Could someone recommend me an easy to use tool for greying-out some images (icons) ?. In an Android application I am doing I have a set of full color icons that I want to use in a tab bar, but I want only the icon at the selected tab to be in color, and the other ones should be shown greyed-out. Then I am looking for an easy way to generate the greyed-out icons from the color ones. Thanks for any help !
Any decent image editor will have a desaturate/convert to greyscale command or a Hue/Saturation/Value editor that lets you do this.
I recommend the Android Asset Studio.
You basically just upload your images and it generates the proper icons for you. It provides a lot of configuration options and all possible types of icons you need.
