Re^5: How to keep Imager's image files small ?

I stand corrected. Thankyou.

Out of interest, what triggers the writing of a 4-bit per pel .png?

Is it simply if the image is palettised and only uses 16 colors? I couldn't see any mechanism for forcing it.

In the absence of evidence, opinion is indistinguishable from prejudice.

Exactly that. Unlike GIF, PNG supports direct colour, so there's no need for the automatic to_paletted() that writing a GIF does. I've considered adding an optimization option, but it's low priority.	[reply]
