Edge Source|Target Arrow Size?

[Paul Shannon]

This visual property does not seem to be in the vizmapper GUI, nor among

ENUM cytoscape.visual.VisualPropertyType:

EDGE_SRCARROW
EDGE_SRCARROW_COLOR
EDGE_SRCARROW_OPACITY
EDGE_SRCARROW_SHAPE
EDGE_TGTARROW
EDGE_TGTARROW_COLOR
EDGE_TGTARROW_OPACITY
EDGE_TGTARROW_SHAPE

And it is not among the values returned by CytoscapeRPC's "getVisualStyleModifiables"

Is it possible to change edge arrow sizes? (Am I overlooking something obvious?)

Thanks!

No, there's is no way to directly set arrow size. It would be
possible to add if people think it would be useful.

Hi Mike,

Speaking selfishly, I would find it very useful! I am preparing a small network from TCGA data for the RCytoscape paper. I fiddle with vizmap properties so that the network will look good on paper. Edge line widths and node fonts are fairly big. The source and target arrows are practically invisible. If I could make them as larger, proportionally, as the edge line widths, and do so programmatically (or through the vizmap bypass, or the vizmapper), I would not have to paste in a bunch of edge arrows in Illustrator.

I will completely understand, however, if you have other priorities.

Cheers!
