I made .Scale and .ViewPOrtCenter properties, so tehy can do the right
thing if you set them directly. So you can now do:
class TestFrame(wx.Frame):
def __init__(self, *args, **kwargs):
wx.Frame.__init__(self, *args, **kwargs)
self.canvas =FloatCanvas.FloatCanvas(self, BackgroundColor = "DARK
SLATE BLUE")
MainSizer = wx.BoxSizer(wx.VERTICAL)
MainSizer.Add(self.canvas, 4, wx.EXPAND)
self.SetSizer(MainSizer)
img = wx.Image('mypng(309x34).png')
A = self.canvas.AddScaledBitmap(img, (0,0), Height=img.GetHeight(),
Position = 'tl')
A.Bind(FloatCanvas.EVT_FC_MOTION, self.OnMotion)
self.canvas.Scale = 1.0
self.canvas.ViewPortCenter = (154, -17)
def OnMotion(self, event):
x, y = event.HitCoords[0] - event.BoundingBox[0,0],
event.BoundingBox[1,1] - event.HitCoords[1]
print self.canvas.Scale, x, y
app = wx.App(0)
frame = TestFrame(None, title="Image hitcoords", size=(350,200))
frame.Show(True)
app.MainLoop()
now in SVN, along with this demo.
