PngImageOptionsBitsPerPixel Property

The number of bits per pixel for indexed output

Get or set the index width used for indexed (palette) output. The value determines the maximum number of palette colors (2 to the power of the bits per pixel), and hence the file size. Valid values are 1, 2, 4 and 8.

This property only applies when Indexed is selected as the ColorSpace; it is ignored for Rgb and Gray.

Default: 8
