Higher icon resolution for printing #288

Open mhabets opened 7 years ago

mhabets commented 7 years ago

Could you provide higher icon resolution better appropriate for printing? or may be in svg format from which user can produce whatever desired icon resolution.

FYI: my rendering process steps below (which result in poor icon resolution):

carto project.mml --ppi 300 > HDM_style.xml
nik4.py -b 14.9761 12.0536 15.0659 12.1256 -z16 --dpi 300 --wld kousseri_hdm_z16_300dpi.wld HDM-CartoCSS/HDM_style.xml kousseri_hdm_z16_300dpi.png

If you see any think wrong in my process, please kindly advise me.

I would think that migrating to SVG version of the icons might help a little. openstreetmap-carto now has gone to a policy of almost exclusively accepting only SVG versions of icons. They would be a very good source for those icons. They are also CC0 licensed. Some of the icons could be migrated, but they are using a 14x14 pixel canvas.

Maki is now only releasing SVG on 15x15 pixel canvas. It seems that this project is using an 18x18 pixel canvas. I'm not sure if that is a deal breaker.

It would be some work to do this. It would just come down to identifying icons that there is no an equivalent SVG version.

All sources are already SVG, see https://github.com/hotosm/HDM-CartoCSS/blob/master/icons/poi/_nori.svg and https://github.com/hotosm/HDM-CartoCSS/blob/master/icons/poi/_maki.svg so it certainly isn't that much work to replace PNG ones by thoses. ;)

Can't remember now why I did not keep them as SVG from the beginning. :s
