Hi all,
I just want to make sure that the folowing behaviour is not a bug. If it
is I will commit it.
The problem is that the result of the following pieces of code is
different:
Code1:
graphics.pushState();
graphics.translate(10,10);
graphics.rotate(0);//!!! rotate by 0 degrees.
graphics.drawRectangle(0,0,100,100);
graphics.popState();
Code2:
graphics.pushState();
graphics.translate(10,10);
//!!!here the rotate method is commented so there
is no rotation
// graphics.rotate(0);
graphics.drawRectangle(0,0,100,100);
graphics.popState();
When the following methods are executed the result is different.
In the first - Code1 the rectangle is drawn on location 20,20
On the seconde - Code2 the rectangle is drawn on location 10,10
Should the location be different when a rotate(0) method is called.
I am using GEF_3.1.1
With eclipse3.2 M3
I am working on a Linux machine with GTK 2.8.2
Thanks
Thaks.
