DrawText improvements #30

Closed joreg closed 5 years ago

joreg commented 5 years ago

fails with empty text input
set default text input "vvvv"
the default position should be visible (now out of image topleft)
can the fontsize be in pixels?

the default position should be visible (now out of image topleft)

what would be a sensible default for this? are you suggesting default to be dynaimc based on image dimensions? also, how to distinguish default state form actual user input 0,0?

can the fontsize be in pixels?

seems like not according to this: https://docs.opencv.org/4.1.1/d6/d6e/group__imgproc__draw.html#ga5126f47f883d730f633d74f07456c576

i don't have a better idea than placing text at 100/100 so that it is most likely visible by default.

regarding size: ok, so be it then.
