IT 212 -- Project 6

Project 6: Photo Albums

Goal:

• Write a script that renames and organizes image files into photo albums.

Relevant Examples:

• CreateFolders  CreateBackupFiles  CreateSequenceNumbers

Details:

• Select 8 or more images (not more than 20) to be renamed and organized into three or more photo albums. Place your images all in a folder named originals. Your script named proj6Smith.py (replace smith by your last name) and the index file index.txt should be in the folder that contains the originals folder. Here are four sample images:
  arch-de-triomphe.jpg, catedral-barcelona.jpg, eiffel-tower.jpg, sagrada-familia.jpg.
• Resize your images so that they all take up less than 50 K of disc space.
  To resize an image using MS Notepad:
  
  1. Right click on the image in the Windows Explorer
         and open it with Notepad.
  2. Select Main Menu Resize >> In the Resize box
         Leave Percentage radio button selected >>
         Enter 50 and 50 in the Horizontal and Vertical textboxes
              to reduce the width and height of the image by 50%.
         Click OK.
     
     Right click on the image and select Properties to see the new image size.
     Continue to reduce the image disc size until it is less than 50 K.
  
  
  To resize an image on a Mac:
  Right-click (or Ctrl-click) on the file in Finder and select Services >>
      Resize Image from the contextual dropdown menu. You can also drag
      a selection box over several images and resize them all at once using
      the service.
• Your script should read an index file, create a new folder for each album, then rename and copy the image files into the album folders. See the pseudocode below.  Add print statements in your script to tell the tell the user what your script is doing.
• For example, using this index file index.txt, your script will create two new folders barcelona and paris, then rename and copy the image files like this:
  
  Barcelona:  001-catedral-barcelona.jpg   002-sagrada-familia.jpg
  Paris:  001-arc-de-triomphe.jpg   002-eiffel-tower.jpg

Pseudocode

Import os and shutil modules.

Assign previous_album to the empty string ("").
Open index file, call the file object fin.
Read first line of input file.
While input file not empty,
    Use split to obtain fields.
    Assign zeroth field to folder_name.
    Assign first field to original_photo_name 
    If previous_album != folder_name
        Use os.mkdir to create new folder named folder_name.
        Initialize counter to 1.
        Assign folder_name to previous_album
    End.

    # Next two lines are literal Python statements.
    new_photo_name = "{:s}/{:03d}-{:s}". \
        format(folder_name, counter, original_photo_name)
    Use shutil.copy method to copy "originals/" + original_photo_name
        to new_photo_name.
    Add one to counter.
    Read next line of input file.
End.
