PNG settings dialog box

---

The PNG settings dialog box appears when you press the PNG settings... button on the Save Image As dialog box.  It lets you control attributes of the PNG image file.

• See also “Import image file formats” and “Export image file formats” in this chapter for tables comparing the different image formats.

Pixel size
Allows you to choose whether to save the file with 24-bit pixels (8 bits per color channel) or 48-bit pixels (16 bits per color channel).

            This option is available only if the image uses 45-bit pixels.  See Use 45-bit pixels and Enable color tool on the Project properties dialog box to learn about 45-bit pixels.

Color correction
Select this checkbox to save images with uncorrected colors.  Normally images are saved with the colors shown on the screen as affected by the Color tool settings.  Selecting this checkbox allows saving the image file without applying color correction.

            This option is available only if the image uses 45-bit pixels and the Save 48-bit pixels option is selected.  See Use 45-bit pixels and Enable color tool on the Project properties dialog box to learn about 45-bit pixels.
