Can I Print It?

Can I Print It? by ArtSquare

This repository contains the source for the Can I Print It? Web application sponsored by ArtSquare. The application opens a local image file using the JavaScript File API, determines the image’s size in pixels, and calculates what standard print sizes are suitable based on aspect ratio and DPI.

Project layout

Can I Print It? is a Spring Boot application serving a mostly-static single-page modeless site. Maven is used as the top-level build system, and the spring-boot:repackage goal is run in the launcher module to produce a runnable jar.

The bulk of the code is contained in the resources module, which is a Mimosa project. Maven simply installs and invokes Mimosa to process the Web resources and then copies the output into a Web jar for the launcher.

Building and running

This project requires Java 7 or higher, Maven 3.1 or higher, and NodeJS v0.10.35 or higher (including NPM 2). No other dependencies need to be installed.

Run the command mvn package from the project root directory. Maven will install the Node and Bower packages needed for Mimosa to run. The result of the build will be a self-contained executable jar in link:caniprintit-launcher/target/ that can be run with java -jar.

After Mimosa is set up, resources can be processed in development mode by running ./node_modules/mimosa/bin/mimosa watch from the caniprintit-resources module directory. Runtime resource refresh requires that Maven serve the Java classpath out of the on-disk layout instead of the packaged jar for caniprintit-resources; the ArtSquare team uses m2eclipse workspace resolution to handle this.
