Re: [Pharo-users] Pharo image processing library

You may have a look to Cuis library : https://github.com/Cuis-Smalltalk/Numerics There is an image analysis package. We have some plan in PolyMath to port it: https://github.com/PolyMathOrg/PolyMath/issues/158 Best, On Fri, Jan 24, 2020 at 11:20 PM Pablo Navarro <pablo1n7(a)gmail.com> wrote: > Hi everyone! > > Iâm searching for one library for image processing in Pharo.

Great work ! We have a math library with a lot code that might help you here: https://github.com/PolyMathOrg/PolyMath On Fri, Jan 24, 2020 at 11:20 PM Pablo Navarro <pablo1n7(a)gmail.com> wrote: > Hi everyone! > > Iâm searching for one library for image processing in Pharo.

Pharo image processing library

by Pablo Navarro

Hi everyone! Iâm searching for one library for image processing in Pharo. I couldn't find anything (only wrappers) so I tried programming one for basic operations (sum, subtraction) with images using class âFormâ. What do you think about this? For providing a context, I'm studying a PhD. in image processing, but all of the operations that I do, do it in Python. I try using Pharo for more fun :D. Best Regards Pablo.

Re: [Pharo-users] Migration from Spec to Spec2

Hi Kasper, > Le 24 janv. 2020 Ã 20:14, Kasper Ãsterbye <kasper.osterbye(a)gmail.com> a Ã©crit : > Do not silently delete features. Be brave and include a method oddRowColor with a comment saying it is not going to be implemented in this version, and why I add the same issue and I wrote a small fix for TablePresenter. See https://github.com/pharo-project/pharo-launcher/commit/28fb65151a6341f26b91… I have only a few changes but I add to copy FTTableContainerMorph and FTSelectableMorph to add an instance variable on each. Except that, I had 4 methods to implement a basic row color alternance. You can use it as follow in an SpPresenter: self newTable items: #(1 2 3); whenBuiltDo: [ :table | table widget alternateRowsColor ] I will try to do a PR next week for this. Regards, Christophe.

Migration from Spec to Spec2

by Kasper Ãsterbye

Cheers all, There was a mail about Spec2 documentation on this list in the last few days. I had a Spec program, and wanted to see how to migrate it to Spec2. The before and after is the master and the Spec2Migration branches of: https://github.com/kasperosterbye/ovina I decided to write down an account of all my struggles in making this migration. That account is on: https://github.com/kasperosterbye/ovina/blob/Spec2Migration/SpectoSpec2.md Beware - it is LONG. In the end, I draw the following conclusions: - Class comments on which classes to use instead of the depricated ones should be mandatory! - Spotter is a real help - Changing terminology is a true pest - in particular since the terminology of a library is used in the applications - in my case Tab became Page. - The new library has not yet implemented all parts of the old one (but I am sure it has implemented new stuff as well). - The SpDemo class is not only good, it is a template for others to follow. - Do not silently delete features. Be brave and include a method oddRowColor with a comment saying it is not going to be implemented in this version, and why. Some of them refer to specifics of the code. Overall I can say, that earlier today, Estaban wrote: "Widgets API is more or less compatible, chances are that your components will work out of the box or it will be rewritten by a deprecation rule. What is not compatible and there I not auto migration is the layout. You will need to rewrite those.â I am afraid to say, that was not my experience :-) Best, Kasper
