The following steps were followed to create multiple png application icons which were used in our mobile apps for both Google (Android) and Apple (IOS) devices:
- Using Flash created a vector icon whose height = width
- Exported the vector as a png image with dimension set to 512×512
- Used Shrink O’Matic AIR application to create smaller png icons
NOTE: Shrink O’Matic provided a better downsize scaling of the image than using flash to export the vector to various png sizes.
Shrink O’Matic is available for download at http://toki-woki.net/p/Shrink-O-Matic/.
From the original 512×512 png icon image:
we generated the following icon sizes for use in Apple Mobile Devices, Android Mobile Devices, Windows Desktop machines and Mac Desktop Machines:
