Handwriting Canvas

Description

• This is a cordova application for writing and saving handwritten characters. I used it for learning and collecting Japanese kanji data.

Sample

Getting started

Requirements:

• nodejs
• cordova or PhoneGap: npm install -g cordova

Setting up and running the project

• Create a blank cordova project

cordova create [folder-name] [com.example.cordova] [app-name]

• Replace the www folder content with this repository www

• Add your platform of choice. For example, cordova platform add android

  • You will need to install some addition softwares depend on your targeting platform (android will need Android Studio and an Android SDK version)

• Add cordova-plugin

  • Canvas2ImagePlugin:

    cordova plugin add https://github.com/ichisadashioko/Canvas2ImagePlugin.git

• build or run it in your devices

  • Build for android platform: cordova build android

  • Or run on android device: cordova run android

Note

• On android device, images will be saved at /root/sdcard/Pictures/cordova_app/.

• Pre-build apk is availabled at releases.

• If your purpose is to run Tensorflow model inference via tensorflow.js, it's not possible because tensorflow.js use Web Worker API to pull its assets from the server the web page is running. However, cordova application is just offline html-viewer with offline javascript.
