renaming output files

if I want to rename the output files with the # placeholder it only generates one image with the number 0. I use this in a batch file like
c:\programme\xnview\nconvert -npcd 2 -q 70 -size 256x256+0 -opthuff -rmeta -ctype grey -corder inter -out jpeg -o "##.jpg" -ratio -rtype lanczos -resize 800 800 "*.jpg"
and expect image names like
01.jpg
02.jpg...
nConvert outputfiles renaming with numeric continuation '#'

hy Ingo !
(and XnView admins also !)
Try to add the
-n option to specify the begin, the end and the step to rename your images, like this :
for this example your new images will be (re)numered from 7 to 55 by step of 1 unit - also 49 files
code wrote:nconvert -npcd 2 -q 70 -size 256x256+0 -opthuff -rmeta -ctype grey -corder inter -out jpeg -n 7 55 1 -ratio -rtype lanczos -resize 800 800 -o "newpath\new_###.jpg" "oldpath\old##.JPG"
("##" indicates where are the numeric references)
If old images are not numered, you can try to substitute "oldpath\old##.JPG" with "oldpath\
*.JPG"
To keep the same directory, don't specify the path
Question for admins : with wildcar ("*") in old file names (like "oldpath\*.JPG[b/]") nConvert converts twice each file (cf. MSDos echo), is it a 
bug of the program or just a bug of the user ?
Other note for admins : 
real bug ; the usage of some characters (in the destination file name) is not appreciated by nConvert (but XnView doesn't bug) : for example, the char "¯" (decimal code 175) is converted into "»" (decimal code 187).
It's annoying me because I use several characters ("¯" included) to code for the pixel size of my images...
XnView... what a kind of pretty toolbox !

in fact, using wildcar doesn't work for more than... 1 file ! : it converts each source file ("*") into each destination files ("#")... the conversion of a source file rewrite (erase) the files created (destination files) with the precedent source file (same files names) !!
So it will be a good idea to add full renaming features to nConvert, with :
- regexp support to filter source files (including capturing brackets) and to rename files (including captured brackets)
- any input files list support (including numered files and Regular Expressions)
- any output files list support (including new numeric continuation and Regular Expressions)

ok, thanks !
the support of special numeric continuation cars ("#") in nConvert (with first number and step to rename destination file) like the -n option select the source file, and like the XnView renaming function do.
Best regards,
especialy to the new versions of XnView
