@cvp said:

UIFont = ObjCClass('UIFont').fontWithName_size_('Arial Rounded MT Bold',22)
attributes = {'NSFont': UIFont}
vo= ObjCInstance(v).segmentedControl()
vo.setTitleTextAttributes_forState_(attributes, 0)

That's perfect, thank you.

how can I set the font size of segmented control titles? The font size it chooses is very small regardless of the number of tabs.
I tried including a font definition in the ui.SementedControl like this:
my_sc = ui.SementedControl(font=('Arial Rounded MT Bold',22))

but regardless of the selection of the font size (vs 22) the displayed tab title size does not change.

That's awesome! Thank you

Thank you. That is cool looking. But I don't see where to input my array of paths. When I ran the script, it pulls from my camera roll.

Yes, all photos in one view. Just like you see when you use
asset = photos.pick_asset(assets)

If I have the path to several photos on my iphone, for example:

/var/mobile/Media/DCIM/131APPLE/IMG_1415.HEIC
/var/mobile/Media/DCIM/131APPLE/IMG_1412.HEIC
/var/mobile/Media/DCIM/131APPLE/IMG_1389.HEIC
/var/mobile/Media/DCIM/131APPLE/IMG_1388.HEIC
/var/mobile/Media/DCIM/131APPLE/IMG_1373.JPG

How can I show these as thumbnails in a subview?

You're right about the photo ratio. It is doing the right thing.

I've been reading the image section in this doc:
http://omz-software.com/pythonista/docs/ios/ui.html#image
Which I just realized is the general section. But I found the Image module documentation (actually the list of all modules which I haven't seen before). I see that I have a lot to learn. Thanks for all of your help.

That doesn't seem to change anything.

That worked for displaying the photo. How would I resize the frame the same as the photo?

Is this better?
