hi all,

i am new imagemagick and i have to merge two map

i use following comment "montage merged1.jpeg merged2.jpeg -mode Concatenate -tile x1 mergedlast.jpeg"

and then

application error occurs and it said " the memory could not be written" on ibm x series 226 with 4gb ram

merged1.jpeg= 11.555 kb and 5088*9000
merged2.jpeg= 9.555 kb and 5088*9000

i need help pls

i hope there is a simple solution

We ran a memory debugger on your command and no problems are reported. We're using ImageMagick 6.3.8-7, the latest release. Try adding '-limit memory 1 -limit map 1' to the beginning of your command line to force the pixels to disk rather than memory. See if that makes a difference.

thaks your response,

i may be find out "the memory could not be written " error reason

there were two different imagemagick version at the same time on computer , after one of them is removed , the command ran without error,

but now my maps bigger (50 mb) and the error is 'insufficient memory case 4 '

hi again,

i add '-limit memory 1 -limit map 1' command and no error
thanks a lot.

and now i try to merge 200 mb maps

Issue your command and go eat lunch. It will complete successfully eventually. You can speed up the process by upgrading your distribution of ImageMagick and running on a faster computer with more memory or using some other program. See http://www.imagemagick.org/script/architecture.php for a discussion on why ImageMagick can be slow with large images.

Another simpler method to merge images is the -append and +append commands

See:

http://www.imagemagick.org/Usage/layers/#append

I do not know how it compares in speed and memory requirements to montage with mode concatenate, but the command is much simpler.
