[gdal-dev] ogr2ogr PDF

[paul.malm at lfv.se]

Stephen, 

thanks for responding!

I've tried this:
PEN(c:#FF00FF,w:3pt,p:"3pt 3pt")
PEN(c:#FF00FF,w:3pt,p:3pt 3pt)
PEN(p:"3pt 3pt",c:#FF00FF,w:3pt)
PEN(p:3pt 3pt,c:#FF00FF,w:3pt)
PEN(c:#FF00FF, p:"3pt 3pt",w:3pt)
PEN(c:#FF00FF, p:3pt 3pt,w:3pt)
But I'm getting the same solid line. Width and color are ok.

I have also tried to use: PEN(c:#FF00FF,id:ogr-pen-4,w:3pt) 
And I'm only getting the same solid line....

I'm using GDAL 2.4.1, released 2019/03/15
As I understand the PDF driver should handle line patterns.
/Paul

Paul,

Your issue might be one of scale. You have specified units in px try 
changing it to pt. (units (g, px, pt, mm, cm, in))

See: https://gdal.org/user/ogr_feature_style.html#ogr-feature-style

You can also try named pens like:

Here is the current list of OGR pen ids (this could grow over time):

  *

    ogr-pen-0: solid (the default when no id is provided)

  *

    ogr-pen-1: null pen (invisible)

  *

    ogr-pen-2: dash

  *

    ogr-pen-3: short-dash

  *

    ogr-pen-4: long-dash

  *

    ogr-pen-5: dot line

  *

    ogr-pen-6: dash-dot line

  *

    ogr-pen-7: dash-dot-dot line

  *

    ogr-pen-8: alternate-line (sets every other pixel)

System-specific ids are very likely to be meaningful only to that 
specific system that created them. The ids should start with the 
system’s name, followed by a dash (-), followed by whatever information 
is meaningful to that system (a number, a name, a filename, etc.).
e.g. “mapinfo-5”, or “mysoft-lines.sym-123”, or “othersystems-funnyline”

System-specific ids are allowed in order to prevent loss of information 
when dealing with data from systems that store line patterns in external 
files or that have their own pre-defined set of line styles (for 
instance, to do a MapInfo MIF to TAB translation without any loss.)

Examples:
PEN(c:#00FF00,id:”ogr-pen-0”) - simple solid line
PEN(c:#00FF00,id:”mapinfo-5,ogr -pen-7”) - corresponds to MapInfo’s Pen 
#5, and a system that can’t understand MapInfo pens falls back on the 
default “ogr-pen-7” pen (dot-dot line).
