示例1: MolToImage

# 需要导入模块: from rdkit.Chem.Draw.MolDrawing import DrawingOptions [as 别名]
# 或者: from rdkit.Chem.Draw.MolDrawing.DrawingOptions import selectColor [as 别名]

  """Returns a PIL image containing a drawing of the molecule
    
      ARGUMENTS:

        - kekulize: run kekulization routine on input `mol` (default True)
        
        - size: final image size, in pixel (default (300,300))
        
        - wedgeBonds: draw wedge (stereo) bonds (default True)
        
        - highlightAtoms: list of atoms to highlight (default [])
        
        - highlightMap: dictionary of (atom, color) pairs (default None)

            use 'matplotlib.colors.to_rgb()' to convert string and
