Hi All,
There is a problem with rendering map, using raster layer:
1. I have rendered image fox lox,loy,hix,hiy via mapnik, using map with srs:
+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0
+k=1.0 +units=m +nadgri...@null +no_defs +over
2. I'm rendering new image in mapnik for the same lox,loy,hix,hiy and same
size in pixels, adding a layer to style.xml:
<Layer name="prerendered" srs="+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0
+lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgri...@null +no_defs +over"
status="1" clear_label_cache="0">
<StyleName>raster</StyleName>
<Datasource>
<Parameter name="file">/mnt/var/img/test.tif</Parameter>
<Parameter name="format">tiff</Parameter>
<Parameter name="hix">117407.275446</Parameter>
<Parameter name="hiy">6770486.217388</Parameter>
<Parameter name="lox">78271.516964</Parameter>
<Parameter name="loy">6731350.458906</Parameter>
<Parameter name="type">raster</Parameter>
</Datasource>
</Layer>
as a result I'm getting image with prerendered image shifted up for some
pixels (Only UP, North - I'm was playing with UK map)
But, following the logic, these images should apply exactly one to one.
Maybe someone face such problem before?
