## Glide

## Introduction:
Glide is a fast and efficient image loading library for openharmony focused on smooth scrolling. Glide offers an easy to use API, a performant and extensible resource decoding pipeline and automatic resource pooling.# Glide

Glide hmos testapplication + ported code project
Glide supports fetching, decoding, and displaying video stills, images, and animated GIFs. Glide includes a flexible api that allows developers to plug in to almost any network stack. By default Glide uses a custom HttpUrlConnection based stack, but also includes utility libraries plug in to Google's Volley project or Square's OkHttp library instead.

Glide primary focus is on making scrolling any kind of a list of images as smooth and fast as possible, but Glide is also effective for almost any case where you need to fetch, resize, and display a remote image.

## Usage Instructions:
API
Glide uses a simple fluent API that allows users to make most requests in a single line:

```
1)Load Image from Internet
 //String can be like "https://picsum.photos/600"
 Glide.with(classcontext)
                    .load(String)  
                    .diskCacheStrategy(DiskCacheStrategy.NONE)
                    .skipMemoryCache(true)
                    .into(imageView);
                    
2)Load Image from Resource Folder
    //ResourceId can be esourceTable.Media_penguins
    Glide.with(classcontext)
            .load(ResourceId) 
            .diskCacheStrategy(DiskCacheStrategy.NONE)
            .skipMemoryCache(true)
            .into(imageView);
            
3) Uri uri =Uri.parse("https://picsum.photos/600");
   Glide.with(classcontext)
        .load(uri)
        .diskCacheStrategy(DiskCacheStrategy.NONE)
        .skipMemoryCache(true)
        .into(imageView);

4)Uri uri =Uri.parse("dataability:///" + "com.bumptech.glide"+ "/" + ResourceTable.Media_jellyfish);
  Glide.with(classcontext)
        .load(uri)
        .diskCacheStrategy(DiskCacheStrategy.NONE)
        .skipMemoryCache(true)
        .into(imageView);
```
## GIF Introduction:
1. How to load a GIF by "Glide"

a. load gif from network
```
    DraweeView image = (DraweeView) findComponentById(ResourceTable.Id_image);
    Glide.with(this)
         .asGif()
         .load("https://img.blog.csdnimg.cn/2019120901303086.gif);
         .into(image);
```

b. load gif from native.
```
         DraweeView image = (DraweeView) findComponentById(ResourceTable.Id_drawview);
            Glide.with(this)
                 .asGif()
                 .load(ResourceTable.Media_happygirl);
                 .into(draweeView);  
``` 
             
2. Lifecycle Management, the context is not an AbilitySlice or Ability object.

The context is not an AbilitySlice or Ability object. After the GIF does not need to work, manually invoke the stopGif() method of the DraweeView to stop the Glide to prevent resource waste.
 ```
    DraweeView draweeView;
    @Override
    protected void onStart(Intent intent) {
        super.onStart(intent);
        super.setUIContent(ResourceTable.Layout_dodo1_slice_layout);
        draweeView = (DraweeView) findComponentById(ResourceTable.Id_draweeView);
        Glide.with(getApplicationContext())
           .asGif()
           .load(ResourceTable.Media_happygirl);
           .into(draweeView); 
        
    }

@Override
    protected void onBackground() {
        super.onBackground();
        draweeView.stopGif();
    }
```

3. setScaleType Function

a. support Scale Mode

```
    public static enum ScaleMode {
        ZOOM_CENTER,
        ZOOM_START,
        ZOOM_END,
        STRECH,
        CENTER,
        INSIDE,
        CLIP_CENTER;
    }
```

b. how to use

```
    draweeView.setScaleType(mode);
```

4. Important Note:

1. Currently the DrawView must be used to use the GIF. You can also onherit the customized implementation.
    2. If a context with a long lifecycle of a Glide is used, for example, applicationContext, call the stopGif method of the DraweeView when the GIF page ends to stop the Glide to reduceresource waste.
    3. You are advised to use the Ability object or Ability Slice object as the lifecycele of the Glide. In this way the Glide can help yourelease resources in a timely manner.
    4. Currently, the getContext() method for generating weight in xml format cannot be used as the Glide context input parameter. There is a problem that the context of weight is the context of the first AbilitySlice page,
        not the context of the current Ability Slice page. this has uncertain consequences, very serious. It is recommeneded that you use the Ability Object or the AbilitySlice Object as the context of the Glide.

## Installation instructions:

```
Method 1:
    Generate the .har package through the library and add the .har package to the libs folder.
    Add the following code to the entry gradle:
        implementation fileTree  (dir: 'libs', include: ['*.jar', '*.har'])

Method 2:
    allprojects{
        repositories{
            mavenCentral()
        }
    }
implementation 'io.openharmony.tpc.thirdlib:glide:1.0.6'
