hi all,

i try to split map , i use command 'convert -limit memory 1 -limit map 1 -crop 256x256 -quality 75 MAP.jpeg split_map.jpeg'

i know this command ran before with a map 19000*9000 but this time map is 38000*18000

when i ran this command with map that is 38000*18000
an error occur and is says
" convert: UnableToConcatenateString `No such file or directory'. "


number of the split_maps can be bigger than 10000 , is that a problem ?

Try this command instead:

• convert -limit memory 1 -limit map 1 -strip -crop 256x256 -quality 75 MAP.jpeg split_map.jpeg

The -strip option removes the image profiles which reduces the memory footprint of each image object significantly.

i will try as soon as serves is available

try command now with 50 gb disk space and 4 gb ram

.

the same error again " convert: UnableToConcatenateString `No such file or directory'. "

i think , memory usage is not exceed 1 gb with this command (i look task manager ) and i have 40 gb free space on disk

what am i do wrong ?
