Re^3: GD Anti Aliasing

All that will have changed is that you've added 4 entries to the palette.

Oh ... why does the MD5 of the output png file then change ?

Cheers,

Because the palette is stored as a lookup table in palettised images. The presence of the 4 extra (but unused) colors causes the md5 to be different. Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. "Science is about questioning the status quo. Questioning authority". In the absence of evidence, opinion is indistinguishable from prejudice. "Too many [] have been sedated by an oppressive environment of political correctness and risk aversion."	[reply]
