Affinity Designer Not Responding

[mattius.m]

I've been trying to Rasterise & then Flood Fill a line drawing in Affinity Designer. The dimensions are 5000m x 5000m & the DPI is 300. Thing is that even after I rasterise the drawing (after 3-5 minutes of waiting), if I click 'Copy' let alone attempt to use the Flood Fill tool, the page stops responding. 

I can't even open it & do it in Affinity Photo, I've been trying a bunch of variations over the past 36 hours (this is kinda my job) & now both Affinity programs, Photo/Designer are unbelievably slow regardless of the documents I'm using & are borderline unusable. I've restarted my computer & I have re-downloaded both programs, neither has worked

I have a 2017 iMac with 3.4 Ghz Intel Core i5 processor, 8GB 2400 MHz DDR4 memory, Radeon Pro 570 4 GB graphics thingy if that helps, everything's updated to current MacOS Mojave 10.14.6

Is that a typo or do you really mean your document is 5 km on a side?

Even if @mattius.m actually meant 5000 mm or 5 metres, 300 DPI is overkill for anything other than a highly detailed map.

Hi mattius.m

I've split your post from the other thread, as this is deserved of it's own post. ( @R C-R& @Alfred you may want to re-follow the post as the split hasn't carried this across)

Could you please confirm the above, is the size of your document 5000m x 5000m?

yes thats my bad its a typo, it is only 5000mm

 

I will create a seperate thread & try to tag you both or link it

You don't need to make a new post, as I've already done this for you

Could you please provide a copy of your file to the following link for me?

https://www.dropbox.com/request/yrE9AageCKFlokLn6imE

If you could also open Affinity Designer>Preferences>Performance and provide a screenshot of your settings here, that would certainly be helpful.

okay dokay

I've just sent through the doc.

I rasterised the top layer, then i try to use the flood fill. That's when it usually either loads forever or stops responding

Thanks for that, I can replicate this behaviour here with our document, but I must say I'm not entirely surprised.

5000mm x 5000mm @ 300DPI is equivalent to roughly 60,000px x 60,000px or a 3,487MP image - Designer has to read and interpret each pixel when using the flood fill tool, and this many calculations at once is likely to take some time.

Equally with an image/document this large, the application has to use excessive amounts of system memory in order to keep up. After rasterising the group and using the flood fill tool once the app is using near 12GB of RAM due to the massive size of the image.

May I ask why you're designing at such a size?
