GlideImage

You can load images simply by using GlideImage composable function as the following example below:

GlideImage(
  imageModel = imageUrl,
  // Crop, Fit, Inside, FillHeight, FillWidth, None
  contentScale = ContentScale.Crop,
  // shows a placeholder while loading the image.
  placeHolder = ImageBitmap.imageResource(R.drawable.placeholder),
  // shows an error ImageBitmap when the request failed.
  error = ImageBitmap.imageResource(R.drawable.error)
)

Custom RequestOptions and TransitionOptions

You can customize your request-options with your own RequestOptions and TransitionOptions for applying caching strategies, loading transformations like below:

GlideImage(
  imageModel = poster.poster,
  requestOptions = {
    RequestOptions()
        .override(256, 256)
        .diskCacheStrategy(DiskCacheStrategy.ALL)
        .centerCrop()
  },
  contentScale = ContentScale.Crop,
  modifier = modifier,
  alignment = Alignment.Center,
)

Custom RequestBuilder

You can request image with your own RequestBuilder, which is the backbone of the request in Glide and is responsible for bringing your options together with your requested url or model to start a new load.

GlideImage(
  imageModel = poster.poster,
  requestBuilder = { Glide.with(LocalContext.current.applicationContext).asDrawable() },
  modifier = Modifier.constrainAs(image) {
    centerHorizontallyTo(parent)
    top.linkTo(parent.top)
  }.aspectRatio(0.8f)
)

Custom RequestListener

You can register your own RequestListener, which allows you to trace the status of a request while images load.

GlideImage(
  imageModel = poster.poster,
  requestListener = object: RequestListener<Drawable> {
    override fun onLoadFailed(
      e: GlideException?,
      model: Any?,
      target: Target<Drawable>?,
      isFirstResource: Boolean
    ): Boolean {
      // do something
      return false
    }

    override fun onResourceReady(
    resource: Drawable?,
      model: Any?,
      target: Target<Drawable>?,
      dataSource: DataSource?,
      isFirstResource: Boolean
    ): Boolean {
      // do something
      return true
    }
  }
)

LocalGlideRequestOptions

You can pass the same instance of your RequestOptions down through the Composition in your composable hierarchy as following the example below:

val requestOptions = RequestOptions()
    .override(300, 300)
    .circleCrop()

CompositionLocalProvider(LocalGlideRequestOptions provides requestOptions) {
  // Loads images with the custom `requestOptions` without explicit defines.
  GlideImage(
    imageModel = ...
  )
}

Coil

Add the dependency below to your module's build.gradle file:

dependencies {
    implementation "com.github.skydoves:landscapist-coil:<version>"
}

Note: Please make sure your project uses the same Jetpack Compose version on the release page.

CoilImage

You can load images by using the CoilImage composable function as the following example below:

CoilImage(
  imageModel = imageUrl,
  // Crop, Fit, Inside, FillHeight, FillWidth, None
  contentScale = ContentScale.Crop,
  // shows a placeholder while loading the image.
  placeHolder = ImageBitmap.imageResource(R.drawable.placeholder),
  // shows an error ImageBitmap when the request failed.
  error = ImageBitmap.imageResource(R.drawable.error)
)

Custom ImageRequest and ImageLoader

You can load images with your own ImageRequest and ImageLoader, which provides all the necessary information for loading images like caching strategies and transformations.

CoilImage(
  imageRequest = {
      ImageRequest.Builder(LocalContext.current)
        .data(poster.poster)
        .crossfade(true)
        .build() },
  imageLoader = {
      ImageLoader.Builder(LocalContext.current)
        .availableMemoryPercentage(0.25)
        .crossfade(true)
        .build() },
  contentScale = ContentScale.Crop,
  modifier = modifier,
  alignment = Alignment.Center,
)

LocalCoilImageLoader

You can pass the same instance of your ImageLoader down through the Composition in your composable hierarchy as following the example below:

val imageLoader = ImageLoader.Builder(context).build()
CompositionLocalProvider(LocalCoilImageLoader provides imageLoader) {
  // This will automatically use the value of current imageLoader in the hierarchy.
  CoilImage(
    imageModel = ...
  )
}

Animated Image Supports (GIF, Webp)

You can load animated GIFs and WebP Images with your ImageLoader.

val context = LocalContext.current
val imageLoader = ImageLoader.Builder(context)
  .componentRegistry {
    if (SDK_INT >= 28) {
      add(ImageDecoderDecoder(context))
    } else {
      add(GifDecoder())
    }
  }
  .build()

