Export timeline as Image is blank for long timeline

Hello,

I wanted to export a long timeline of a busy day with lots of activity to make an archive record.
Long timeline exports as empty PNG picture.
I managed to successfully export the PNG size of 1179 x 8100. Then I went out again and one more trip, stay, trip and back home was aded to timeline. When I wanted to Export timeline as Image again, I got a blank picture.
Please check if you can export longer timelines. I don’t mind if you split them or make a PDF or multi page PDF. I would save that PDF as a file or send it to Day One Journal.

Yeah this has been a bug for literally years :disappointed: It’s a bug in iOS itself, though that doesn’t help with getting it fixed.

Basically the problem is that Arc is asking iOS “create an image of this view” and iOS comes back with the image data. Except if the view is too big in some way (not necessarily in pixels, but perhaps if there’s lots of image thumbnails in the timeline), iOS comes back with a blank image. It doesn’t say “oops, I couldn’t do that!” or some other error, it just acts like it succeeded, but provides a blank image (albeit with the correct pixel dimensions).

That leaves Arc in a difficult position, because Arc doesn’t know that it’s been handed a dud. From Arc’s perspective it looks like a success.

So what I’ll have to do is proactively have Arc request the images in small chunks somehow, then stitch them together. That adds quite a lot of complexity to a feature that otherwise is very simple. So it’s something that I’ve been putting off doing for a long time. But yeah, it really does need to get fixed.

I’ve bumped the todo up in my lists, and will hopefully get a chance to have another attempt at it soon.
