Hi Prof,

Ejs 4.2 new text objects cannot display "^o" as subscript string, how to overcome ?

i am exploring to update to newer objects to submit the models i have made in projectile motion to http://www.compadre.org/

the codes is:

s_alpha =alphasymbol+"= "+double2String(theta,1.)+"^o" ; // to make display 2.30=vx instead of 2.3000000001

any idea how to display superscripts in Ejs 4.2 new text?

Please write down where is the code: which page/tab/...etc. so that I can find your code easily.
It seems to be a bug. I would suggest you to talk to Paco directly.
You can use two strings to display what you want (need to calculate coordinate properly).

thanks!

any idea how to display superscripts in Ejs 4.2 new text?
Text elements can only display superscripts (and subscripts) if the "Pixel Size" property is set to true. (The default is false.) The reason is that the underlying code uses some tricks with the fonts that produce the effect of superscripts. When drawing the text in world units (something that was not possible with old elements) the rendering cannot fulfill this requirement.
Solution: Set the "Pixel Size" property of text elements to true.
