Hi,
I see lots of combinations when clearing the display during onUpdate. for example:
dc.setColor(Graphics.COLOR_BLACK, Graphics.COLOR_BLACK);
dc.clear();
dc.setColor(Graphics.COLOR_WHITE, Graphics.COLOR_TRANSPARENT);
If I want white text on a black barckground, what is the best combination in terms of performance/minimal battery use?
Thanks!
the clear only uses the background color so you could optimize the 3 statements to 2 for your use case:
dc.setColor(Graphics.COLOR_WHITE, Graphics.COLOR_BLACK);
dc.clear();
The the call to dc.clear() is by far (orders of magnitude) more expensive (processor/battery usage) than an extra call to setColor().
indeed, and if he needs the transparent background afterwards, then he'll anyway have to call it again.
