Hi,
In this simple script I am trying to render an offline image and save it as
bitmap.
This is a test to calculate the correct size of bitmap when you have different
pen widths (odd & even)
and different scale.
I think bitmap size calculation is done correctly but there is problem while
specifying the offset before you
draw anything on bitmap.
The script will generate two bitmaps using wx.GraphicsContext and Cairo. In both
the images you can see the drawing
is not exactly in center.
Question : How do calculate offset based on pen width and scale?
Cheers
Prashant
