2014-11-01 22:06 GMT+01:00 Tudor Girba &lt;tudor(a)tudorgirba.com&gt;om>: Is there any notion of "view (all shapes) extent"? I am afraid the extent is only defined by the actual Morph, therefore, we can only draw and export the visible part in the morph. Using Athens for exporting, we need a way to create an AthensSurface with the correct (enlarged) extent. The problem is, the extent is defined by TrachelShape but the TRMorph is the one holding the AthensSurface. Your proposed solution in https://code.google.com/p/moose-technology/issues/detail?id=1089#c4 should work, although it does not go through athenssurface>>writeToPng: but instead it creates a form renders on an athens surface copies the rendering on to the imageform export the image form If your code creates a rendering error like NBFFICallout class>>#signalError, it is because the Athens-Api is picky about Fraction as arguments for surface extents or transformations: TRMorph>>#drawOn: .... cs pathTransform translateBy: self extent / 2; "<<----------" scaleBy: trachelCanvas camera scale asFloat; translateBy: trachelCanvas camera position negated. trachelCanvas shapes do: [ :trachelShape | trachelShape drawOn: cs. ]. ...
