PNGwriter Changelog

What's new in PNGwriter 0.5.4

• Corrected filegamma_ from 0.5 in one constructor to 0.6 as in all others.
• PNGwriter now handles a much greater range of input files with readfromfile(). In general, the alpha channel is discarded gracefully. Issues remain: A PNG with information in the chroma chunk will not be read too accurately, and a PNG with a transparency chunk will be read incorrectly, though silently.
• Fixed compiler warnings in drawtriangle() and drawbottom().
