png8 images broken

[anthony]

In the recent updates to the PNG coder. It looks like the PNG8 image format was broken.

Code: Select all

  convert -size 100x100 gradient:  -fuzz 30% -transparent gray50 \
          -transparent-color  red  png8:test.png
  convert: Invalid background palette index `test.png' @ png.c/PNGWarningHandler/1429.

Also I am still wanting to know more information about how the PNG coder was changed, and what options users not have to control the PNG image file format generation.
