Finding Coordinates of Reference Points with (Android) Photo Editor (Macgyver)

[no need to use the steps on this blog as Hirota San has built in a calibration program in the latest version.  See the demo mentioned on Play store] 

Thanks Yochi Hirota for his great Apps
(Misphere Converter), and Jānis Bertrands for the generous finding the correct points and compiled a calib.txt for me, and both for showing us how to do it using Windows Paintbrush (finding coordinates of the reference point).

Below shows how to use Android Apps to find the coordinates
(Photo Editor (Macgyver) >Crop function)
and
save it to calib.txt
(Simple Text Editor)

PHOTO EDITOR> CROP

Use upper left corner as the pointer and read the left coordinates, scren capture for easy recall

 

SIMPLE TEXT EDITOR 

KEY IN THE NUMBERS, SEPARATED BY A SPACE, LEFT THEN RIGHT, NEW LINE FOR TGE NEXT PAIR

SAVE AS calib.txt AND COPY INTO MISPHERE CONVERTER FOLDER.

SHARE THE PHOTO TO MISPHERE CONVERTER
