i wish it was spacing, i really wish
but it can hardly be spacing on this comman

"convert ex1.jpg cluttest2.jpg -clut result.jpg"

it executes perfect from bash
nothing from php

ok this is beyond everything... i reduced it to the simplest thing see this command convert ex1.jpg cluttest2.jpg -clut result.jpg it executes perfect on the bash linux, perfect, perfect result and from php? nothing, zero how is possible, it cannot be a syntax issue, its so simple convert ex1.jpg cl...

same issue with

-auto-level
-alpha opaque
and the others

they do well from the bash
but not from php

do they need different syntax in linux from php?

i thought it was some library missing but its not, i just tried the following clut command from the bash, and it worked and i checked the files and all great the result but it fails from php, some syntax must be, what do you think? convert ex1.jpg cluttest2.jpg -clut +sigmoidal-contrast 3x80% -blur ...

oki another problem in another of the commands, it only works when we remove -auto-level any ideas? so all these commands worked in windows perfect, but in linux they only work if we remove in one of them removing -alpha opaque in another removing -auto-level in another removing -clut why is this, i...

so in two of our commands
it seems that it doesnt like from php using

-alpha opaque

and also

-clut

any ideas?

ok in the first one i showed that doesnt work we have found out that it works if we remove

-alpha opaque

any ideas why?
it works from the bash with -alpha opaque
but from php we need to remove that to make it work, the -alpha opaque

any ideas?

another one that fails and is very simple

$command = "convert ".$source_image." ".$clutimage." -clut ".$target_image ;

this works from the bash
but not from php
any ideas?

having similar problem with this one, i put \ in front of the ( but still not working, i suspect the % signs maybe? what do u think $command = 'convert '.$source_image.' -fill green -colorize 15% -alpha opaque -sigmoidal-contrast 4x15% -blur 1,0.5 \( +clone -fill white -colorize 100 -background &quo...

yes it works
putting the \ before the (
