This repository contains the complete source code of WritePad Handwriting Recognition Engine (HWRE). It is a self-contained project, which does not require any 3rd party development tools or libraries. Everything you need is here! You can build WritePad HWRE for the following platforms:

• Apple MAC OS X 10.10+
• Xcode 8+
• Apple iOS 9+
• Microsoft Windows 7+ (Desktop and Windows Store DLLs; ARM, x64, i86)
• Microsoft Windows Mobile 8+
• Linux (practically any distribution with ISO C/C++ compiler)
• Google Android NDK, SDK 4+ (ARM, MIPS, MIPS64, ARM64, i64, i86)

Building WritePad Engine

Building the handwriting recognition engine on different platforms

1. MAC OS

Development Environment: Xcode 8+

Open Xcode; open MACOSX/WritePadSDK-OSX/WritePadSDK-OSX.xcodeproj project; build for a desired target. This project will build a static library for MAC OS X.

2. iOS

Development Environment: Xcode 8+

Open Xcode; open iOS/WritePadReco/WritePadReco.xcodeproj project; build for a desired target. This project will build a static library for device or simulator depending on the chosen target.

3. Android

Development Environment: Android NDK 9+ (optional: Android SDK, Android Studio)

To build run <ndk-path>/ndk-build in the Android/WritePadLib folder. Android native dynamic (.so) libraries will be built for all supported CPUs.

4. Linux

Development Environment: Linux with C/C++ compiler

To build simply run make in the Linux folder.

5. Windows (desktop)

Development Environment: Windows 10, Visual Studio 2015 Community Edition or better (older version(s) of Visual Studio can also be used, you may need to create a new solution workspace compatible with older version).

Start Visual Studio and open libuniversalreco.sln in the /UniversalRecognizer/V300 folder. Select the desired build configuration and platform then choose Build/Build Solution.

6. Windows Store/Windows Mobile

Development Environment: Windows 10, Visual Studio 2015 Community Edition or better (older version(s) of Visual Studio can also be used, you may need to create a new solution workspace compatible with older version).

Start Visual Studio and open WritePadReco.sln in the UniversalRecognizer/V300/WindowsStore/WindowsStoreReco folder. Select the desired build configuration and platform, then choose Build/Build Solution.

SDK Tools

Additonal information about building and using WritePad SDK tools will be posted here soon.
