Welsh Branch progress update

Irfanview PNGOUT isn't bad and neither is Photoshop, but it won't get you nearly as small as you can go.

Try this for size:
http://pnggauntlet.com/

Whilst it'll take a long time to run, you'll save somewhere in the region of 30% total.
Depending on the file you may get as much as 90% size reduction, down to somewhere about a 5% reduction for something that's been through Irfanview.

(On a test run on the Cwm Typsn veichles folder, I'm just over 50% of the way through after 20 mins on a reasonable speed quad core and have saved 5.5mb so far. I'd guess on a total 8-10mb total saving)

Cheeers

EDIT: Whole folder (about 40 pics) done in 1min 7secs on i5. Average size reduction is about 10%...

I might as well try that... I still have the original files. It does convert png's to 8-bit as well, right? It might run quite well on i5 and on Phenom II x4...

No 8-bit, it just applies multiple PNG compressions in sequence.
You'll get less of a drop on 8 bit files, but should still be around the 5% mark I'd think.

Final result on the Cwm Typsn vehicles folder:
12793.25kb saved, in 38:40 mins

Yeah, obviously, as the 8-bit textures are not as big as 24-bit ones. :-)

I know some parts of welsh railways use the ERTMS in cab signalling. A very lookalike to the signalling on the Eurostar

AFAIK that's only one line and acts as a lifesize laboratory for ETCS (ERTMS).
