The PNG Einstellungen / PNG settings dialog box appears when you press the PNG Einstellungen... / settings... button on the Bild speichern unter / Save Image As dialog box. It lets you control attributes of the PNG image file.
Pixelgröße / 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 45-Bit Pixel benutzen / Use 45-bit pixels and Farbwerkzeug verfügbar machen / Enable color tool on the Projekteigenschaften / Project properties dialog box to learn about 45-bit pixels.
Farbkorrektur / 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 Farbwerkzeug / 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 45-Bit Pixel benutzen / Use 45-bit pixels and Farbwerkzeug verfügbar machen / Enable color tool on the Project properties dialog box to learn about 45-bit pixels.
