Glide: Transformation not applied onto SVG

[sebastianmarschall]

I'm loading a raw SVG like shown in the sample project.
Problem is: applying a transformation onto a SVG has no effect.
See https://github.com/sebastianmarschall/GlideSvgTransformation as example.

Glide Version: 4.7.1

Integration libraries:

Caverock AndroidSvg Version: 1.2.1

Device/Android Version: Nexus 6p, Samsung S7, Samsung S9

Issue details / Repro steps / Use case background:
See the example project linked above. For example applying the "centerCrop()" transformation has no effect. My guess is that its because the Transformation is a BitmapTransformation and the loaded SVG is a PictureDrawable, but i have no idea how to work around this issue.

Glide load line / GlideModule (if any) / list Adapter code (if any):

requestBuilder = Glide.with(this)
        .`as`(PictureDrawable::class.java)
        .apply(RequestOptions().circleCrop())
        .listener(SvgSoftwareLayerSetter())

val uri = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" + packageName + "/" + R.raw.android_toy_h)
requestBuilder.load(uri).into(imageView)

Layout XML:

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    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="200dp"
        android:layout_height="125dp"
        android:transitionName="svgTransition"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</android.support.constraint.ConstraintLayout>

You could write a transformation that acts on the SVG directly and apply it with transform(): http://bumptech.github.io/glide/javadocs/470/com/bumptech/glide/request/RequestOptions.html#transform-java.lang.Class-com.bumptech.glide.load.Transformation-.

Alternatively you could modify the ResourceDecoder you're using to decode the PictureDrawable to instead draw the PictureDrawable to a Bitmap. Then normal Bitmap transformations will work as well.

can you please be more clear about how to do this " You could write a transformation that acts on the SVG directly and apply it with Transform()"

I need the same details to resolve this issue.
I don't know what is the point of this Stale bot which marks issues as Stale since this is not resolved and needs attention.
