[Patch] Text Rotation in MapCSS

[BrackoNe]

Hi!

I would like most kindly to ask if it is possible to add a support to rotate the text within the map style in JOSM.

I would propose to use text-rotation:"0.05"; which is as same as icon-rotation:"0.05";

I'm creating content-aware traffic signs which are available at the following location:
​https://github.com/BrackoNe/rs_traffic_signs

For the traffic sign which represents ascent or descent (RS:I-3 and RS:I-4), text rotation is necessary:

Thank you in advance,
Nemanja

The rotation centre is might need to be adapted…ç

Did you check that MapCSSRendererTest did not require any change? I would find it surprising.

[BrackoNe]

I'm afraid that I'm not aware of it. I was using a wiki page where you can see all MapCSS objects and I have used it in process of creating this paint style. Can you be more specific, please?

[BrackoNe]

This is one traffic sign:

node|z-15["traffic_sign:background"="yellow"]["side"="left"]["distance_ahead"]::background3_sign_layer_bckground{
  text:"distance_ahead";
  text-color: black;
  text-anchor-vertical: center;
  text-anchor-horizontal: center;
  font-size:"2";
  font-weight:"bold";
  text-offset-x:"-11";
  text-offset-y:"-8";
  icon-offset-x:"-10";
  icon-offset-y:"1";
  icon-width:"15";
  icon-image:"RS/yellow_single.png";
}

If I need to use icon rotation, I would use: icon-rotation: command, as it is stated here: https://josm.openstreetmap.de/wiki/Help/Styles/MapCSSImplementation, in section Icon and symbol styles

I have tried text-rotation, but it is not possible, I'm not sure how to use MapCSSRendererTest and is it possible to combine with this "classic" MapCSS file?

Thanks in advance,
Nemanja

@BrackoNe: comment:2 was addressed to simon04. No action from your side required atm.

[BrackoNe]

Oh, sorry for that.

@team, can someone please review attachment:18468-v2.patch​​

The MapCSSRendererTest test fails on my system also without this patch applied. Here are the generated PNG files: attachment:MapCSSRendererTest-fails.zip​

[BrackoNe]

Any update on this? Thanks in advance.

What's the font used in source:trunk/test/data/renderer/node-text2/reference.png​
When debugging MapCSSRendererTest[node-text2], font in org.openstreetmap.josm.gui.mappaint.styleelement.TextLabel#create is java.awt.Font[family=Droid Sans,name=Droid Sans,style=plain,size=10], but the test fails.

[simon04]

Vincent, would you please help me with the unit test and let me know the required font. Simply, by setting a breakpoint in org.openstreetmap.josm.gui.mappaint.styleelement.TextLabel#create for the font variable. Thanks!

In 16094/josm:

see #18468 - make MapCSSRendererTest run on Windows when JAVA_HOME points to an AdoptOpenJDK installation

[Don-vip]

The font on my system is java.awt.Font[family=Dialog,name=Droid Sans,style=plain,size=10] and it fails too.

I retrieve the reference data on JOSM server from Jenkins, I guess we should add logs so that the exact font can be retrieved in the test output.

Still not much clearer …
