This PDF opens on the Mac but not in any iOS device

On the Mac I get it to load correctly (for the most part):

On the iPhone and iPad I get this error:

What's going on? How do I resolve this?

All other PDFs seem to work fine on both platforms.

I confirm, weird but even when downloaded is not possible to open or actually render it.

Speculation here: depending on how the PDF was generated, can cause problems. For example, I recall a couple of years back where a person was having problems viewing a brochure that was in PDF format: the PDF was saved using the settings for commercial printing and that setting was causing rendering issues when viewing.

In this case, Adobe Reader pulls it up, Dropbox as well.

The graphic you refer to caught my interest so I went to the website (https://landartgenerator.org/index.html) to learn more about how this was created.

The website has a page with a variety of other .pdf graphics, which do open correctly on the iPhone, see this page:

Land Art Generator

landartgenerator.org

However the specific graphic you have selected is not included on that page for some reason. It is described on this page, which is where you obtained the link to the .pdf itself:

Land & Ocean Areas to Support a 100% Renewable, Zero-emissions, Regenerative Global Economy

What does a 100% renewable energy world look like? The latest information graphic from the Land Art Generator Initiative takes a deep dive into the land use impacts of a world powered only by renewable energy.

I am guessing that the difference here may be at least in part due to the resolution and ultimate size of the image. The link above states that "in the full-resolution PDF version you can zoom in on every city". I'm not sure I can actually get that to work on my computer, when I try to zoom to that level of detail it doesn't seem to actually get to that fine resolution. But the file itself is probably different than the other .pdf files on the website, in how it is built up to contain all of the embedded data, and that is probably why it is not working on an iPhone. It is not a 'normal' .pdf, I think.

By the way, that is a terrific website. I appreciate your bringing attention to it.

Same. Just a bit of blue flicker over and over until it just fails.

I thought about that but didn’t know enough about different PDF save settings to ask coherently. I think I’ll try to contact them and let them know.

Thanks! I’ve loved the stuff they’ve had for a long time now.

You’re correct about the source and description of the document. On my Mac I’m able to zoom in on it pretty well. I think it takes a little time to resolve a zoom level but it does get there.

Doesn’t open in iOS 14 either. Reports a crash.
