How to debug crash of image script when it's called as extension

halloleooo

@cvp Thanks for the detailed script.

One thing I am wondering about is: You get the images from the share extension as PIL images via

appex.get_attachments()

and then convert them to UI images. Isn't there a way to get them directly as UI images? I thought UI image is the iOS-native format...

cvp

@halloleooo you're right but we got some problems with images in appex mode, thus...
Else, I use this where you can set type you want

img = appex.get_image(image_type='pil')

JonB

Doesn't appex provide a get_ui_image function? That will be much lighter weight than going through PIL and back.

cvp

@JonB sure, he knows that, but in the past, we got some problems with it.

Édit: believe me, if we go through pil, it is not for the pleasure to do it.

halloleooo

@cvp So what are the problems with get_ui_image?

cvp

Correction: appex does not have a get_ui_image

cvp

We mixed with asset.get_ui_image

cvp

I have been disturbed only because the post comes from @JonB

cvp

@halloleooo doc dixit, you could try with

img = appex.get_image(image_type='ui')

#files = appex.get_attachments()
#for f in files:
files = appex.get_images(image_type='ui')
for ui_image in files:
	#pil = Image.open(f)#,mode='r')
	#ui_image = pil2ui(pil)
	#del pil

I think the Pyhonista docs mentions appex.get_ui_image(). Is this wrong?

cvp

@halloleooo modif just above also crashes with two big photos...

@halloleooo said:

The internal doc, reached via help, and the source of appex.py do not mention it

cvp

@halloleooo but, as I said previously, asset.get_ui_image exists

cvp

@halloleooo print dir(appex) to confirm

cvp

@halloleooo I said"modif just above also crashes with two big photos..." but with pil it works

cvp

@halloleooo ok, now, Forget all, this works, by commenting the del ui_image
and is quicker than converting pil
even with wi=1000 with two photos of 2600x4000 pixels

# assume two images are shared
#files = appex.get_attachments()
#for f in files:
files = appex.get_images(image_type='ui')
for ui_image in files:
	#pil = Image.open(f)#,mode='r')
	#ui_image = pil2ui(pil)
	#del pil
	w,h = ui_image.size
	wi = 400
	hi = wi*h/w
	with ui.ImageContext(wi,hi) as ctx:
		ui_image.draw(0,0,wi,hi)
		#del ui_image
		ui_resize = ctx.get_image()
		ui_images.append(ui_resize)
		del ui_resize

@cvp, sorry, I did not actually try it -- per the release notes there is supposed to be appex.get_ui.image().

didn't actually look -- but
