+# Using as a Custom Drawable
+The library also provide custom drawable implementation in form of `VecotrMasterDrawable`. It provides the same control over the vector, but allows the user to use the drawable as per its wish, for e.g. as a `Compound Drawable` in `TextView`, or as the source drawable in `ImageView`; basically any use case that involves a `Drawable` can be replaced by `VectorMasterDrawable`.
+
+## Example
+#### XML
+```xml
+<TextView
+    android:id="@+id/text_view"
+    android:layout_width="wrap_content"
+    android:layout_height="wrap_content"
+    android:text="Heart"
+    android:textSize="30sp" />
+
+<ImageView
+    android:id="@+id/image_view"
+    android:layout_width="75dp"
+    android:layout_height="75dp"/>
+```
+
+#### Java
+```java
+// Instantiate the custom drawable
+VectorMasterDrawable vectorMasterDrawable = new VectorMasterDrawable(this, R.drawable.ic_heart);
+
+// Set top drawable for TextView
+TextView textView = (TextView) findViewById(R.id.text_view);
+textView.setCompoundDrawablesWithIntrinsicBounds(null, vectorMasterDrawable, null, null);
+
+// Set background drawable for ImageView
+ImageView imageView = (ImageView) findViewById(R.id.image_view);
+imageView.setImageDrawable(vectorMasterDrawable);
+
+// Set tht stroke color of the drawable
+PathModel pathModel = vectorMasterDrawable.getPathModelByName("outline");
+pathModel.setStrokeColor(Color.parseColor("#ED4337"));
+```

 # Limitations
 1. The `PathParser.java` has been extracted from Android source code of version 5.1.1. After this version all the parsing code was shifted to native for efficiency. I have incorporated some of the changes from the native code into the `PathParser.java`, but still sometimes parsing errors occur. I have also included a 3rd party parser from [Android-Image-Shape](https://github.com/sathishmscict/Android-Image-Shape/blob/master/library/src/main/java/com/github/siyamed/shapeimageview/path/parser/PathParser.java). To use this parser instead of the default one, set `use_legacy_parser="false"`. This may help in certain situations but not always. If you find any vector that is not being drawn properly, please file an issue and include the vector.
 2. Path morphing is not supported as of now. I would like to support path morphing between incompatible vectors as well (using techniques mentioned [here](https://github.com/alexjlockwood/ShapeShifter#how-does-it-work) by [Alex Lockwood](https://github.com/alexjlockwood)).
