Any transparencies and alpha channels from the image files will be preserved.

The selection may also be saved in what is known as an alpha channel.

It's amazing how many self-identifying nerds don't know what an alpha channel is.

An additional alpha channel may specify a transparency mask value.

Images can have 64-bit pixels with 48-bit color and a 16-bit alpha channel.

Such packages can generate images or video sequences with an alpha channel, which stores all the transparency information.

When an alpha channel is added, up to 64 bits per pixel (before compression) are possible.

It was also the first version with full support for alpha channels.

All new changes will have to undergo code review and automated testing before being rolled out in the alpha channel.

An additional alpha channel is sometimes used to retain information about pixel transparency.
