Simple Imageview help
-
I want to try to get the following example working. The goal is to have a picture be a sub-view of a scroll view. Why doesn't the following example work?
import ui import Image sv = ui.ScrollView() sv.background_color = 'gray' im = Image.open('Test_Boat') iv = ui.ImageView() iv.image = im sv.add_subview(iv) sv.present()```
-
If you change your Image.open
to
im = ui.Image.named('Test_Boat')
It should work -
ui
uses a different image class thanPIL
. To convert PIL images to UI, I typically use:def pil_to_ui(img): b = BytesIO() img.save(b, "PNG") data = b.getvalue() b.close() return ui.Image.from_data(data)
That function takes a PIL image as input, and returns a ui.Image as output.

Thanks Phuket2. It worked well. I did not see
ui.Image.named()
in the Pythonista documentation so I did not know that existed. -
@donnieh ,
Actually named.image is in the documentation, ui.Image class. In this case I think it's more about examples. I had a hard time with this also before -

@omz doc incoherence still there😢

@cvp did report as https://github.com/omz/Pythonista-Issues/issues/516. Please, try to file issues for these things, it's really hard and time consuming to keep track of all these discussion. Thanks.
