Hi Gastón,

Thanks for your remarks. I need of feedback for the road map. Artefact is like a baby ;-)

Best regards

and you can use "transposed" for more elegantly :) 
 
* In PDFFormat>>setPortrait and >>setLandscape maybe #defaultSize should be used instead of #size to get size, because otherwise, two consecutive #setLandscape result in a portrait size.

setPortrait
"Set the page in portrait orientation"
self portrait: true.
 self size: (self defaultSize x) @ (self defaultSize y). 

setLandscape
"Set the page in landscape orientation"
 self portrait: false. 
self size: self defaultSize transposed

Regards.
