-rmeta reduces quality ?

[xenry]

hello and thanks for the wonderful xnview =)

I am trying to write a simple program that uses nconvert to remove jpeg metadata (exif and so on). So I call nconvert with:

Code: Select all

nconvert.exe -rmeta [filename]

all works fine, the metadata is removed, but the jpeg file is a lot smaller ( as filesize ), about 2-3 times. I was wondering whether after the metadata removal the jpeg is resaved with lower quality? Any suggestions will be appreciated. Thanks in advance =)

[xnview]

Yes currently -rmeta doesn't work like clean in xnview, the picture is saved again

[xenry]

thanks for the answer
so is there any way to access xnview->edit->metadata->remove all metadata externally? or any other workaround for removing metadata without losing quality ?

[xnview]

I'll add such option in next version

I'll add such option in next version

Code: Select all

      -jpegtrans op     : JPEG lossless transformations
              rot90  : Rotate 90 degrees
              rot180 : Rotate 180 degrees
              rot270 : Rotate 270 degrees
              exif   : Use orientation EXIF tag
              vflip  : Flip vertical
              hflip  : Flip horizontal
          -jpegcrop x y w h : JPEG lossless crop
          -rmeta  : Remove Metadata (EXIF/IPTC/...) 

The bottom line is not yet lossless in 5.00 ...

And it's still not lossless
