Hello,
I have an image (gif file) having geometry 36x36.
I scaled this image to 18x18. When I viewed the scaled file in browser the
image appeard to be smaller as expected. But the number of bytes (as shown by
ls -l command) increased for the new scaled down file. How is this possible?
Following are outputs of unix "file" and "ls -l" command on both files.
ls -l in.gif
-rw-rw-r-- 1 prashant users 868 Jun 7 14:15 in.gif
file in.gif
in.gif: GIF image data, version 89a, 36 x 36
ls -l out.gif
-rw-rw-r-- 1 prashant users 1078 Jun 7 14:15 out.gif
file out.gif
out.gif: GIF image data, version 89a, 18 x 18
You can notice that size (on disk) of original file is 868 bytes but that of
new scaled down file is 1078 bytes. This seems confusing to me.
Regards,
Prashant S
