OMEdit does not honour line thickness in connecting lines

[massimo ceraolo]

Modelica diagrams can be more effective if some connecting lines are twice the normal thickness. For this purpose one could use the is parameter “thickness”
For instance, when connecting expandable connectors Dymola uses thickness=0.5, that means 0.5mm, which, on usual dpi’s is 2 pixels, i.e. twice the other connecting lines.

When reading models created by Dymola, OM does not honour this thickness and leaves also the connector-connecting (yellow) lines one-pixel wide.

MY PROPOSALS:

1) I propose to modify it so that the line thickness parameter is used in determination of actual line thickness.

2) Moreover, I propose to adopt Dymola’s technique, i.e. to use thickness=0.5 when connecting expandable connectors, since it makes clearer diagrams.

3) Point 1) should be applied considering actual logical DPI’s. For instance with 168 DPI (a win system with 175% magnification) lineThickness=0.25 implies two-pixel lines. This will be useful for 4k display systems

4) Finally, I propose use lineThickness=0.5 also when making array connections, i.e. "connect constructs referencing arrays of components (having size >1)” as they are defined in definitions and examples of sect. 9.1 of Modelica specifications.

Points 1) and 3) above are actions needed to comply with specifications; the other two imply, IMO, a significant enhancement of the quality of our drawings.
In case of need, I can supply screenshots graphically depicting what I mean.

Note that when I say that thickness=0.5 means 0.5 mm I refer to Modelica specifications 18.6.1 and 18.6.5.1. I assume that mm’s used in those specs refer to the logical DPI: 25mm=1in=96 pixels at 96DPI, so 0.25mm is one pixel at 96 DPI
