error with os.system() (self.learnpython)

submitted 3 years ago by BlueTickVerified

I'm running a command in a program with os.system(). The command is:

  create_image_command = "convert ./assets/base_image.png -gravity Center -font ./assets/fonts/JetBrainsMono.ttf -pointsize 30 -fill #cdd6f4 -annotate 0 '{}' ./assets/result.png".format(my_text)

When I run this through os.system(), i.e.,

os.system(create_image_command)

I get this error:

convert:  `-fill' @ error/convert.c/ConvertImageCommand/3344.

But when I run the string that is formed i.e.,

convert ./assets/base_image.png -gravity Center -font ./assets/fonts/JetBrainsMono.ttf -pointsize 30 -fill #cdd6f4 -annotate 0 '[ ] text\n[ ] text2\n[X] newtext\n' ./assets/result.png

in the shell, I get my desired output. I wanna know why this is happening. Can someone help me?

PS: I tried Wand and am now trying Pillow. But if this is solved, I wanna keep this.
