Best method to transfer data to PC

[HT]

Hi,

I've got an app in which the user draws multiple images in succession. The images are stored in an array. I'm wondering what the best method would be to transfer that data to a computer.

Unfortunately I can't get the dropbox synchronator to work. An alternative I tried is to send a mail with the data. But I don't know how to attach the images or how to create a text file with the pixel Matrix that I could attach.

Any pointers?

@HT If your PC is WiFi connected to your iDevice, and if the PC runs a (S)FTP server (standard in Windows or Mac OS), you could send it via (S)FTP, what is quicker than attach an image to an email, send it, receive the mail, detach...

Here’s something you can start from. This one is meant to be placed in the wrench menu, either sending the file being edited or the whole directory to the SFTP server, then executing the code and returning the output, i.e. a fast-feedback development environment for a headless server.

For your purposes, you could save the images to a directory, then send them all to a server.

#coding: utf-8
import paramiko
import editor, console
import os.path
import sys

console.clear()

local_path = editor.get_path()
remote_path = os.path.basename(local_path)
local_dir_path = os.path.dirname(local_path)
remote_dir_path = local_dir_path.split('/')[-1]

server_address = "1.1.1.1"
server_port = 22
username = "username"
password = "password"

print('Open SSH connection')
s = paramiko.SSHClient()
s.set_missing_host_key_policy(paramiko.AutoAddPolicy())
s.connect(server_address, server_port, username=username, password=password, timeout=4)
sftp = s.open_sftp()

fixed_local_root = None
fixed_remote_root = 'magicmirror'
try:
  sftp.mkdir(fixed_remote_root)
except:
  pass # Ok if already exists

if sys.argv[1] == 'dir':
  print('--- Send directory')

  #sftp.put(local_dir_path, remote_dir_path)
  #parent = os.path.split(local_dir_path)[1]
  prefix_len = len(local_dir_path)
  for walker in os.walk(local_dir_path):
    remote_sftp_path = remote_dir_path +  walker[0][prefix_len:]
    if remote_sftp_path.endswith('/'):
      remote_sftp_path = remote_sftp_path[:-1]
    try:
      pass
      #sftp.mkdir(os.path.join(remotepath, walker[0]))
    except:
      pass
    for file in walker[2]:
      print('put', os.path.join(walker[0],file), remote_sftp_path + '/' + file)
      #sftp.put(os.path.join(walker[0],file),os.path.join(remotepath,walker[0],file))
else:
  print('--- Send file')
  sftp.put(local_path, remote_path)

if sys.argv[1] == 'run':

  print('--- Run it')
  stdin, stdout, stderr = s.exec_command('python3 ' + remote_path)
  
  for line in stdout.readlines():
    print(line.rstrip('\n'))
  
  s.close()
  
  print('--- Done')
  
  for line in stderr.readlines():
    print('ERROR:', line.rstrip('\n'))
    
print('--- Complete')

Unfortunately I don't have access to a sftp server. I've got this part of the code, which sends me a mail. I just can't get it to attach the image to the mail:

image = photos.save_image(img)

to = 'receiver'
                        subject = 'data'
                        gmail_pwd = 'password'
                        gmail_user = 'sender'
                        attachment = self.table
                        print('Connecting...')
                        smtpserver = smtplib.SMTP("smtp.gmail.com", 587)
                        console.show_activity()
                        smtpserver.ehlo()
                        smtpserver.starttls()

                    smtpserver.ehlo
                    smtpserver.login(gmail_user, gmail_pwd)
                    # 
                    print('Preparing message...')
                    outer = MIMEMultipart()
                    outer['Subject'] = subject
                    outer['To'] = to
                    outer['From'] = gmail_user
                    outer.preamble = 'You will not see this in a MIME-aware email reader.\n'
                    attachment = get_attachment(image)
                    outer.attach(attachment)
                    composed = outer.as_string()

                    print('Sending...')
                    smtpserver.sendmail(gmail_user, to, composed)
                    smtpserver.close()
                    console.hide_activity()
                    print('Done.')

It prints out "Get_attachment is not defined"

@HT I use this code

# coding: utf-8
import smtplib # for sending an email
# email package needed modules
from email.mime.image import MIMEImage
from email.mime.multipart import MIMEMultipart

import photos
from PIL import Image

def main():			
	# Create the container email message.
	me = 'your email'
	msg = MIMEMultipart()
	msg['Subject'] = 'this is the subject'
	msg['From'] = me
	msg['To'] = me
	msg.preamble = 'Send me a photo'

	sel_photo = photos.pick_asset(assets=photos.get_assets(media_type='photo'),multi=False)		
	photo = sel_photo.get_image_data().getvalue()
	img = MIMEImage(photo)
	msg.attach(img)

	# Send the email via our own SMTP server.
	s = smtplib.SMTP('your smtp server')
	s.sendmail(me, me, msg.as_string())
	s.quit()

# check if the script is running instead of 	be imported
if __name__ == '__main__':
	main()

Hey,
There are many other ways to send data to your pc, the one I particularly prefer is uploading the data to a drive and downloading it on the required device. You may also try FTP server. However, the easiest method would be to use different applications that send songs, images to devices using wifi like ShareIt. You could also use the inbuilt bluetooth in your devices, if it is available. Try transferring https://sc-downloader.net/ songs with above mentioned ways to know which one is best suited for your device.
