[Insight-developers] SimpleITK library size

[Bradley Lowekamp]

Dan,

Those are getting very big!

However, when I look at the size of the release libraries for the wrapped languages:  Tcl is 75MB, Java 74MB etc. The size is quite reasonable as all of ITK and it's libraries are statically linked to it. That means that it includes all of ITK's IO libraries too. Also I have been impressed with how slow it is growing when new filters are added. That has been my primary concern and I think that is still OK. Currently with about about 130 image ITK filter, and IO. I would estimate that the next 100 filters would take like 30 MB more and the current rate.

The 1GB size library does sound very large. But I do believe that we know where the size is going. It's all in the symbol names. More importantly we know that it's in internal symbol names. This points to the meta-programed template instantiation as the culprit. This may be be abled to be shrunk a little by using short names in certain places. However, I am not sure how much effort this is worth.
