>What are the proper dimensions of a .png for use by a UITabBar item? I've got one project (which works) which has two 57x57xmillions-of-colors png's using a simple black-and-white coloration. I have another project which also has two 57x57xmillions-of-colors png's (converted from windows .bmp files using GraphiConverter 6.5) that also have a simple black-and-white coloration. But when the UITabBar displays these, they just show up as blue squares with the 'glassy' look. What am I doing wrong?
The only thing that matters is the alpha channel. If the image is completely opaque it will show up as a solid blue square. The "glassy" look is added automatically in any case.
A good way to proceed from an existing image is to turn its visible image into an alpha channel. A good image app will allow you to do that. m.
