|Modifier and Type||Method and Description|
A method to get a unique identifier for this particular transformation that can be used as part of a cache key.
Transforms the given resource and returns the transformed resource.
public Resource<GifDrawable> transform(Resource<GifDrawable> resource, int outWidth, int outHeight)
Note - If the original resource object is not returned, the original resource will be recycled and it's internal resources may be reused. This means it is not safe to rely on the original resource or any internal state of the original resource in any new resource that is created. Usually this shouldn't occur, but if absolutely necessary either the original resource object can be returned with modified internal state, or the data in the original resource can be copied into the transformed resource.
resource- The resource to transform.
outWidth- The width of the view or target the resource will be displayed in, or
Target.SIZE_ORIGINALto indicate the original resource width.
outHeight- The height of the view or target the resource will be displayed in, or
Target.SIZE_ORIGINALto indicate the original resource height.
public String getId()
If this transformation does not affect the data that will be stored in cache, returning an empty string here is acceptable.
