Most of them do not work, for example: Display fadeImageCoarse: (Form fromDisplay: (40@40 extent: 300@300)) reverse at: 40@40 crashes with a DNU.

Comment #2 on issue 3225 by jbaptiste.arnaud: Fade image examples/methods give DNU http://code.google.com/p/pharo/issues/detail?id=3225 it 's a closure problem in previous version one block execute several time keep some var value. It 's not the case now. we should change : fadeImage: otherImage at: topLeft indexAndMaskDo: indexAndMaskBlock and update: fadeImageCoarse: otherImage at: topLeft fadeImageFine: otherImage at: topLeft fadeImageHor: otherImage at: topLeft fadeImageHorFine: otherImage at: topLeft fadeImageSquares: otherImage at: topLeft fadeImageVert: otherImage at: topLeft
