[Pharo-project] ImageMorph Vs SketchMorph Vs ThumbnailImageMorph

by nullPointer

Hi, excuse me for my english. With old SketchMorph, when was resized with mouse the image did adapt to size of "container", with "stretched" mode. With ImageMorph the size is always the same of Form. I did try then the ThumbnailImageMorph, but when is resized the image disappears and morph is showed like a simple white morph. How can I reproduce the old behavior of SketchMorph? I try for example that-> aImage := ThumbnailImageMorph new openInWorld; grabFromScreen. aImage extent: 50@50. "That lose the visible image and show white morph" I wait I explain your right the problem.

Re: [Pharo-project] fold: ?

by Lukas Renggli

Now I remember: We called it #reduce: because this is much more common among programming languages. The implementation in Pharo is much more general than the one of Squeak. Pharo behaves the same as Squeak for two argument blocks on SequenceableCollection. Squeak does not support anything else.
