I must be doing something stupid. Where is the Tarif and Availability section.

This is a Macintosh app. The image is composed in Pages, exported as a pdf, imported into Preview, and exported as either a png or a jpg. The images are either 1448 × 1589 or 2880 × 1800.

Thank you

Polyphonic: Thank you for your prompt reply. It caused me to think more deeply about the issue. I have other obligations right now. I'll comment substantively tomorrow after I have thought more on the issue.

I am loading the archived data for a NSOutlineView. My OutlineItems are stored in a tree. Each OutlineItem contains a NSMutableArray (Children). This array contains the children for that OutlineItem. The problem turns out to be with one OutlineItem. Its Children' is shown as an __NSPlaceholderArray when I debug. Apparently it was archived that way due to a bug. Right now, I'm looking for a way to detect items with such an array and delete the item. I'll save the bug itself for later.

A map snapshot is all I would need. Before I spend a lot of work leaning mapkit (which seems pretty dense), I would like to know if a big snapshot would be practical. Would an extreme example like a 10 kilometer square snapshot with 1 meter pixels be feasible (100 million pixels).
