Morph-M

h1. Morph-M Python - Python Active Windows

h2{color:#8B0000;background:#ddd}. Introduction

*What Active windows does ?*  

Sometimes, you do not need to work on the whole image. Active window is here to help you ! Define 1,2,3 or more active window on your image, then get all these pixel and work with them. 

Example with images are better than words, so try all example.   

h2{color:#8B0000;background:#ddd}. Example 1: Build 1 image with some part of 2 different images

import morphee as mp

def combineImage(ImIn1,ImIn2):

        #we activate the same window on each image (Red windows)

        ImIn1.setActiveWindow(201,14,1,30,30,1)

        ImIn2.setActiveWindow(201,14,1,30,30,1)

        #copy only active window

        mp.ImCopy(ImIn1,ImIn2)

        # remove active window so all image is actived

        ImIn1.resetActiveWindow()

        ImIn2.resetActiveWindow()

        #Now, we activate the same window on each image(Blue windows)

        ImIn1.setActiveWindow(45,73,0,50,40,1)

        ImIn2.setActiveWindow(45,73,0,50,40,1)

        #copy only active window

        mp.ImCopy(ImIn1,ImIn2)

        #remove active window so all image is actived

        ImIn1.resetActiveWindow()

        ImIn2.resetActiveWindow()

    #write result
