#Project Advance 2

Hi everyone this is the “report” of the project.

This time we are using Imagemagick, Magick++; we can half size the image yeah, but we can’t change the color, ooooooooo u.u, so with this problem we are in a hurry, but we can do it and we feel positive with it because we are in the half of the way to complete this task 🙂

I feel like I´m not doing my best with this project, but here I am trying.

Some links that we found, (more Ever) and  this can help:

http://www.imagemagick.org/Magick++/Color.html#ColorGray

http://www.imagemagick.org/script/perl-magick.php

 

The code:

 

using namespace std;
using namespace Magick;

void newline(){
  coutendl;
}

int main(int argc,char **argv)
{
  InitializeMagick(*argv);
  try{
  int x;
  cout"Hi, Im a manipulator of images "endl;
  newline();
  cout"What do you want to do? (press the number in your keyboard) "endl;
  newline();
  cout"1. Rezise the image to one half of its original size"endl;
  cout"2. Switch to black and white"endl;
  newline();
  cin>>x;
 
  if(x==1){
     newline();
     cout"Alright, now introduce the name of the file with its extension; example: new.jpg"endl; 
     newline();
     Image image;
     string img;
     cin>>img;
     image.read(img);
     image.minify();
     image.write("resized.jpg");
 }
  if(x==2){
     newline();
     cout"Alright, now introduce the name of the file with its extension; example: new.jpg"endl; 
     newline();
     Image image;
     string img2;
     cin>>img2;
     image.read(img2);
     image.quantize(colorspace.gray);
     image.write("blackandwhite.jpg");
 }      
 }
  catch( Exception &error_ )
    {
      cout "Caught exception: " error_.what() endl;
      return 1;
    }
  return 0;
}

 

 

#Project Advance 2.

So, right now I technically push even forward my programming skills, I mean…using imagemagick is a little bit hard, but today I compile some code and it runs!!!

Marco and I manage to resize the image to one half of its original size, but now we´re struggling with the grayscale functions and stuff, at least we have something to keep working on and we feel positive about the results in our final project.

We find some useful functions in the following pages:

http://www.imagemagick.org/script/perl-magick.php

http://www.imagemagick.org/Magick++/Color.html#ColorGray

 <Magick++.h> 
<iostream>
using namespace std;
using namespace Magick;

void newline(){
  cout<<endl;
}

int main(int argc,char **argv)
{
  InitializeMagick(*argv);
  try{
  int x;
  cout<<"Hi, Im a manipulator of images "<<endl;
  newline();
  cout<<"What do you want to do? (press the number in your keyboard) "<<endl;
  newline();
  cout<<"1. Rezise the image to one half of its original size"<<endl;
  cout<<"2. Switch to black and white"<<endl;
  newline();
  cin>>x;
 
  if(x==1){
     newline();
     cout<<"Alright, now introduce the name of the file with its extension; example: new.jpg"<<endl; 
     newline();
     Image image;
     string img;
     cin>>img;
     image.read(img);
     image.minify();
     image.write("resized.jpg");
 }
  if(x==2){
     newline();
     cout<<"Alright, now introduce the name of the file with its extension; example: new.jpg"<<endl; 
     newline();
     Image image;
     string img2;
     cin>>img2;
     image.read(img2);
     image.quantize(colorspace.gray);
     image.write("blackandwhite.jpg");
 }      
 }
  catch( Exception &error_ )
    {
      cout << "Caught exception: " << error_.what() << endl;
      return 1;
    }
  return 0;
}

The first option is the only one that works, we are going to keep working with the colors.

See you later!

What should you work on?

Week #12 and more partial exams for you.

For this week's readings:
C++ (TC1017) should either be looking at support for your project, ImageMagick C++ libraries are a good start.
Python (TC1014) should be finishing chapter 11 (Dictionaries).
