Getting compare.exe: unable to open image x: error

[manmanda]

Hello,
I just started using ImageMagick software.
In my C drive myimages folder i have two images pic1.bmp and pic2.bmp
When i executed below command

C:\myimages>compare pic1.bmp pic2.bmp x:
compare.exe: unable to open image `x:': No such file or directory @ error/blob.c
/OpenBlob/2647.

Can you please let me know why i am getting this information?

I have never used compare but I am wondering why are you putting x: at the end of your command?
I am sure x: should be an image; see a link to some compare examples

I believe that x: along with show:, etc are for unix only and require X11 to work to display the result without saving the result to disk. You will need to specify an image name and save to disk.

I did wonder if it was something to do with an X server but as I do not have one I could not test it!

After reading all your replies i used below command and it works for me
command C:\myimages>compare pic1.bmp pic2.bmp show: to view it directly

Thanks for your help

I am very surprised that works. I thought show: was for unix only. But perhaps on Windows the delegates.xml file has that line set for some Windows-based viewer.

Also compare generally needs a -metric defined for it, though there may be a default, but I don't know which it is.

Code: Select all

compare -metric rmse pic1.bmp pic2.bmp diff.bmp
