Hi, I think we should decide where and how we write codes, in the text with a snippet style and/or at the end with a full code. I don't know how it depends on the journal where you want to submit the paper. Have you reached a consensus about that? Thank you. Best. -- François Boulogne. http://www.sciunto.org GPG fingerprint: 25F6 C971 4875 A6C1 EDD1 75C8 1AA7 216E 32D5 F22F

Sheesh. Licensing is hard. =) Having read CC0, I'd be ok with the examples being under that license. I'll let you decide whether you prefer the dual-license complexity. Juan.

Hi Stefan, Basically I am OK with this, but doesn't that mean that we have to ask every single person who ever contributed to the examples section for permission? What's the effort to include a small BSD license footnote to a slide opposed to asking all these people and having two different licenses in the project?

Hi, folks I just realised that having our examples licensed under BSD technically means that one has to display the license even in slide shows. I'd like to make it as easy as possible for people to advertise our tools, so could we consider relicensing those as CC0? Regards Stéfan

A bit arcane, but here goes: from skimage.io._plugins import freeimage_plugin freeimage_plugin.write(array, filename, flags=freeimage_plugin.IO_FLAGS.JPEG_QUALITYSUPERB) StÃ©fan

imsave PIL quality for JPGs

Hi everyone, Does anyone know how to set the quality of JPG images (the PIL plugin does not expose the "quality" parameter)? Is there another plugin that lets one adjust it? Thanks, Johannes

We've considered this before (recall discussions about multiple backends), but in the end found that it is not viable to maintain multiple implementations of the same code (at least not for our small team). I am putting my bets on tools like Numba, Parakeet, etc. to save us from Python's slowness. StÃ©fan

Sorry, I must have been unclear; I was not suggesting to include the CUDA code in scikit-image, I don't think cuda is mature and flexible enough yet to allow for an easily maintanable + cross-platform integration in scikit-image. However since I know that you work with large data, I could put this pycuda code in another repository so that it could be used by other people than my team. Emma
