Hi Christian,
thanks, fixed in SVN 1590.
Best Regards,

Hi,
I would like to announce a new GNU APL feature: ⎕PNG
PNG stands for "Portable Network Graphics" and is a file format,
standardized
in RFC 2083, for (still) images that is, among several other use
cases, also
directly understood by web browsers.
Unlike some of the other image file formats around, the PNG file
format
has no strings attached, such as patents or copyrights. This was
one of the
reasons for choosing it in GNU APL.
While APL appears to be the perfect choice for manipulating the
large pixel
arrays of images, this is not the case for the files on disc
from which the pixel
arrays are read or eventually stored. ⎕PNG tries to close this
gap.
*⎕PNG* is comprised of three simple sub-function for:
1. reading a *.png* file into an APL array of pixels,
2. displaying such an array in a GTK window on the screen, and
3. writing a (supposedly somehow manipulated) pixel array into a
*.png* file.
The main work in the conversions above is actually provided by
*libpng* (see
www.libpng.org <www.libpng.org>) therefore ⎕PNG is merely
a lightweight wrapper around
*libpng*. ⎕PNG is supposed to support all file variants (colour
and grayscale,
different pixel resolutions from 1 to 16 bits, with or without
alpha channel),
on input and most (= all but pixel arrays using colour palettes)
on output.
*SVN 1589*, see also i*nfo apl* section 2.32 for details.
Enjoy,
Jürgen
