GIMP crashing systematically with large files

[rich2005]

Quote: However I expected that the result will be 4 smaller images but I can't find them . They are not where the original picture was and doing the search on the name gave nothing . Where can I find the 4 images ?

You find them wherever you started the terminal.

The obvious is make a project folder, put the big images there, run the ImageMagick (IM) command from there and everything will be in that project folder.

However as a Windows example in a Win7 virtual machine, with very limited resources, 2 GB memory, small drive,

Putting the map.png on the desktop and running the terminal from there, (set the colours so you can see it), eventualy comes up with the four out_xx.png files. You do not have to use png. jpeg, tiff will work. Just do not use .xcf, IM can read but not too good at writing.
