By visual inspection of an 1200 pixels image scaled to 0.5 using the above code any diferences are indistinguishable to my eye. 2016-08-31 22:40 GMT+02:00 Jens Axel Søgaard : > Is the result as good as ImageMagick? > > Den 31. aug. 2016 kl. 22.25 skrev Tobias Gerdin : > > Right, that did it, than

Oh sorry, I have not tried that deep. Racket logos and icons are also scaled in this way. So for everyday tasks, I think this implementation is good enough especially the backing-scale is taken care. It's better than APIs in flomap and pict. BTW, It's a long period that no one maintains the flomap

Hi Erich, Use `yield` in place of `sync`. Using `yield` will wait for the thread to complete in the same way as `sync`, but it will dispatch GUI events while waiting. Matthew At Wed, 31 Aug 2016 18:10:17 +0100, Erich Rast wrote: > Hi! > > I have a problem with the interplay between the racket G

[racket-users] Problem with threads and GUI event handling

2016-08-31 Thread Erich Rast
Hi! I have a problem with the interplay between the racket GUI main thread and other threads. My application connects to a socket and creates a GUI. Some of the GUI events are sent over the socket, and everything is highly asynchronous -- there are multiple threads and channels between them for so

For the newcomers like me, a small update here to say that proxy support has almost landed in racket. https://github.com/racket/racket/pull/1411 Being behind a corporate firewall, I'm eager to test that! Cheers, Pierre. -- You received this message because you are subscribed to the Google Grou
