I'm crazy... I'm doing a map that is 48x24 inches and I want to export a 1200dpi version (all my elements are scaled down at LEAST by 25%, so the resolution is there). I know that the maximum size is currently arbitrary, but can the program handle this level of insanity? (And just so you know, I'm running 32 gigs of memory, so I'm not worried about that consumption).

The program can, the issue is can your PC handle it? . 32G should be plenty of memory, but depending on how you are doing your map it may be too processor intensive when it needs to re-raster elements.

What kind of map is it? Is it a world map with multiple different continents? Or one single continent? A battle map?

Thank you!

Hey chief,

This is a continental-level map. This isn't a resource issue, but rather an arbitrary limitation of the program. When I tell it that I want at 48in x 24in export at 1200dpi, the program says "Export size exceeds the max size supported by this version". I'm positive my computer can handle it. all 6 of my cores are sitting at about 30% load during a 600dpi save.

Ah, okay. Missed that .

There is a 23000 x 23000 pixel limit that is due to the final raster library in Windows. We have a work around but has been low on the priority for bringing in/testing it since most people don't need to export above that resolution.

We'll try to get to it before the end of the year.

May you provide some information about this library?

Because the PNG file format shouldn't be the problem, since Wikipedia allows uploads up to 2.500 MP (https://commons.wikimedia.org/wiki/Comm ... _file_size) and 23.000px * 23.000px is 529 MP (https://toolstud.io/photo/megapixel.php ... ight=23000).

Format isn't the limit, just the rasterizer. In OSX and Linux we use a different one that doesn't have that limit so we'll migrate to the same one (note, we still limit it in OSX and Linux for consistency).

Alternative: You could rasterize in (possibly overlapping) chunks and stitch them together?

Yep! That's one of the things we are considering.

We'll revisit this after we get a couple more releases with new features and bug fixes. We have several performance and capability improvements planned for our engine

I *really* hate to be that guy, because I am also a software developer and I *hate* it when someone else is that guy, but is there any kind of timeline on when the rasterizer is going to be upgraded? I'm kind of stuck on a project involving what will be a table-sized map.

I'm curious - why do you need 1200 dpi? While many printers can handle this, why do you need it? Even for professional printing, 300 dpi is the standard. Some comics are created at 600 dpi (but still printed at 300). I mean, I work in print quite a bit and have never needed 1200 dpi.
