Hi all,
I’m developing an application with the ui
module, but have realised something that I’m not sure is either intentional or just overlooked; background_color
can be animated, whilst text_color
can’t.
Here’s an example. You can see that the text colour-changing is out of sync with the smooth background. The text changes to contrast with the background at the time.
Here is my code for the colour-changing functionality:
while True:
r = lambda: random.randint(0, 255)
colour = '%02X%02X%02X' % (r(), r(), r())
def determine_colour2(colour):
(r, g, b) = (colour[:2], colour[2:4], colour[4:])
# This next bit is pretty complicated, but its basically just an algorithm to find out what colour is needed for text
if 1 - (int(r, 16) * 0.299 + int(g, 16) * 0.587 + int(b, 16) * 0.114) / 255 < 0.5:
return '333333'
else:
return 'efefef'
colour2 = determine_colour2(colour)
def animation():
v.background_color = colour
v['chrome']['logo'].text_color = colour2
ui.animate(animation, duration = 3)
time.sleep(3)
If anyone can let me know if I’m doing something wrong or if this functionality isn’t implemented into Pythonista at all, it would be appreciated. Thanks!
