Button Generator

This node module generates a buffer of a button png image based on a set of parameters. It is used in the Usabilla Themes Publisher to create feedback buttons.

Setup

yarn install

Usage

For generating a button we require these properties:

• A font CSS url - options.fontCssUrl OR a font file url - options.fontFileUrl (optional, will default to CSS url if both are defined)
• A string for the font name - options.fontName
• A number value for the font size - options.fontSize
• A hexadecimal code for the background color of the button - options.backgroundColor
• A hexadecimal code for the text color of the button - options.textColor
• A number value for the border radius (px) - option.borderRadius
• A number value for the width of the button (px) - options.width
• A number value for the height of the button (px) - options.height
• A string for the content text of the button - options.text
• A string for the placement position of the button. The available options are: right, left, top, bottom. - options.edge

The method generate(options) will generate a png buffer.

Example

const options = {
  fontCssUrl: '//fonts.googleapis.com/css?family=Open+Sans',
