Line Symbols and SIZEUNITS

[flavio]

When using other units then pixels, such as SIZEUNITS METERS the values set for line symbols should use those units imho. This is not the case. In the example the "3" should then be 3 meters.

SYMBOL
NAME "dashed-line-short"

TYPE ELLIPSE
FILLED TRUE
POINTS 1 1 END
STYLE 3 3 END

END

Flavio: What does the layer look like that is using that symbol?

For clarification SIZEUNITS refer only to scaling of style properties (SIZE and WIDTH) I imagine, not to the properties within a symbol (e.g. GAP or STYLE/PATTERN). Is the thickness being scaled properly or are we talking GAP etc...

Steve,
as follows:
STYLE 3 3 END
would means that if SIZEUNITS meters, the 3 3 would be meters
this as well for GAP.
SIZE would then be the thickness of the line(?)

in other words my target is to be able to define dashed lines with precise units (as well as symbols with precise gaps ...)

The problem is that certain symbol parameters should really be out in style objects. STYLE (now called PATTERN), GAP, JOIN, CAP will all be moving (or at least available) in styleObj's in the 5.2 release. Then we well be able to consider size in non-pixel units more appropriately.

It's not a trivial change so it wouldn't be appropriate for 5.0.x...

I'm not going to touch this until we move those types of parameters out into the styleObj's. That will happen by 5.4...

wont' happen until 6.0

SYMBOL->STYLE/PATTERN was moved out of SYMBOL and into CLASS->STYLE. Along with GAP, STYLE->PATTERN is now also scaled by the supplied scalefactor.
