Hello,
I have noticed that from the demo page of Geowebcache (geoserver 2.1.3) I can't no longer seed in png8 format but only in png format. Which is the easiest way to do that apart from using curl?
Thanks
Should be as simple as turning it on.
Settings --> Geowebcache
As you see below this format is not turned on as a default.

Got an direct Email back (as far as I can see not to the list).
Thanks Christian,
You mean if I turn on only the png8 format (not the png) then on the demo
page of geowebcache GWC Demos Page and for a specific layer (see picture
attached) the option of png8 will be provided?
What I want is to be able to manually seed a layer in png8 format and if
this is not the way can you tell me an easy way apart from curl.
In addition, can you please clarify what will be the affect if i turn on
only the png8 format.
Cheers,
Stephanos
Sorry, one should try before giving 'good' advice. You are right the effect
on the content of the geowebcache demo page
(http://localhost:8080/geoserver/gwc/demo) is zero. On top of it with every
new start the ticks are gone. I thought it would be the purpose of settings,
that they are kept.
One thing you could do though - and I promise I tried this and it works - is
writing the layer into the geowebcache.xml and pointing to your own server
as below. In that case you see the same layer twice as 'bushfire_rone areas
localhost' from GWC and 'bushfire_prone areas' from your local geoserver.
<wmsLayer>

Hello,
Finally, I think I found a way to handle the Layer seeding in PNG8 but I
need your
opinion
I have check the png8 option in Geowebcache general options and now I have
as an option to cache every new layer in png8.
However, the layergroups that I had created before i checked the png8 option
could not be cached in png8.
Therefore to resolve this issue, I created new layergroups like the old ones
that are okay with the caching in png8.
Then, in order not to lose the tiles that are already generated in gwc for
the old layergroups, I think an option is to rename the old layergroup
within geoserver admin panel eg 'Layergroup' to 'Layergroup_prev'.
This will have as an effect the changing of the name of the folder of the
layer in gwc to 'Layergroup_prev'.
After that, within geoserver admin panel we rename the newly created
layergroup to 'Layergroup'.
Finally, in gwc folder we rename the folder of the old layergroup from
'Layergroup_prev' in 'Layergroup'.
Based on your experience, will this process give me the chance to keep the
already generated tiles for the new layergroups while I coul reseed some
areas in png8?
Thanks in advance,
Stephanos

Hi,
I dont know if I understood correctly what you mean but, for the old LayerGroup, you can
enable the image/png8 format directly inside the ‘Tile cache configuration section’ of the
LayerGroup (not from the ‘Caching Default’ section). In this way the LayerGroup can be
cached also in png8 maintaining the old tiles of the other formats.
You have already tried to do this ?
Best Regards,
Tobia Di Pisa
