bitmap bitmap = drawableToBitmap(resource);
imageView.setImageBitmap(bitmap);
// now you can use bitmap as per your requirement
}
@Override
public void onLoadCleared(@Nullable Drawable placeholder) {
}
@Override
public void getSize(@NonNull SizeReadyCallback cb) {
}
@Override
public void removeCallback(@NonNull SizeReadyCallback cb) {
}
@Override
public void setRequest(@Nullable Request request) {
}
@Nullable
@Override
public Request getRequest() {
return null;
}
@Override
public void onStart() {
}
@Override
public void onStop() {
}
@Override
public void onDestroy() {
}
});
}
public static Bitmap drawableToBitmap(Drawable drawable) {
if (drawable instanceof BitmapDrawable) {
return ((BitmapDrawable) drawable).getBitmap();
}
int width = drawable.getIntrinsicWidth();
width = width > 0 ? width : 1;
int height = drawable.getIntrinsicHeight();
height = height > 0 ? height : 1;
Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
drawable.draw(canvas);
return bitmap;
}
}
This is what worked for me: https://github.com/bumptech/glide/wiki/Custom-targets#overriding-default-behavior
import com.bumptech.glide.Glide;
import com.bumptech.glide.request.transition.Transition;
import com.bumptech.glide.request.target.BitmapImageViewTarget;
...
Glide.with(yourFragment)
.load("yourUrl")
.asBitmap()
.into(new BitmapImageViewTarget(yourImageView) {
@Override
public void onResourceReady(Bitmap bitmap, Transition<? super Bitmap> anim) {
super.onResourceReady(bitmap, anim);
Palette.generateAsync(bitmap, new Palette.PaletteAsyncListener() {
@Override
public void onGenerated(Palette palette) {
// Here's your generated palette
Palette.Swatch swatch = palette.getDarkVibrantSwatch();
int color = palette.getDarkVibrantColor(swatch.getTitleTextColor());
}
});
}
});
If you want to assign dynamic bitmap image to bitmap variables
Example for kotlin
backgroundImage = Glide.with(applicationContext).asBitmap().load(PresignedUrl().getUrl(items!![position].img)).submit(100, 100).get();
The above answers did not work for me
.asBitmap should be before the .load("http://....")
UPDATE FOR NEW VERSION
Glide.with(context.applicationContext)
.load(url)
.listener(object : RequestListener<Drawable> {
override fun onLoadFailed(
e: GlideException?,
model: Any?,
target: Target<Drawable>?,
isFirstResource: Boolean
): Boolean {
listener?.onLoadFailed(e)
return false
}
override fun onResourceReady(
resource: Drawable?,
model: Any?,
target: com.bumptech.glide.request.target.Target<Drawable>?,
dataSource: DataSource?,
isFirstResource: Boolean
): Boolean {
listener?.onLoadSuccess(resource)
return false
}
})
.into(this)
OLD ANSWER
@outlyer's answer is correct, but there're some changes in new Glide version
My version: 4.7.1
Code:
Glide.with(context.applicationContext)
.asBitmap()
.load(iconUrl)
.into(object : SimpleTarget<Bitmap>(Target.SIZE_ORIGINAL, Target.SIZE_ORIGINAL) {
override fun onResourceReady(resource: Bitmap, transition: com.bumptech.glide.request.transition.Transition<in Bitmap>?) {
callback.onReady(createMarkerIcon(resource, iconId))
}
})
Note: this code run in UI Thread, thus you can use AsyncTask, Executor or somethings else for concurrency (like @outlyer's code) If you want to get original size, put Target.SIZE_ORIGINA as my code. Don't use -1, -1
for Glide version 4.10.0: Glide.with(context).download(mImageUrl).submit().get()
Kotlin Function
inline fun getBitmap(imageUrl: String, block: (Bitmap?) -> Unit) {
return try {
val url = URL(imageUrl)
val image = BitmapFactory.decodeStream(url.openConnection().getInputStream())
block(image)
} catch (e: IOException) {
println(e)
block(null)
}
}
Newer version:
GlideApp.with(imageView)
.asBitmap()
.override(200, 200)
.centerCrop()
.load(mUrl)
.error(R.drawable.defaultavatar)
.diskCacheStrategy(DiskCacheStrategy.ALL)
.signature(ObjectKey(System.currentTimeMillis() / (1000*60*60*24))) //refresh avatar cache every day
.into(object : CustomTarget<Bitmap>(){
override fun onLoadCleared(placeholder: Drawable?) {}
override fun onLoadFailed(errorDrawable: Drawable?) {
//add context null check in case the user left the fragment when the callback returns
context?.let { imageView.addImage(BitmapFactory.decodeResource(resources, R.drawable.defaultavatar)) }
}
override fun onResourceReady(
resource: Bitmap,
transition: Transition<in Bitmap>?) { context?.let { imageView.addImage(resource) } }
})
Kotlin's way -
fun Context.bitMapFromImgUrl(imageUrl: String, callBack: (bitMap: Bitmap) -> Unit) {
GlideApp.with(this)
.asBitmap()
.load(imageUrl)
.into(object : CustomTarget<Bitmap>() {
override fun onResourceReady(resource: Bitmap, transition: Transition<in Bitmap>?) {
callBack(resource)
}
override fun onLoadCleared(placeholder: Drawable?) {
// this is called when imageView is cleared on lifecycle call or for
// some other reason.
