pixFill

 pixFill
 is a subfunction of NetDraw for generating pixel data points
 based on the specified line width for reactions. 
 
 Inputs:
 I: An array containing the customized metabolic map.
 pixx, pixy: Reaction coordinates.
 ColSpec: Color code of the specified reaction.
 
 Outputs:
 I: Customized metabolic map after adjustments.
 pixx,pixy,pixx1,pixy1: Boundary pixel data based on the specified
 reactions' width.

0001 function [I,pixx,pixy,pixx1,pixy1] = pixFill(I,pixx,pixy,LineStrength,ColSpec)
