Further to that last message, I'd been trying it in the OnPaint() handler
because when I tried it in the Main() function where the bitmap is loaded, it
didn't do anything (though wxLua didn't protest at my usage). I tried again,
with mixed results.
local DC,C,P=wx.wxMemoryDC()
DC:SelectObject(BITMAP)
local X,Y,x,y=string.find(T[1],"^(.-)\t(.-)$")
for N in ipairs(T) do
C=wx.wxColour(255,0,0) P=wx.wxPen(C,1,wx.wxSOLID) C:delete()
DC:SetPen(P) P:delete()
_,_,X,Y=string.find(T[N],"^(.-)\t(.-)$") DC:DrawLine(x+0,y+0,X+0,Y+0)
x,y=X,Y
end
DC:SetUserScale(0.5,0.5)
DC:SelectObject(wx.wxNullBitmap)
DC:delete()
At the location right before delete, it does nothing. If I place it before the
track drawing to wxMemoryDC it scales the track nicely. But at no point will it
scale the bitmap. I was thinking that bitmap was loaded to the MemoryDC and was
being drawn on directly by that track, but it can't be if one scales but not
the other. Now I don't know exactly what I have...
