I did a test with wxPython 2.6.1 on Windows. I created a G4 TIFF
image that was 4400 x 3599 big, and the following code took under a
half second.
import wx
import time
def readImage(filename):
img = wx.Image(filename)
w = img.GetWidth()
h = img.GetHeight()
value = img.GetGreen(w - 10, h - 10)
return value
image = "D:\\horizLines1g4.tif"
t0 = time.clock()
value = readImage(image)
print time.clock() - t0, "seconds process time"
print "The value in the lower right hand corner is %i" % value
This prints:
0.488175452467 seconds process time
The value in the lower right hand corner is 255
so it is treating it as RGB, but I bet that's not a problem.
