anybody knows how you can draw with arrays? i have two arrays, the x and the y coordinates.
i do: d.ImageDraw.Draw(im) d.point(E[0],E[1]) im.show() i get this error: only length-1 arrays can be converted to python scalars 2010/4/8 ioannis syntychakis <ioanni...@gmail.com> > thanks for all your answers. > Now i can get al the values above the 150, but i would also like to have > their positions in de matrix. > > excample: > > [[1. 4. 5. 6. 7. 1 > 2. 5. 7. 8. 9. 3 > 3. 5. 7. 1. 3. 7]] > > so, if i now look for values above the 8. the ouput should be; 1 value on > position (4,1) (beginnning from 0) > > is this possible? thanks in advance!!! > 2010/4/7 Ian Mallett <geometr...@gmail.com> > >> On Wed, Apr 7, 2010 at 7:40 AM, ioannis syntychakis < >> ioanni...@gmail.com> wrote: >> >>> Hallo Everybody, >>> >>> I am new in this mail list and python.
