I'm trying to add a scalebar to my Mapfish Print pdf output but it's always rendering too small.
I have seen a few solutions that suggest using the "geodetic": true setting in my requests, but this makes no difference to the results.
Here's a section of the pdf output demonstrating the issue:
The blue grid marked 75 - 76 is 1 km in size, yet you can see that the scalebar rendered suggests this would be in excess of 1 km if used as the source of truth.
Any ideas how I may be able to get the scalebar to render correctly?
Here's an example request I'm sending to Mapfish Print:
{
"layout": "A4 landscape",
"outputFormat": "pdf",
"geodetic": true,
"attributes": {
"map": {
"projection": "EPSG:3857",
"dpi": 300,
"rotation": 0,
"areaOfInterest": {
"display": "NONE",
"area": {
"type": "MultiPoint",
"coordinates": [
[
19092823.11,
-5325062.01
],
[
19087166.77,
-5329055.85
]
]
}
},
"layers": [
{
"baseURL": "http://tiles-a.data-cdn.linz.govt.nz/services;key=SECRET/tiles/v4/layer=50767/EPSG:3857/{z}/{x}/{y}.png",
"type": "OSM"
}
]
}
}
}
And the following is my config.yaml:
templates:
#===========================================================================
