In the distribution package, you can find the config.json
file. This file configures both the multistep editor (not covered in this topic) and the Preflight Tool widget. In this file, you must define such properties as the URL of the server component, preflight rules, and front-end parameters.
You can load this configuration from an external file (as in the provided sample), define it as a variable in JavaScript code, or even read it from your database.
Front-end parameters allow you to set up the workflow and appearance of this tool. Now, let's see how you can configure the preflight widget. The following example represents the params.config object and shows how you can specify a 720 x 576 pt product with 300 dpi, configure the bleed zone, set a preflight rule to check the color space, and enable a button to upload the users' files.
