The icons generated through the gulp task: favicon.icon file and favicon-16/32.png files always generate with a white background, and no rounding of the corners, or scaling of the image.
with the following settings:
desktopBrowser: { design: 'background', backgroundColor: '#000000', backgroundRadius: 0.45, imageScale: 0.9 },
it gets a white background-color, no rounding, and no scaling.
Icons generated through the website (HTML5 tab) are done correctly.
I'm using the latest gulp-real-favicon: 0.3.2, package.
