Interface

Clicking Render or Setup in the Render Output File dialog displays the PNG Configuration dialog.

Colors group

  • Optimized palette (256) Choose to render a smaller, 8-bit color file.
  • RGB 24 bit (16.7 Million) Choose to render a true color (24-bit) file.
  • RGB 48 bit (281 Trillion) Choose to render a 48-bit color file.
  • Grayscale 8 bit (256) Choose to render a grayscale image with 256 shades.
  • Grayscale 16 bit (65,536) Choose to render a grayscale image with 65,536 shades.
Note: The 8-bit "Optimized palette" format is dithered, so it does not compress well. The 24- and 48-bit formats do not use dithering, so they compress efficiently.
