IconView control for Xamarin Forms

Someone was asking on the forum how to draw a colored icon.
I created an IconView control which does this:

The control takes a local image and applies a color on it. This is useful when you want to color images on the fly, without the need to have multiple images for different colors.

At this moment the implementation is for Android and iOS. Contributions for Windows support are welcome!


An example of a Page using the IconView control:
<?xml version="1.0" encoding="UTF-8"?> <ContentPage xmlns="" xmlns:x="" x:Class="IconApp.MyPage" xmlns:controls="clr-namespace:IconApp;assembly=IconApp"> <controls:IconView Source="monkey" Foreground="Red" WidthRequest="100" HeightRequest="100" HorizontalOptions="Center" VerticalOptions="Center" /> </ContentPage>
This draws the "monkey" image with red color in the center of the screen:

Add the control to your project

1. Add /IconApp/IconApp/IconView.cs to your Xamarin Forms PCL project
2. The control uses native renderes. You need to add the renderers to your Android and iOS project respectively:

Note you might need to update some namespaces.
