Overview

Xamarin Forms is great for developing cross platform applications (certainly very sane) but it is missing some important features:

• Patch scalable images
• SVG images
• Single point of use, cross platform, multi-screen / multi-resolution image management
• Simple, markup formatted text for labels and buttons
• Single point of use, cross platform, custom font management
• Segmented button control
• Pop-ups as a first class layout element
• Multi-object Clipboard and Inter-app Data Sharing
• PNG and PDF generation
• Printing

Android developers can use NinePatch bitmaps, the drawable directory naming convention, Html.FromHtml, and a bunch of complex file manipulations to address the image issue. Likewise, iOS developers can use ResizeableImageWithCapInsets, the @2x, @3x, @4x file naming convention, and some 3rd party libraries for this purpose. Custom fonts are a bit more complicated and label layouts take things up another notch. Forms9Patch enhances Xamarin Forms to make multi-resolution / multi-screen image management, custom fonts, and HTML text formatting easy for NetStandard, PCL and Shared Library applications for iOS, Android and UWP.
