Summary
-------

QT toolkits printer generated pdf are really weird

Type             : Bug
Priority         : High
Gambas version   : Master
Product          : GUI components


Description
-----------

If you set the name in Printer.OutputFile with an extention it have not the same size as if it have not.

QT5 :
With:       482 ko
Without:   59,5 ko

QT4.... ARRRRRGH
With :     9.3 MO
Without :  9.3 MO

GTK2
With :    36.7 ko
Without : 36.7 ko

GTK3
With :     36,7 ko
Without :  36.7 ko



The winner is GTK !!

QT5 is not so bad but only without extention

For the same generation simplescan make a file of : 150 ko but i'm not sur it use perfectly the same pictures.

Well at less QT4 is in a bad moon, and QT5 do strange things.

I join the testdemo source archive.
