I just released Raw Thumbailer 47. Why 47? Because it’s GNOME version.

It’s totally rewritten in Rust, still using libopenraw.

The best way to use it is to have it installed as part of the distribution.

Download from GNOME

0.4.0-alpha.2

I just released libopenraw 0.4.0-alpha.2. Actually .0 and .1 got tagged but never released.

Note: the ABI is subject to change.

There is a version on crates.io and the tarballs in the usual place. libopenraw-0.4.0-alpha.2.tar.xz This will build the Rust version of libopenraw to be linked dynamically. The crate works like any other crate. If you were using the libopenraw crate before, short of API changes, it should work.

What’s left to be done:

• A few bit of C API are still missing
• The colour correction needs completing. This is issue 16.

These are just for the goals of 0.4.0.

I hope to have it out in a couple of month.

Changes

Here are the changes since 0.3.7:

New features:

• The library is now written in Rust. This should provide a safer code. Some API changed, see below.
