Hi Gerd Yes, you can do that with a draw level 1 higher than sea. Draw orders are defined at the beginning of a (txt) typ file just before the polygons using the following format Type=0x type number , draworder It is good practice to sort the draworders , as that is how they appear in a typ file [_drawOrder] Type=0x03,1 Type=0x28,1 Type=0x54,1 Type=0x01,2 Type=0x09,2 Type=0x4E,2 Type=0x10F1C,2 etc etc [end] I have no idea what the draworder for sea is , but just make it one higher On 09/12/2019 16:41, Gerd Petermann wrote:
Hi Nick,
I don't want to cut out islands from bay polygons, I thought about a proper typ for 0x3d which somehow marks "calmer water" and a draw order that puts this above water and below any land type polygon. Is that possible?

Hi Gerd
Yes, I suppose so

Hi Nick,
my understanding is that you always have another water polygon, either ocean or natural=water.

Hi Gerd
In case of 2) you need 2 polygons for doing each job; one showing 'water' and the other one not
Ideally, mkgmap checks if islands are in a 'bay' area
In my area we have lots of natural=bays ; fortunately they do not include islands

Hi,
thanks for the help. I see two ways to handle the a polygon with natural=bay: 1) in ponts style with natural=bay & name=* [....] 2) in polygons (as it is now) with natural=bay [0x3d resolution 18]
In case of 1) we just need option add-pois-to-areas In case of 2) we would want to render the water area covered by the bay polygon different, but not anything on the land or on islands. Would that be possible?

Andrzej is correct about how transparency is defined
Garmin regards all polygons with transparency as bitmaps and therefore require 2 colours.
The Bitmap need to be shown below the xpm
If a polygon is completely transparent then a second 'dummy' colour is still needed

Hi Gerd,
I use TypViewer for creating typ files and I don't know XPM details. But looking at TypViewer output, I guess that transparent pixels are defined with color like that:
" c none"
where space ' ' is used for marking pixels.
Changing draw order instead of transparent graphics could be a solution too, but I'm not sure if covered polygon label would remain visible. And without label, there is not much use of this object.
