Changes in version 0.1-9 (2026-03-15)                  

    o   update DESCRIPTION, use Authors@R, add ORCID

    o   remove old fall-back binaries on Windows. (#8)
	The local toolchain must include libpng (which is the case
	for all recent versions of Rtools).

    o   the default for text= and metadata= in writePNG() ensures
	that those are preserved from readPNG() if info=TRUE was
	used. (#2)

                 Changes in version 0.1-8 (2022-11-29)                  

    o   minor change to avoid protect and registration warnings

                 Changes in version 0.1-7 (2013-12-03)                  

    o   fix endianness issue in writePNG() on big-endian machines
	when using nativeRaster

                 Changes in version 0.1-6 (2013-08-02)                  

    o   add support for text tags as well as R object metadata
	which is serialized into the text field
	(Thanks to Duncan Temple Lang for the idea)

                 Changes in version 0.1-5 (2013-06-03)                  

    o   add dpi and asp to writePNG() which allows to store the
	image resolution or aspect ratio (via the sPHYs PNG tag).

    o   add info flag to readPNG() which interprets some optional
	tags to return additional information such as dpi, asp
	or gamma if stored.

    o   try to detect local libpng via LOCAL_SOFT on Windows.
	Note that if you use LOCAL_SOFT, you are taking full
	responsibility over the libraries that png will be linked
	against.

                 Changes in version 0.1-4 (2011-12-11)                  

    o   writePNG() now supports binary connection as target and the
	default target is now raw()

                 Changes in version 0.1-3 (2011-09-03)                  

    o   remove debugging output

    o   added a missing call to png_set_interlace_handling to allow
	libpng to de-interlace images

    o   prevent warnings in readPNG() example for the windows device
	which is incapable of any transparency

                 Changes in version 0.1-2 (2011-01-20)                  

    o   support raw array as input to writePNG (RGBA only)

    o   do not truncate 16-bit images in readPNG() if the resulting
	output is not nativeRaster

    o   Windows binary on RForge has been updated to libpng 1.5.0

                 Changes in version 0.1-1 (2010-04-06)                  

    o   add tolerance to writePNG() to avoid shifts by one in
	color because of numerical representation of discretized
	values

    o   adapt to a last-minute change in R 2.11.0 from raster() to
	rasterImage()

    o   add support for more efficient nativeRaster format

                 Changes in version 0.1-0 (2010-03-17)                  

    o   first release on CRAN, supports readPNG() and writePNG()
	for files and raw vectors. readPNG() supports any input
	color type but will convert to 1-4 planes with 8-bit
	accuracy each. writePNG() will write out 1-4 planes
	8-bit each. writePNG() has currenty no provision for
	generating or stroring a palette.
