Hello Everyone,

Can anyone help me to save Individual plot images from WL test (Create a .png file from some of the analyzed images individually)? What code lines should i write to do it? I just can’t figure it out.

Thanks

Hi Bruno,

below a part of code I use to generate a jpg from a plot of WL profiles.

Some comments:

  • the part with plt.text it is used to superimpose results on the figure (https://matplotlib.org/3.1.1/api/_as_gen/matplotlib.pyplot.text.html)
  • the jpg name is composed by two parts, one is “field”, that is extracted from a TIFF file (such as gantry0.tif → field = gantry0) and the second is jpg, so that the jpg file is automatically called “gantry0.jpg” for example
  • I set width and height in order to have a specific image size
  • if you want another format you shall specify it in plt.savefig, but I think the default is png (to be checked).

You can take a look here for additional info: https://matplotlib.org/3.1.1/api/_as_gen/matplotlib.pyplot.savefig.html

I hope this can help you!

Regards,

Andrea
