-[section {PNG OPTIONS}]
-
-The handler provides the following options:
-
-[list_begin definitions]
-
-[lst_item "[option -matte] [arg bool]"]
-
-This option is supported for reading only.
-[nl]
-If set to [const false], a matte (alpha) channel is ignored
-during reading or writing. Default is [const true].
-
-
-[lst_item "[option -alpha] [arg float]"]
-
-This option is supported for reading only.
-[nl]
-An additional alpha filtering for the overall image, which
-allows the background on which the image is displayed to show through.
-This usually also has the effect of desaturating the image.
-The alphaValue must be between 0.0 and 1.0.
-Specifying an alpha value, overrides the setting of the matte flag,
-i.e. reading a file which has no alpha channel (Greyscale, RGB) will
-add an alpha channel to the image independent of the matte flag setting.
-
-[list_end]
-
-The handler provides no true write options at all, but accepts pairs of keys
-and values when writing a PNG file. Each pair will be written as a
-named text chunk where the key provides the name of the chunk and the
-value its contents.
-
-For example
-
-[example {
- png Author <name> Title <title> Description ...

-[section TRANSPARENCY]

-If you want to write images to disk which contain transparency
-information (e.g. PNG with alpha channel) you need at least
