Re: Cannot make '-replace_ex' option work

Hi,
I understood it the way that the tolerance gives a range in which the RGB is replaced.
I set the 5 to have a tolerance of RGB 187 187 187 up to RGB 197 197 197 to be converted to RGB 192 192 192.
That is what I need. But I'm unsure if my commandline is correct.
Regards,

Cannot make '-replace_ex' option work

Hi,
I try to replace pixel several with '-replace_ex'.
I tried this:

Code: Select all

nconvert.exe -ctype rgb -replace_ex 192 192 192 192 192 192 5 -overwrite "C:\Temp\Example.bmp
But no pixel are replaced.
Is 'replace_ex' not working or what is wrong with my commandline?
Regards,
