This implements a lossy compression\r\n> method, but all images I tried came out just fine.\r\n> In total, we could save about 36Mb by using this compression on all\r\n> files.

which contains the compressed images at:\r\n> https://github.com/johanvdw/OSGeoLive-doc/tree/compresspng\r\n> I made a single commit per image, so if we merge we can still roll\r\n> back specific images easily.\r\n> In fact, on github, you can watch the images side by side or as a slide over.\r\n\r\nDuring the meeting last night I proposed fixing only those images\r\nwhere the difference was most significant (>50% reduction in size and\r\nfiles of at least 32Kb).\r\nThe results are here:\r\nhttps://github.com/johanvdw/OSGeoLive-doc/tree/compresspng\r\nThe result can be downloaded as a package from:\r\nhttps://launchpad.net/~johanvdw/+archive/ubuntu/osgeolive-docs-compressedpng\r\nAnd it can be previewed at:\r\nhttp://gisky.be/osgeolive-docs/en/index.html\r\n\r\nIn total we save some 34 Mb, most of which is preserved when\r\ncompressing the files.\r\n\r\nSince I did not see any image which is not good I propose to merge this.\r\n\r\nKind
