Running last one again - https://mapknitter.org/maps/lincoln-peak-vineyard/ - at 10cm/px, in same open window... IT WORKED! ~7000x5000 px output, @ ~5mb:

Now trying at 5cm/px 😅 This breaks my browser, but... it worked @ 15mb: https://mapknitter-exports-warps.storage.googleapis.com/1585685256/1585685256.jpg (14000x10000px) it also generates a 543mb tif at: https://mapknitter-exports-warps.storage.googleapis.com/1585685256/1585685256.tif |
OK, so, noting that while exporting works, there seem to be some inconsistencies on local saving of export status:

Wow, @icarito doesn't see the discrepancy but noting here i saw a discrepancy on both browser downloads and |
OK so we can bypass by:
let's do this |

I suppose this ought to do it: |

Confirmed it worked... not 100% sure it busted the cache but it ought've -- we'll publish to production to confirm in a sec... |
Confirmed! |
OK, haha i think i reached the limit: https://mapknitter.org/maps/2011-08-06-brooklyn-newtowncreek-north 13960x20698 px 1.15589GB 2020-05-07 22:18:28 +0000 stalled at making a JPG from that 1.15GB GeoTiff 😂 |

Oh wait that is for the app itself not the exporter... |
It probably ran out of memory? I mean, imagemagick will crash with a gigantic enough image. I think not super high priority as it's probably beyond the limit of what we'd want to support. 13k x 20k pixels is a TON. |
We've just published the new MapKnitter cloud exporter for the first time, in a beta mode. We're very excited to try it out before putting some final touches on it!
The design and user interface is not complete (no worries, it'll improve!), but we'd like to ask people to try running exports on some big maps to test out the exporter on some tough maps.
Edit the map
To run the export, click Edit this Map:
Select images
Then shift-drag or shift-click images you'd like to export:
Start the export
Look in the upper left of the window and click the down-arrow export button:
Choose a resolution
Wait for the completion dialog box
Copy that message and paste it into a comment below, along with anything that went wrong! Thanks a lot!
Example export
Please include:
