How to add image(s) from iPad camera roll to Pythonista image library

cvp

@themusicman In the file browser, bottom left, a "+" icon, then import, then photo library

Edit: and sorry if I did not understand correctly your question

cvp

You can also work on split view, then drag and drop a photo from your camera roll to Pythonista Files browser

So @cvp - I have done this but I am not sure where the image I allegedly imported has been stored within Pythonista. When I try to select that image as I would for any image selection, the image does not appear anywhere.

So, say I want to use 'emj:Black_Circle' as an image, when I click the bottom right to get the Pythonista dialogue box for adding new image / sound / colour / font etc, the image I just imported is nowhere to be found.

Specifically, I want to add an image from my photo library to use as the background image for a Pythonista app.

Am I doing this correctly?

cvp

When you use the bottom right + button, you don’t import the icon but only it’s name that you can use as ui.Image. named(‘xxx’)

@cvp said:

Aha... thanks for the clarification. Is there a way one can add to the library of images/sounds etc available within Pythonista?

I am not planning on using he UI module in this particular script, but have found a way of displaying and possibly using an image for a screen background using the PIL image library.

cvp

The +, Images, Files shows also your imported images

My first answer in this topic shows how you can import photos from your camera roll. Import stores in the current folder with the photo name, like IMG01244.JPG

themusicman

Thanks @cvp - when I checked originally, after adding the files via the method you describe, I wasn't seeing any files in the +, images, files area. However, and very typically... when I checked immediately after reading your last reply they are indeed there.

Thanks again.

@cvp and how to add sounds that I need? For example, short guitar chords?

cvp

@Karina Sorry, do you want to import sound files into Pythonista? And, if yes, where are they?

Karina

@cvp I want to get more musical sounds like those that are already embedded, but don't know from where to take it and where to save. It's for a program in which I have musical instruments on the screen, and when tap, they play. I also want to do multi touch
Did you ever used your sounds in pythonista?

cvp

@Karina you can search mp3 in Google, import them in Pythonista and play them.
Or even play them as url. Try to search mp3 in the Pythonista forum

cvp

@Karina just for the fun

import tempfile
import sound
import requests
import ui

def play(url):
	with tempfile.NamedTemporaryFile(suffix='.caf') as fp:
		r = requests.get(url)
		r.raise_for_status()
		fp.write(r.content)
		sound.play_effect(fp.name)

v = ui.View()
v.background_color = 'white'

b_piano = ui.ButtonItem()
b_piano.title = '🎹'
def b_piano_action(sender):
	play('https://ccrma.stanford.edu/~jos/mp3/pno-cs.mp3')
b_piano.action = b_piano_action

b_violon = ui.ButtonItem()
b_violon.title = '🎻'
def b_violon_action(sender):
	play('https://ccrma.stanford.edu/~jos/mp3/violin.mp3')
b_violon.action = b_violon_action

v.right_button_items = (b_piano,b_violon)
v.present('fullscreen')

@Karina Sorry, I didn't understand your request. What I show is how to play an entire mp3, not a sound like standard ones. Sincerely sorry, forget my post.

cvp

@Karina you can download a mp3 file and store it in your folders, like an image.
And then, play it like a standard Pythonista file.

cvp

@Karina run this little script once to download a mp3 as a Pythonista file

import requests
url = 'https://ccrma.stanford.edu/~jos/mp3/pno-cs.mp3'
with open('mypiano.mp3',mode='wb') as fil:
	r = requests.get(url)
	fil.write(r.content)

then run your script with this little modif

piano_sounds = ['mypiano.mp3']#piano:A3', 'piano:C3', 'piano:C4#', 'piano:D4', 'piano:E4', 'piano:F4', 'piano:G3#']

Karina

@cvp thanks, I'll try

PinhoBD

@cvp Hi, I tried your approach: +, import, files, Browse, and pick an image file, say, abc.jpg. It imported the file into the current directory, say, /Examples/abc.jpg and the image of abc. But when I checked the + at the lower right corner of the script editor, then clicked open files. There is neither image of abc nor abc.jpg file. I would like to import an image file into + / images/files, so that I can easily enter the image using ui.Imag e.named().I did try many times and some how I did succeed once,but I couldn’t repeat. Please help. Thanks a lot.

cvp

@PinhoBD strange. In + / images / files, I see my thousands images, after some time, I agree

PinhoBD

Thank you. I finally saw the file I imported a few hours before. Now I believe I did the right things. If I can repeat it the second time, I should be able to repeat it again and again. I appreciate your help!!
