• FiltersDllPy:
  wrap all the filters functions that currently dll has, but hasn't a simple
  interfaces for advanced use. This mean that for functions like getOutputArrayPointers
  or other you have to talk with specific C "functions", like pointers, addressof, etc...
  In the future, I'll create another, more "pythonic", class that will solve this, but for now
  enjoy with this code!
  For more info about this, see the C filters example and its python conversion, so you
  can see with your eyes the problems.
• Usage:
  For use FiltersDllPy you need only python, ctypes and filtersDll.
• Download:
  FiltersDllPy here: link
  FiltersDll here (download always the last "Developer release"): link
• Basic simple installation:
  Unpack this package into a directory. Copy the library (.dll) and image (bpm,jpg, etcc) that you find on filterDll
  package (filtersDll_VERSION/bin/) on the FiltersDllPy directory and execute the python test file!

FreeDllPy usage are simple:

#Start to import and instance the class
import FiltersDllPy as FDP
f = FDP.FiltersDllPy()

inImg = "blob2.tif"
outImg = "testFiltersDllPy_output_sobel.jpg"
filterName = "filterSobel"

#Load the image
imageLoaded = f.loadImage(inImg)
imageSobel = f.CreateImageLike(imageLoaded)

#Create a parameter list with the filters syntax
#You can specify the paramters type
par = (("inImage",imageLoaded,FDP.P_IMAGE),
("outImage", imageSobel, FDP.P_IMAGE),
("blurIteration", 1, FDP.P_INT),
("gain", 5, FDP.P_INT),
("thresholdLower", 1, FDP.P_INT),
("thresholdUpper", 255, FDP.P_INT),
)

#or leave the library to found it!
par = (("inImage", imageLoaded),
("outImage", imageSobel),
("blurIteration", 1),
("gain", 5),
("thresholdLower", 1),
("thresholdUpper", 255),
)

#Create a filter and run the paremters over
f.createFilterRun(filterName, par)

#Save the image
f.saveImage(imageSobel, outImg)
