| 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.

You did not mention the actual IM command used!
More than likely your actual image is 36x36 but it is on a larger
canvas.
Check what identify reports for that image!
It will probably look something like....
crop.gif GIF 40x30 70x46+10+10 PseudoClass 256c 2.1kb
This image is 40x30, but is on a later 70x46 canvas!
Resize reszies a canvas, NOT the image.
To fix try...
convert in.gif +repage -scale 18x18 out.gif
