nconvert Filename extension forced to lowercase ?

[hmayer1980]

Hi,

I use this comandline to create thumbnails in a thumbs subfolder with a name prefix on my windows 8.1 64 Bit machine.

Code: Select all

nconvert -quiet -overwrite -o $\thumbs\phoca_thumb_l_%% -opthuff -dct 2 -subsampling 2 -keepfiledate -rexifthumb -ratio -rtype lanczos -rflag decr -resize longest 800  -wmopacity 100 -wmfile "%Watermarkdir%\GeneratePhocaThumbs\watermark-large.png" -wmflag bottom-right %workdir%\*.JPG

The output is fine - except the extension gets converted to a lowercase.
For example file "IMG_1066.JPG" gets converted to "phoca_thumb_l_IMG_1066.jpg" - but should be "phoca_thumb_l_IMG_1066.JPG"

I do upload the thumbs to my website and this is a linux server so filenames are case sensitive and the software searches for an upper case JPG if the original file was upper case JPG.
How do I fix this?
I have not found any option like in XnConvert to preserve the Case of the filename nor can I explicitly specify the output MASK like "$\thumbs\phoca_thumb_l_%%.JPG" - it results in lower case again!

Thanks for your help
Hannes

PS: I found first XnConvert which has more options and from a softare developer standpoint - why isnt nconvert just the commandline tool for XnConvert - why are those two completly seperate with simmilar - but not equivalent capabilities? (why doesn´t the UI of XnConvert just use NConvert?)

I think the only immediate solution is to use a renaming utility to rename the output files from NConvert so that the filename extensions are uppercase, unless someone else knows of a workaround? @xnview?

There is a command line renaming utility which could probably be used in a Windows batch file after your NConvert script to output the filenames you need directly:

You could also make a specific request, possibly in a new thread, for Pierre to add support for case-sensitivity to NConvert, assuming that is possible in the Windows version. Interestingly, there is in fact a Linux version of NConvert...

NConvert and XnView 'Classic' long predate XnConvert and XnViewMP, which are cross-platform with Unicode support and feature acclaimed 'fresh-start' interfaces...

Would another option, if you wish to use NConvert rather than create the thumbnails in XnConvert if that is possible, be to convert the image filename extensions to lower case [using XnConvert for example] and then upload those images and the thumbnails produced with NConvert, both with lowercase extensions?

Thanks for the information.

I was just curious if I do something wrong.
I could do the upper case with batch commands.

Since there was everywhere Windows/Linux and Mac support - change the case of file names breaks everything in linux thats why I wondered.

I use NConvert over XnConvert because in a batch I can create all my Thumbnails at once - 7 different sizes.
General Speaking I would prefer XnConvert if I could really create a batch - generate multiple output files with multiple transformations at once. With nconvert i just created a batch file and drop my folder (=filelist) on it and get all I need.

Thanks for the Input

May I propose a change of the software to keep the case in a future release...

I am curious if there has something changed since there is a new version available?

do you have tried lastest version?

do you have tried lastest version?

It does not work in the latest Version (6.70)

[xnview]

try with

Code: Select all

-no_auto_ext

[hmayer1980]

That is a valid workaround. Thank you.
I still would recommand an improvement of the Software to Keep the original case of the file name components.

Thank you.
