7.20 is out! Check What's New in 7.20 for details. We'll announce to the world in a day or two.

10 August 2009

There's a new stable version, 7.18.2:

http://www.vips.ecs.soton.ac.uk/supported/7.18/

Not much has changed:

new Joe defs (thanks Joe)
fixed a crash building look-up tables with non-zero offsets (thanks Jack)
"header" sets a non-zero exit code if anything failed
tiny stuff

Other vips news:

Replacing gtkplot

We have an experimental branch of nip2 which uses libgoffice to draw charts instead of the venerable gtkplot. Charts look better, need less memory and draw faster. This should help us move to gtk3 as well. We can't merge this change in until libgoffice hits 0.8, sadly.

Replacing gtksheet

We have a branch that uses a treeview instead of gtksheet to display matrices. Sadly it doesn't really work very well. We probably need to try again with an updated gtksheet that's now been picked up by another developer.

Doxygen documentation

Another branch of vips has experimental doxygen docs, you can see a sample here:

http://www.vips.ecs.soton.ac.uk/development/7.19/doxygen/im__abs_8c.html#024953510bd1cdb437e02104c8e111aa

Unfortunately, Doxygen generates program documentation, not API docs, so it tries to document a lot of internal stuff which we really want to keep hidden.

gtk-doc documentation

Yet another branch has gtk-doc support. It's quite a bit more work to get the source into the right shape for gtk-doc, but it seems to make more useful API docs, to me anyway. Samples here:

Google summer of code

Nicolas and his students have been beavering away on new interpolators. They should land in vips in the autumn, hopefully.

Friday 1 May 2009

Our talk on VIPS has been accepted for LGM'09

Nicolas Robidoux has kindly offered to present the talk. Slides here:

7.18 is announced to the world! Thanks to all contributors.

Thursday 16 April 2009

A slight change to 7.18.0 and some windows binaries. I've updated the site to refer to 7.18.x as current stable, we'll announce to the world after a little more testing.

Thursday 2 April 2009

We have a first trial version of vips-7.18. It passes all the tests and works with all my stuff here, so I hope it's OK. We now need testers, so if you have time, could you download and build? I'll make a win32 binary early next week. If things go OK we'll announce the new version to the world in another 10 days or so.

For building, the big differences over 7.16 are:

now uses the "matio" package, if available, to read Matlab save files
no longer needs SWIG to build, since we package the generated files in the tarball
nip2 now insists on flex and bison (it used to tolerate yacc and lex)

So that's one dependency more and one dropped.

We have a What's New in 7.18 page with details, but the big ones are:

new interpolation system (you can finally do bicubic, yay), this is a really important basic improvement we've been waiting years for
new file formats: Radiance and Matlab
nip2 should feel faster and more responsive
