schemedraw graph customize for png output file

Question

I would like to customize the graph:

How can I increase the output png resolution?
How to change the border color only? I do not want to change label color.
How to adjust box width automatically? box E’s text output the border now.


import schemdraw
from schemdraw import flow

def main(pngname):
    schemdraw.theme('dark')
    d = schemdraw.Drawing()    
    d += flow.Start().color('red').label('AAA')
    d += flow.Arrow().down(d.unit/2)
    d += flow.Box(h=1).label('BBB')    
    d += flow.Arrow().down(d.unit/2)
    d += (A := flow.Box(h=1,fill='#acacac').label('CCC'))    
    d += flow.Arrow().right(d.unit/2).at(A.E)
    d += flow.Box(h=1).label('DDDD')    
    d += flow.Arrow().right(d.unit/2)
    d += flow.Box(w=4,h=1).label('EEEEEEEEEEEEEEEEE')    
    d += flow.Arrow().right(d.unit/2)
    d += flow.Box(h=1).label('F')    

    d.draw()
    d.save(pngname)
    return

pngname = 'demo.png'
main(pngname)

Output resolution:

d.save(fname=pngname, dpi=some_num)

Change label color only:
This isn’t possible at the moment.

Box width automatically:
Set box width to be a multiple of label length len(your_label)*some_value
