NO.

That you are wrong. The goal of OptiPNG is to create smaller __COMPATIBLE__
PNG's. The only supported compression method in PNG is __DEFLATE__. So LZMA SDK is of no use at all here.
OTOH, the optimized deflate compression algo from 7-ZIP is useful and author
plans to use it one day, has been on the...

Any plans for adding LZMA SDK library compression? Yes, I know LZMA isn't even acknowledged by the W3C consortium. What do you think?.

Hi cosmin,
I too would like to see some type of instructions or pointers on how to go about implementing an in-memory compression. Basically, I am talking about an API which would accept a point to a HBITMAP (?) and output the compressed bytes.
I assume this could be possible by building the source again and tracking the point of entry, but with your help it should be a lot faster ;-)
Regards.

Some small picutres can be smaller by using less zlib window size.

Hi, and thank you for your request.
As I am slowly working towards completing version 0.7, I am happy to let you know that the feature that you requested already exists in the 0.7 alpha branch. This has been requested by many people for a long time, and is listed in the Roadmap section. (See "metadata editing" in the OptiPNG home page.)
There will still be a while before the final 0.7 release...

OptiPNG is amazing, but there is one feature request I have:
I design websites, and gAMA use is inconsistent, well, most noticibly with Internet Explorer, causing problems in it's display. I'd love to see a switch:
-web
That would remove the gAMA, cHRM, iCCP, sRGB, and pHYs chunks from the PNG file, It makes it a one-step solution to fix the problem, as well as further reducing size.

You should be able to use wildcards, e.g. *.png, or /path/to/images/*.png. If you want recursive path search, you could try rOptiPng, an OptiPNG-based tool designed to do just that.

If I didn't miss anything, it is needed to process images one after another, which is slow for many files. I think good idea would by just to set folder where OptiPNG automatically finds every single PNG file and reduct them all.
