Dynamic Align Text to Curve { with Reactors }
« on: November 12, 2009, 08:16:53 AM »
I realise that I have laboured over the topic of aligning text to something - but I wanted to brush up on my knowledge of reactors and xData, so I have strived to create this program, which will align DText/MText to any Curve Object, and will re-align the text when the object is modified.

More as a learning exercise, but some of you may get some use out of it  8-)







Function Syntax:  DTCurve  /  DTRemove

Code: [Select]

;;                                                                               ;;
;;  The Program will prompt the user to either Select existing text to align,    ;;
;;  or specify New Text. The user will then be prompted to select a curve, and   ;;
;;  the text specified/selected will be dynamically aligned to the selected      ;;
;;  curve.                                                                       ;;

;;  Additionally, the user can press +/- to alter the text offset from the curve ;;
;;  and furthermore, toggle the text perpendicularity by pressing 'P' during     ;;
;;  text alignment. A Background Mask can be toggled by pressing 'B' when        ;;
;;  aligning MText. The Text can also be mirrored by pressing 'M' during text    ;;

[ Code Updated to Version 2.9 ]

Please Note:-
All text that has been aligned using previous Versions (pre V2.7 ) of this program will need to be re-aligned, use DTRemove, then DTCurve to re-align the text. This is due to a re-structuring of the xData stored in the object.


Code available here.

Moouuuaahh !!

we have same thing here..
the difference is the reactors...that we don't have.. ;-)

thanks for sharing Lee..  nice code !

Thanks Andrea.... I thought you may have had a similar program... that always seems to happen with us  :-P

I thing that we have same vision of the future ...that's cool..  but weird.. ;-)

one little bug for your application....it is not working on diffrent UCS.
maybe need to use some "trans" conversion...

;-)

Lee,
You still always amaze me .... :love:
When i use your dtcurve with the same text but align to new different object, the text is still affected to previous object. Is that a bug?

Lee, amazing code, now if I can just figure out how to add a background mask to the text, it would be perfect.

Thanks Guys  8-)

> Andrea - I hadn't really thought about the UCS yet - that comes next  ;-)

> M4rdy,

I had thought about this, and wasn't really sure how to proceed, currently the user can align the same text to two objects and the text will be aligned to the object that is updated last.

I could however implement some code that will remove the associativity from any object, when the user selects text that is already aligned.

I shall investigate with the next version :)

> cmwade77

I may include an extra option for a background mask, but I have never worked with them, so I shall have to experiment a bit. :P


Thanks for the comments guys, glad you all like the program,

Lee

O.k., I found the problem, the routine is inserting dtext, in order for the background mask to work it needs to be mtext, any way to get this change made? (I can set the background mask once it is).

Unfortunately wipeouts don't plot correctly on our plotters, so they are not an option.

Ok, I have updated the code in the first post to Version 1.1

In this version, I have fixed the bug that allowed a single text object to be aligned to multiple objects.

I have many many ideas for this program, but little time to work on them, so I shall update it when I can  :wink:  Keep your eyes peeled  8-)

Enjoy!

I have updated the code in the first post to Version 1.2  -  this version includes DTRemove a function to remove the text/object associativity.  8-)

Ok, I had a bit of time to work on it tonight, so I have updated the first post to Version 1.3, apologies for two updates in the same day.  :oops:

In this version, the user can align DText and MText.

I have also found a few bugs that I am working to resolve, but I wanted to release this asap, so that MText could be aligned  :wink:

As requested, I have added the ability to use a Background Mask with MText, and have updated the code in the first post to Version 1.4

Wow, your code is a lot shorter than what I had for adding background masking; however, I don't know enough about VLA stuff, so my question is: How would I go about enabling background masking by default?
