Hello


Is it possible to rotate a text with a angle [0 .. 360] with the possibility to continue to change it as a real field ?

Thanks for help

Hi fm31,

no, that is currently not possible, at least the editing.

You can get away with taking a snapshot of your text field and rotate (set the angle of img...)
the resulting image, but as I said, no more text editing in that case.


Best

thanks for answer

It's a stack example of rotating text.

thanks maxV
but this is an image of the text and it's not possible to modify it

Hm, didn't I tell you that this is not possible at all? See my first posting and read again!

Max is a nice guy but no magician!

@fm31 have another look at maxV's stack - there is a field as well as an image...

As dave.kilroy noted, you can modify the text clicking on it.

Could you explain what you did there? I need to be able to modify the text via a variable as well as the size and location.

There are 2 elements, the normal text field, and the image of it rotated.
The normal text field has this code:

########CODE#######
on Mouseleave
focus on nothing
send aggiorna to image uscita
set the visible of me to false
end mouseLeave
#####END OF CODE#####

the result image has this code:

########CODE#######
on aggiorna
export snapshot from rect (the rect of field ingresso) of this card to image uscita
set the angle of me to the tAngle of me
end aggiorna

on MouseUp
set the tAngle of me to the angle of me
set the loc of field ingresso to the loc of image uscita
set the visible of field ingresso to true
focus on field ingresso
end MouseUp
#####END OF CODE#####

It's a simple trick, you:

• lock the screen (this way the user will not notice anything untill unlock)
• modify the text
• make visible your normal field
• export as in image the normal field edited
• make invisible the normal field
• rotate the generated image
• unlock the screen

how is the image created/where did if come from?

Please read the thread, the magic word is "snapshot"!

The script instructs LiveCode to take a snapshot of the field thus:

If you spend time with the dictionary looking up key words you should find it easier to parse code samples on the forum...

EDIT: oops I see that Klaus answered this just before I did!