CoilImage(
    imageModel = poster.gif, // URL of an animated image.
    imageLoader = { imageLoader },
    shimmerParams = ShimmerParams(
      baseColor = background800,
      highlightColor = shimmerHighLight
    ),
    modifier = Modifier
      .fillMaxWidth()
      .padding(8.dp)
      .height(500.dp)
      .clip(RoundedCornerShape(8.dp))
  )

Fresco

Add the dependency below to your module's build.gradle file:

dependencies {
    implementation "com.github.skydoves:landscapist-fresco:<version>"
}

Note: Landscapist-Fresco includes version 2.6.0 of Fresco. So please make sure your project is using the same Fresco version or exclude the Fresco dependency to adapt yours. Also, please make sure the Jetpack Compose version on the release page.

Setup

To get started, you should set up Fresco with ImagePipelineConfig in your Application class. Generally, it's recommended initializing with OkHttpImagePipelineConfigFactory. Also, you can customize caching, networking, and thread pool strategies with your own ImagePipelineConfig. For more details, you can check out Using Other Network Layers.

class App : Application() {

  override fun onCreate() {
    super.onCreate()

    val pipelineConfig =
      OkHttpImagePipelineConfigFactory
        .newBuilder(this, OkHttpClient.Builder().build())
        .setDiskCacheEnabled(true)
        .setDownsampleEnabled(true)
        .setResizeAndRotateEnabledForNetwork(true)
        .build()

    Fresco.initialize(this, pipelineConfig)
  }
}

FrescoImage

You can load images by using the FrescoImage composable function as the following example below:

FrescoImage(
  imageUrl = stringImageUrl,
  // Crop, Fit, Inside, FillHeight, FillWidth, None
  contentScale = ContentScale.Crop,
  // shows a placeholder while loading the image.
  placeHolder = ImageBitmap.imageResource(R.drawable.placeholder),
  // shows an error ImageBitmap when the request failed.
  error = ImageBitmap.imageResource(R.drawable.error)
)

Custom ImageRequest

You can load images with your own ImageRequest, which provides some necessary information for loading images like decoding strategies and resizing.

val imageRequest = ImageRequestBuilder
  .newBuilderWithSource(uri)
  .setImageDecodeOptions(decodeOptions)
  .setLocalThumbnailPreviewsEnabled(true)
  .setLowestPermittedRequestLevel(RequestLevel.FULL_FETCH)
  .setProgressiveRenderingEnabled(false)
  .setResizeOptions(ResizeOptions(width, height))
  .build()

FrescoImage(
  imageUrl = stringImageUrl,
  imageRequest = { imageRequest },
  contentScale = ContentScale.Crop)

LocalFrescoImageRequest

You can pass the same instance of your ImageRequest down through the Composition in your composable hierarchy as following the example below:

// customize the ImageRequest as needed
val imageRequest = ImageRequestBuilder
  .newBuilderWithSource(uri)
  .setImageDecodeOptions(decodeOptions)
  .setLocalThumbnailPreviewsEnabled(true)
  .setLowestPermittedRequestLevel(RequestLevel.FULL_FETCH)
  .setProgressiveRenderingEnabled(false)
  .setResizeOptions(ResizeOptions(width, height))
  .build()

CompositionLocalProvider(LocalFrescoImageRequest provides imageRequest) {
  // This will automatically use the value of current ImageRequest in the hierarchy.
  FrescoImage(
    imageurl = ...
  )
}

Fresco Animated Image Support (GIF, Webp)

Add the below dependency to your module's build.gradle file.

dependencies {
  implementation "com.github.skydoves:landscapist-fresco-websupport:<version>"
}

You can load animated GIFs and WebP Images with FrescoWebImage composable function. You should pass the AbstractDraweeController like the following example below:

FrescoWebImage(
  controllerBuilder = Fresco.newDraweeControllerBuilder()
    .setUri(poster.gif) // GIF or Webp image url.
    .setAutoPlayAnimations(true),
  modifier = Modifier
    .fillMaxWidth()
    .height(300.dp)
)

For more details, check out DraweeController, and Supported URIs for setting URI addresses. Also, you can load general images (jpeg, png, etc) which can be loaded with FrescoImage by using FrescoWebImage and your custom controller.

