Re: [Pharo-users] ZnEasy / UTF-8

by Sven Van Caekenberghe

Hi Volkert, Tip 1: use ZnClient and inspect the response in detail, more specifically to see whether the response content type specifies the encoding. ZnClient new get: 'http://<removed>/api/atm/801813'; yourself. Tip 2: you could try to force override the default encoding using ZnDefaultCharacterEncoder (see the class comment). But recent Zn code defaults to UTF8 (see #withDefaultUTF8Decoding: and #withDefaultUTF8Encoding:). So I am curious to see the response headers.

Re: [Pharo-users] Pharo 4 Playground open file menu

by Esteban Lorenzano

I used to think like you (same names think alike ;) ) But Doru and Andrei convinced me that this way is better: 1) you actually have a save of everything you do in your Playground in play-cache subdirectory. You can even change the place your play-cache is, then you can share scripts between your images. You access them with the elipsis button (super cool, I never wrote an external file again after learning this). 2) you can name your playgrounds by double clicking the âPageâ tab. Then they can be found with spotter easily. Some observations here: - would be cool if this named page appears also in the elipsis list (it doesnât) - as I said to Doru, the fact that you can double click and change name is not obvious and I do not thing anyone has realised they can. Adding an edit icon or something that indicates the field is editable would be cool. please, before rejecting it and came back to older ways, give this a tryâ¦ I thought as you (Doru can testify how strong I was on it) and now Iâm convinced this is a lot better and GTools team has a point here :) cheers, Esteban > On 30 Apr 2015, at 21:24, Esteban A.

inverting colors of athens(cairo)canvas

by Peter UhnÃ¡k

Is it possible to invert the colors of a Athens Canvas? After some digging I found paintMode and paintTransform; however the former doesn't support such method (maybe some combination of xor and over?); and the former is only for some specific colors. I also tried changing Color>>asAthensPaintOn: ^ (Color white - self) alpha: (self alpha) "invert the color" and while this works nicely for most cases, it is overriding a library and _doesn't_ work for bitmaps (for obvious reasons). So is there some way how to invert it? Effectively a mask over the canvas. (Doing it at Morphic level should also be a viable option, provided it is possible there). Thanks, Peter
