MFP requesting wrong zoom level for TMS. about mapfish-print HOT 6 OPEN

Hi Jonathan,

Could you give me the size of the map defined in the config.yaml?

I am making the following request (this is to our live external system, so
should work for you too):

{"units":"m","srs":"EPSG:27700","layout":"A4 Portrait","dpi":300,"mapTitle":"Printed with Compass","mapComment":"","mapFooter":"","layers":[{"baseURL":"http://maps.warwickshire.gov.uk/gs/gwc/service/tms/","opacity":0.7,"singleTile":false,"type":"TMS","layer":"z_OS_Raster_Basemap","maxExtent":[0,0,700000,1300000],"tileSize":[256,256],"resolutions":[2800,1400,700,350,175,84,42,21,11.2,5.6,2.8,1.4,0.7,0.35,0.14,0.07],"format":"png"}],"pages":[{"center":[430552.3,265431.9],"scale":75000,"rotation":0}]}

However, while the map size is correct, the TMS tiles requested are the
wrong scale. MFP is requests tiles at zoom level 9 (which is 1:20,000). It
is supposed to be requesting tiles at zoom level 7 (1:75,000).

Prior to the fix in issue 68, it was requesting the correct zoom level.

You can use the application at: http://maps.warwickshire.gov.uk/inspire/(change the basemap to "Ordnance Survey - Rasters") to see what the map
style is supposed to be like at each zoom level - they're very different
(1:75,000 is a bright garish affair, 1:20k is a washed out thing).

I think this is the bit you want:

      #The Map
        - !map
          absoluteX: 32
          absoluteY: 819
          width: 535
          height: 700

I have uploaded a potential fix but am not completely sure of it. I would
appreciate it if you could try it out. In your example it seems to be
requesting at level 8, not 7 like you want. However when I make a map with
wms (no resolutions) they line up perfectly.

Hi Jesse,
Sorry but no change. The requests are still being made to level 9 (not sure why you think it's level 8 - it's definitely level 9).

MFP log request:
2013-12-23 12:06:40,012 DEBUG [org.mapfish.print.PDFUtils] - loaded image: http://wppgeog3/gs/gwc/service/tms/1.0.0/z_OS_Raster_Basemap/04/8/7.png

Geoserver action request:
127.0.0.1 - - [23/Dec/2013:12:06:39 +0000] "GET /gs/gwc/service/tms/1.0.0/z_OS_Raster_Basemap/04/8/7.png HTTP/1.1" 200 116234 "-" "Jakarta Commons-HttpClient/3.1"

(I'm not entirely clear how Geoserver is logging the request before MFP, but ah well).

This is still happening in the 2.0.0 release.

A side effect of this is that a single A4 map request (the request above actually) ends up asking for ~158 tiles! It should be a small fraction of that.

Hi Jesse,
Did you ever get a chance to look at this further?
Cheers,
Jonathan