Custom Composables

You can execute your own composable functions depending on the three request states below:

loading: Executed when loading an image.
success: Executed when successful to load an image.
failure: Executed when failing to load an image (e.g. network error, wrong destination).

 GlideImage( // CoilImage, FrescoImage
   imageModel = imageUrl,
   modifier = modifier,
   // shows an indicator while loading an image.
   loading = {
     Box(modifier = Modifier.matchParentSize()) {
        CircularProgressIndicator(
          modifier = Modifier.align(Alignment.Center)
        )
     }
   },
   // shows an error text if fail to load an image.
   failure = {
     Text(text = "image request failed.")
   })

Also, you can customize the image content with our own composable function like the example below:

GlideImage( // CoilImage, FrescoImage
  imageModel = imageUrl,
  // draw a resized image.
  success = { imageState ->
    imageState.imageBitmap?.let {
      Image(
        bitmap = it,
        modifier = Modifier.size(128.dp)
      )
    }
  },
  loading = { 
    // do something 
  })

Note: You can also use the custom Composables for CoilImage and FrescoImage.

Preview on Android Studio

Landscapist supports preview mode for each image library; Glide, Coil, and Fresco. You can show the preview image on your editor with a previewPlaceholder parameter as following:

GlideImage(
  imageModel = poster.poster,
  modifier = Modifier.aspectRatio(0.8f),
  previewPlaceholder = R.drawable.poster
)

Note: You can also use the the previewPlaceholder parameter for CoilImage and FrescoImage.

Shimmer Effect

You can implement a shimmering effect while loading an image by using the ShimmerParams parameter as following the example below:

GlideImage( // CoilImage, FrescoImage
   imageModel = imageUrl,
   modifier = modifier,
   // shows a shimmering effect when loading an image.
   shimmerParams = ShimmerParams(
       baseColor = MaterialTheme.colors.background,
       highlightColor = shimmerHighLight,
       durationMillis = 350,
       dropOff = 0.65f,
       tilt = 20f
     ),
   // shows an error text message when request failed.
   failure = {
     Text(text = "image request failed.")
   })

Note: You can also use the Shimmer effect for CoilImage and FrescoImage.

Circular Reveal Animation

You can implement the circular reveal animation while drawing images with CircularReveal attribute as the following:

GlideImage( // CoilImage, FrescoImage
  imageModel = imageUrl,
  // Crop, Fit, Inside, FillHeight, FillWidth, None
  contentScale = ContentScale.Crop,
  // shows an image with the circular reveal animation.
  circularReveal = CircularReveal(duration = 350),
  // shows a placeholder ImageBitmap when loading.
  placeHolder = ImageBitmap.imageResource(R.drawable.placeholder),
  // shows an error ImageBitmap when the request failed.
  error = ImageBitmap.imageResource(R.drawable.error)
)

The default value of the circularReveal is null.

Note: You can also use the Circular Reveal Animation for CoilImage and FrescoImage.

Palette

You can extract primary (theme) color profiles with BitmapPalette. You can check out Extract color profiles to see what kinds of colors can be extracted.

var palette by remember { mutableStateOf<Palette?>(null) }

GlideImage( // CoilImage, FrescoImage also can be used.
  imageModel = imageUrl,
  bitmapPalette = BitmapPalette {
    palette = it
  }
)

Crossfade(
  targetState = palette,
  modifier = Modifier
    .padding(horizontal = 8.dp)
    .size(45.dp)
) {
  Box(
    modifier = Modifier
      .background(color = Color(it?.lightVibrantSwatch?.rgb ?: 0))
      .fillMaxSize()
  )
}

Also, you can customize attributes of BitmapPalette like the example below:

var palette by remember { mutableStateOf<Palette?>(null) }

GlideImage( // CoilImage, FrescoImage also can be used.
  imageModel = imageUrl,
  modifier = Modifier
    .aspectRatio(0.8f),
  bitmapPalette = BitmapPalette(
    imageModel = poster.poster,
    useCache = true,
    interceptor = {
      it.addFilter { rgb, hsl ->
        // here edit to add the filter colors.
        false
      }
    },
    paletteLoadedListener = {
      palette = it
    }
  )
)

Note: You can also use the Palette for CoilImage and FrescoImage.

Inspiration

This library was mostly inspired by Accompanist.

Accompanist is a group of libraries that contains some utilities which I've found myself copying around projects which use Jetpack Compose. Currently, it contains image loading and insets. You can get more variety and recent systems from the library maintained by Google.
