GIF compression

Hay
Sorry if this should not go in programming but not sure where else to put it

I have a GIF file of a roadmap which is 16k in filesize

if i make the picture 4x as big (ie double each dimension) the filesize increases exponentially ie. more than x4 , i would have thought it would be non exponential as GIF is very good at compressing large areas of the same colour which is what roadmaps normally have (mine has).

WHAT HAPPEN ?

The kind of scaling where you resize the image. I'm sure you are just trolling though.

Try an image with more data, the SVG header is quite large with a xml declaration, a DOCTYPE and some attributes on the svg element.
