-out option help?

is there a list someplace here in the forum or online that articulates
the parameters for the -out option? i just assumed that the parameters
would pretty much match file extensions (as in -out bmp to output a file
named filename.bmp). i recently found, however, that, in the case of jpg
files, the -out option requires jpeg and not jpg for it to work. i'd like to
be able to look up which extensions differ from their -out option parameters.
the list of command line options at the head of this forum does not give
any details in this regard.
thanks,
BabaG

Built-in in the executable.

NO. Output format is "guessed" by input format, not output extension.

It does, just scroll down.

thanks dos386 but i have a couple of questions.
when you say 'built in in the executable,' what does that mean? how do
i use this to find what parameter to give the -out option for a given format?
also, i've seen the list in the topic you linked to. it's the one i referenced in
my original post. isn't that just a list of supported formats? how does that tell
me the differences between extensions and option parameter syntax? i do
notice that jpg is listed here as jpeg. if this list is, in fact, the list of -out
option parameters, maybe someone could amend the line 'Available formats'
to say something a little clearer like 'Available formats. Use these as syntax
for the -out option.'
thanks again,
BabaG

NC -help outputs the list to screen
NC -help > NC.TXT outputs the list into a file
No need for an internet connection to find out

YES. And the problem is ?

NCONVERT doesn't care about extensions. You can save "BLAH.RAR" with "-out jpeg" - it still will be a JPG/JPEG image

Partially.

the problem is that on all my systems and, undoubtedly, a great many others,
jpg is what is used as the jpeg extension. i, and likely others not deeply familiar
with the inner workings of nconvert, assume the -out format option would take
this as its syntax. i just think that, in instances where the syntax differs from
conventional extensions, it would be helpful to have that difference noted.
where it says 'JPEG/JFIF' could also be amended to say something like
'JPEG (JPG)/JFIF'.

>NCONVERT doesn't care about extensions. You can save "BLAH.RAR" with "-out jpeg" - it still will be a JPG/JPEG image
while nconvert is, as you describe, agnostic in regard to the file extension,
it is not in regard to the -out option, which is where the confusion derives. it
might be helpful if the commonly used variations of extensions were all accepted
by the -out option. in other words, if -out accepted both jpeg and jpg for its
syntax. i can see how that might not be possible, though, in which case, it would
be helpful to have the differences noted, something like:
'Starred entries denote available -out formats. -out option accepts common file
extensions as its syntax except as noted.'
another column could be included for variations of syntax.
OR
if file extensions are not the most common syntax for the -out option:
'Starred entries denote available -out formats. Left column also denotes -out
option syntax.'
thanks for the clarifications,
BabaG
