I've recently created an XCF template file that almost only contains
large slabs of solid colors (i.e., no "picture"), couple of layers and
layer masks. I was surprised to find that the XCF compressed this rather
poorly, even though this should be an ideal case for lossless
compression.  

Sigh!

*Of course* I forgot to include the link to the image. Here it is:

Well, I opened that and then saved it as a .xcf.bz2 file and it was 10% of
the original.


[shlomif@telaviv1 ~]$ ls -l template.xcf*
-rw-r--r-- 1 shlomif shlomif 946164 Jun 14 11:06 template.xcf
-rw-r--r-- 1 shlomif shlomif  92386 Jun 14 11:06 template.xcf.bz2
-rw-r--r-- 1 shlomif shlomif 105813 Jun 14 11:06 template.xcf.gz
-rw-r--r-- 1 shlomif shlomif  52708 Jun 14 11:06 template.xcf.xz



Pretty reasonable to me?
