Create 36" Round Deign in Sections - CWO4Mann - 02-26-2020

I have a design which must be printed to fit in a 36" circle.  I must print on separate pieces of 8x10" paper to transfer the image for the final design.  How can I do this?  I tried making pie-shaped sections but that does not come out correctly .  I appreciate any help.
Thank You
Dave

Cut you image into several sub-images, that each fit on a 8"x10" sheet. Remember that you print likely has margins (there is almost at least one at the bottom of the sheet).

OTOH the image you show looks very pixellated... and 36"" at a decent print definition (150PPI) is quite big (5400x5400px). This would be better done with vector graphics (i.e., InkScape).

FWIW: A quick redraw in Inkscape as a vector. Not exact but close, maybe someone can improve it. (attached)

Just a note, normally avoid real world units (inches) like the plague, Gimp works in pixels, however in this case...

For that size I would say 150 ppi is ok. A slightly larger canvas for working room 40'' x 40 '' @ 150 ppi is 6000 x 6000 pix 

Import a svg vector like this: https://i.imgur.com/K0a0rh7.jpg

Then for dividing it up I would make a selection say 10'' x 8'' and move it around. There is a mode in the move tool for selections. Guides can be added using Image -> Guides -> New Guides from selection  https://i.imgur.com/Jyc0Qpa.jpg

 and eventually that large image split up into printable sizes using Image -> Slice using Guides.

All a bit sketchy but it is time to pack in for the day. Wink

Just a couple of thoughts.
It is symmetrical so you only need half. That will reduce memory requirements for the computer
there is an program to divide up for printing see: https://posterazor.sourceforge.io/

Yes, but not a bilateral symmetry due to colors, so unless you have a good technique to splice things rotated by 72° you can't take advantage of it.

Yes, you are of course correct. Lots of fiddling required. Not practical.
