On Tue, 15 Feb 2005 Dirk Krause uploaded version 1.0.6 of his png2pdf package.
Location on CTAN: /support/png2pdf Summary description: Converter from PNG to PDF, Update and Bugfix License type: gpl
Announcement text: ---------------------------------------------------------------------- The png2pdf program converts PNG images to PDF. An alpha channel in the PNG file can be used to mix against a specified background color and/or to create a PDF image mask or PDF alpha channel.
An option -n or --interpolation was created to add an /Interpolate true entry to the image dictionary. This suggests PDF viewers to show an interpolated image on screen. Previous versions possibly crashed/dumped core when problems occured while reading PNG files. The libpng routines use the setjmp()/longjmp() mechanism on errors but png2pdf did not set up a jump buffer. This is fixed now.

Thanks for the update.
