Chapter 7. Publishing > The PNG Tab

The PNG Tab

PNG images have similar options to the GIF image, so we will go over only the differences. First is the Bit Depth (see Figure 7.10). Because PNG images are built on a bit-depth system, they can have transparency in the image itself. This is very useful when doing “cutout” images and shapes. The only way to get transparency in the PNG is to set its Bit Depth to 24-bit with Alpha (the default choice). If you do not need your image to have transparency in it, choose either 24-bit or 8-bit for a smaller file size.