// if you are referencing the bitmap somewhere else too other than this imageView
// clear it here as you can no longer have the bitmap
}
})
}
in kotlin you can use
CoroutineScope(Dispatchers.IO).launch {
Glide.with(this@&YourActivity).asBitmap().load(imageUrl)
.listener(object : RequestListener<Bitmap> {
override fun onLoadFailed(
e: GlideException?,
model: Any?,
target: Target<Bitmap>?,
isFirstResource: Boolean
): Boolean {
Log.e("GlideException" ,"${e.message}")
return false
}
override fun onResourceReady(
resource: Bitmap?,
model: Any?,
target: Target<Bitmap>?,
dataSource: DataSource?,
isFirstResource: Boolean
): Boolean {
resource?.let {bitmap->
//here your bitmap is ready you can use it
}
return false
}
})
.submit().get()//by using this line glide lib behave as synchronously(block instructions until the task is completed) and by removing this line you can use it as a asynchronously(without blocking other operations)
}
I am using
api 'com.github.bumptech.glide:glide:4.12.0'
kapt 'com.github.bumptech.glide:compiler:4.12.0'
I had to add a try-catch block because now Glide Crashes the app if the URL is invalid.
return try {
Glide.with(context)
.asBitmap()
.load(imageURL)
.listener(object : RequestListener<Bitmap> {
override fun onLoadFailed(
e: GlideException?,
model: Any?,
target: Target<Bitmap>?,
isFirstResource: Boolean
): Boolean {
Log.e(
TAG,
"Texture from ResourceID $resourceId could not be Loaded. " +
"Using default Texture"
)
return false
}
override fun onResourceReady(
resource: Bitmap?,
model: Any?,
target: Target<Bitmap>?,
dataSource: DataSource?,
isFirstResource: Boolean
): Boolean {
return false
}
})
.placeholder(DEFAULT_IMAGE)
.error(DEFAULT_IMAGE)
.submit()
.get()
} catch (ex: Exception) {
return fromResource(DEFAULT_IMAGE)
}
This example Glide to download an image into a bitmap.
Step 1 - Add the following dependency in build.gradle: Module: app
implementation 'com.github.bumptech.glide:glide:4.9.0'
Step 2 − Add the following code to res/layout/activity_main.xml.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<ImageView
android:id="@+id/imageView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
Step 3 − Add the following code to src/MainActivity.java
import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.appcompat.app.AppCompatActivity;
import android.graphics.Bitmap;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.widget.ImageView;
import com.bumptech.glide.Glide;
import com.bumptech.glide.request.target.CustomTarget;
import com.bumptech.glide.request.transition.Transition;
public class MainActivity extends AppCompatActivity {
ImageView imageView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imageView = findViewById(R.id.imageView);
Glide.with(this).asBitmap().load("https://www.google.es/images/srpr/logo11w.png").into(new CustomTarget<Bitmap>() {
@Override
public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {
imageView.setImageBitmap(resource);
}
@Override
public void onLoadCleared(@Nullable Drawable placeholder) {
}
});
}
}
Step 4 − Add the following code to androidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="app.com.sample">
<uses-permission android:name="android.permission.INTERNET"/>
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Let's try to run your application.
In the latest version of Glide, we can do this
val bitmap = Glide.with(context)
.asBitmap()
.load("url")
.submit()
.get()
