Re: [png-mng-implement] png_read_end producing "Read Error"

[J. H. <cot...@ho...>]

Ah... you are right.  The function png_read_png does indeed call 
png_read_end.  This is most likely the problem since the error is generated 
by a line that checks the read count.  The documentation threw me off 
because it says:

"After you are finished reading the image through either the high- or 
low-level interfaces, you can finish reading the file."

So naturally I thought I was missing png_read_end.  Alas I should remember 
the rule: "If it ain't broke, don't fix it."

Thanks for the help!
