Parameters

image  Image

The Image to save. If contains multiple images or frames, then only the current image or frame will be saved.

fileName  String

The name of the file to which to save the image. The directory of the specified path is created if it does not exist.

allowFullScan  Boolean  (Optional)

to allow scanning the whole image for each layers to be able to re-use the local palette of the current layer.
to expand the initial layer area to the local pixels only. This parameter is optional.
Default value: .

backColor  Color  (Optional)

Colors with alpha (transparency), whose Color.A property is equal to or greater than alphaThreshold will be blended with this color during the encoding. The alpha value (Color.A property) of the specified background color is ignored. This parameter is optional.
Default value: Empty, which has the same RGB values as Black.

alphaThreshold  Byte  (Optional)

Specifies a threshold value for the Color.A property, under which a pixel is considered transparent. If 0, then the final composite image will not have transparent pixels. This parameter is optional.
