Hi All,

I’d like to add the PNG image output from Geoserver on the web interface with a in a fixed scale.

My.question is What is the DPI of the PNG image generated by geoserver?
96 dpi or 72 dpi?

so that I can set the proper scale (width & height) on the web.

​Thank you very much in advance.​

Hi,

You may wish to see this page of the docs:

http://docs.geoserver.org/latest/en/user/services/wms/vendor.html

There’s a section on DPI:

“dpi: sets the rendering DPI (dots-per-inch) for raster outputs. The OGC standard output resolution is 90 DPI. If you need to create high resolution images (e.g for printing) it is advisable to request a larger image size and specify a higher DPI. In general, the image size should be increased by a factor equal to targetDPI/90, with the target dpi set in the format options. For example, to print a 100x100 image at 300 DPI request a 333x333 image with the DPI value set to 300: &width=333&height=333&format_options=dpi:300”

Cheers,

Jonathan
