Re: [mkgmap-dev] How to make a scale-dependent TYP style?

Hi Niccolo,

you must create an own type for each zoom-level.

highway=motorway [0x1 resolution 24 continue]
highway=motorway [0x10101 resolution 23-20 continue]
highway=motorway [0x10102 resolution 19-18]

level 20 is zoom out very far. Try 0:24,1:23,2:22......

Hi to all,

I'm trying to create a map for an old eTrex 10 Garmin device.

Everything works fine, but I don't understand how to make a

custom TYP file that will render roads differently at different

scales.

This is my mkgmap invokation:

mkgmap \

--reduce-point-density=4 --unicode \

--description="$DESCRIPTION" \

--style-file='./styles/default/' \

--country-name='Italy' --country-abbr='I' \

--region-name='Toscana' \

--family-id=9999 \

--gmapsupp 63240*.osm.pbf \

./typ/my_etrex10.txt

as you can see I have customized the default style and I have

provided a custom TYP file to override only _line Type=0x006 and

Type=0x016 rendering. My style defines four levels:

levels = 0:24, 1:20, 2:19, 3:18

The problem is that my custom TYPs are applied the same at any

level (scale), whereas the default TYP are scale-dependant (e.g.

secondary roads are rendered gradually thicker when zooming in).

This is my TYP file, indeed there are no scale-dependant rules!

Am I missing something in the TYP syntax?

[_line]

Type=0x006

;GRMN_TYPE:

UseOrientation=Y

LineWidth=2

BorderWidth=0

Xpm="0 0 2 0"

"1 c #BD9541"

"2 c #000000"

String1=0x04,Way

ExtendedLabels=N

[end]

[_line]

Type=0x016

;GRMN_TYPE: Roads/TRAIL/Walkway or trail/Non NT, NT

UseOrientation=Y

Xpm="32 1 2 1"

"! c #808080"

" c none"

"!!!! !!!! !!!! !!!! !!!! !!"

;12345678901234567890123456789012

String1=0x04,Path

ExtendedLabels=N

[end]
