Hi, We are integrating Athens transformation to Roassal2/Trachel and I have reached an issue. In drawing code I use something like this: -=-=-=- athensCanvas pathTransform restoreAfter: [ athensCanvas pathTransform multiplyBy: matrix; âan instance of AthensAffineTransform" athensCanvas setPaint: color; drawShape: self path. -=-=-=- I have a problem, that sometimes it crashes because it expects a float value (I understand why). I suppose I do not have to keep float values in AthensAffineTransform object. My suggestion is to ensure float values where it is expected. For example the method #loadAffineTransform could be like this: -=-=-=- AthensCairoMatrix>>loadAffineTransform: m self initx: m x asFloat y: m y asFloat sx: m sx asFloat sy: m sy asFloat shx: m shx asFloat shy: m shy asFloat -=-=-=- Right now I have to do that transformation myself whenever I use Athens objects. I see it error prone and I do not see it obvious. On other hand I do not want to keep float values in my AthensAffineTransform, because if user do #scaleBy: 0.7 and then #scaleBy: (1/0.7) I want to get the same original value. Otherwise the image could change its size. The same change could be for other methods in AthensCairoMatrix. What do you think? Juraj
