HowTo reduce size of RootEventDisplay ps pictures

The default version of the ROOT(in 4.10.0) is v3_05_00a. It contains a bug (a feature) in a generation of ps files.

ROOT v3_05_00b has this bug fixed.

The patched ROOT version gives us the decrease in the size of the output ps file by a factors from 2 to 25.

It is much easier to insert the decreased ps file to paper, note, meeting transparency, it will take less time to print out the picture.

You may wish to compare ps files I have recevied using default version of ROOT and a patched one:

2 times decrease:

COT view(default)[601k]
vs.
COT view(patched)[295k]

25 times decrease:

COT view: hits within IMU chamber(default)[548k]
vs.
COT view: hits within IMU chamber(patched)[23k]

All you need to get a fix is to setup patched version of ROOT:
setup root v3_05_00b -q KCC_4_0

There is a good script which may save you 20% more: ps2ps.
It should be executed as
ps2ps input.ps output.ps
