Parameters in EPS, SVG and VRML Defaults Window


Window is divided into 5 frames, two on the left and three on the right. Note that settings you made in this window are overwritten if the parameters are specified in Pajek input (NET) file.

Top frame on the left - EPS/SVG Vertex Default

This frame defines default drawing of vertices when we export layouts to EPS and SVG:
  • Interior Color - interior color of vertices (see Crayola.pdf). If drawing using Partition is used, partition colors will overwrite interior color.
  • Border Color - color of the borderline of vertices (see Crayola.pdf)
  • Label Color - color of label of vertices (see Crayola.pdf)
  • Border Width - width of the borderline of vertex
  • Label Position: Radius /Angle - position where the label will be displayed:
    • Radius - distance of beginning of vertex label from vertex center - first polar parameter
    • Angle - position of vertex label in degrees - second polar parameter (0..360)
      If radius is equal to 0, the label will be centered, otherwise it will be aligned on the specified position to the left.
  • Fontsize - size of font for vertices labels
  • Label Angle - angle in which vertex labels will be displayed:
    if angle is smaller than 360, it means relative according to horizontal line (0 - horizontally);
    otherwise it is relative to center of the layout - useful when all vertices are drawn in concentric circle(s) (360 - concentrically)
  • x/y Ratio - ratio between size of vertex in x and y direction
  • Shape - default shape of vertex (Ellipse, Box, or Diamond)

Bottom frame on the left - EPS/SVG Line Default

This frame defines default drawing of lines when we export layouts to EPS and SVG:
  • Edge Color - color of edges (see Crayola.pdf)
  • Edge Width - width of edges
  • Arc Color - color of arcs (see Crayola.pdf)
  • Arc Width - width of arcs
  • Pattern - pattern for drawing lines (Solid or Dots)
  • Arrow Size - size of arrows when drawing arcs
  • Arrow Position - distance of arrow from terminal vertex: If distance is between 0 and 1, it means relative distance according to arc length, e.g.:
    0 - arrow just at the terminal vertex
    0.5 - arrow in the middle of the arc
    If distance is larger than 1 it means absolute distance from the terminal vertex (this is useful if you want to have all arcs on the same distance from terminal vertex, regardless of arcs length)
  • Label Color - color of line labels (see Crayola.pdf)
  • Label Position - position of the center of line label - position is point on the line - distance of the center of line label from terminal vertex (see also Arrow Position)
  • Label Position: Radius /Angle - position where the center of line label will be displayed according (relative) to Label Position:
    • Radius - distance of center of line label from point defined by Label Position - first polar parameter
    • Angle - position of label in degrees - second polar parameter (0..360)
  • Fontsize - size of font for line labels
  • Label Angle - angle in which label of line will be displayed:
    if angle is smaller than 360, it means relative to direction of line (0 - parallel to line);
    otherwise it is relative to horizontal line (360 - horizontally)

Top frame on the right

This frame defines some additional defaults when we export layouts to VRML:
  • EPS, SVG, VRML Size of Vertices - default size of vertices when exporting to VRML (valid for EPS and SVG exports as well)
  • VRML Size of Lines - width of lines in VRML
  • VRML Bckg. Color - background color of layout in VRML (see Crayola.pdf)

Middle frame on the right

This frame defines some additional defaults when we export layouts to EPS:
  • Add. Border (Right, Left, Top, Bottom) - additional border around layout when exporting to EPS (only when EPS Clip format is selected)
  • Background Border:
    • Bckg. Color - color of background (see Crayola.pdf). It is used for export to SVG as well.
      No - means without background color.
    • Border Color - color of borderline of layout (see Crayola.pdf). It is used for export to SVG as well.
      No - means without borderline.
    • Border Radius - radius of borderline of layout (if greater than 0 it means oval instead of rectangle)
    • Border Width - width of borderline of layout
  • Shapes file - default shapes file, double click to change it

Bottom frame on the right - SVG Default

This frame defines additional defaults when we export layouts to SVG:
  • Bckg. Color 2 - the second color for SVG export (see Crayola.pdf). First color is specified in the middle frame.
    No - means without second color, otherwise selected gradient will be used
  • Bckg. Color 3 - the third color for SVG export - gradient (see Crayola.pdf).
  • 3D Effect on Vertices - if selected, gradient will be applied to get 3D look of vertices
  • Gradients - type of gradient to use (No, Linear, or Radial)
