A colorName is a name from the color naming system in the Cedar ColorTool. may raise FontStringError Box Slices A box is a slice which maintains its rectilinear properties. It is possible to select/drag one of four corners, one of four edges, or the entire box. When a corner is dragged, box is rubberbanded to keep its box shape. When an edge is dragged, only the perpendicular component of the drag vector is used to move the edge, thus maintaining box shape. When the entire box is selected (traj or topLevel), it can be translated and rotated. transform defaults to the identity. Circle Slices Interpress Slices pixelsPerUnit explains what the unit was when the interpress master was made. The default value is for meters.
