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

[halloleooo]

I have a script which uses Pillow to join images - when I call it from Pyhonista itself (with some default images) it runs fine, when I run it (as it is intended) from the Share menu of, say, the Files app, it crashes.

Problem is I can't find any trace of the crash (no console information or exception backtrace). How can I find out why the script crashed and to what point it got?

We mixed with asset.get_ui_image

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

@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?

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

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

@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
