All the icons in the TV Station set are in 32-bit (with alpha) and multi-formatted to five sizes: 64, 48, 32, 24, 16
-- except two of them: the first "Cartoon Channel" icon has two sizes (64, 48). The second Cartoon
Channel icon has three sizes: 64, 48, 32.
On the right you can see how one of the icons (NY1) looks in its five formats.
