Déformation par "Cage"

[Bart Simpson]

Bonjour,
je souhaite poser une question sur l'outil de déformation par cage.
Mais avant d'aller plus loin et de poser ma question, je doit préciser que je suis français et que je ne parle pas anglais.
Aussi j'utilise le fonction de traduction automatique.
Et avant d'entamer la discussion je souhaite vérifier que le traducteur fonctionne et que vous recevez bien mon message en anglais.
La communication français/anglais est elle correcte?

Bien à vous, 
Bart

---------------
I would like to ask a question about the cage deformation tool.
But before going any further and asking my question, I must point out that I am French and do not speak English.
I am therefore using the automatic translation function.
And before starting the discussion, I would like to check that the translator is working and that you are receiving my message in English.
Is the French/English communication correct?

Kind regards,

I am sorry, I was thinking that I had 'atomatic translation' working to translate my messages into English. I am going to use a translator for the continuation.

Hello,
I come to ask you for help because I can’t use the tool 'deformation by cage' correctly on Gimp at all.

My project is yet simple:

1/ In image 1: we see the sail of a boat and a text (I took "fox and raven" for example = "Le corbeau et le renard").
The goal is to stick this text on the sail, and therefore to deform it in a rounded way to follow the convex curve of the sail. To give the impression that one has written directly on the fabric on the sail before it inflates.

   

2/ On image 2: I have drawn a red grid around the text, a forecast of the transformation cage in order to place its handles regularly according to parallel horizontal lines.
Then on the sail I traced color lines to have marks to follow when deforming the cage. These color lines are slightly radiating towards a point far to the right, like the spokes of a bicycle wheel.

   

3/ In image 3: I placed the framed text in its red grid on the sail. The text is pixelated of course. It is no longer strictly speaking 'of the text' but 'an image'.

   

4/ In image 4: I created a deformation cage around the pixelated text, placing the handles regularly thanks to the red grid.

   

5/ In image 5: I added the radiant color lines to guide my deformation.

   

6/ In image 6: I moved the handles of the cage to the ends of the radiating lines.
The result is: completely nonsense!
The lines of text being 'lines' should have remained 'lines' but positioned in a radiating manner in order to follow the guide lines. There is no reason for lines of text to become curved waves anyhow.
Even worse: the distorted pixelated text comes straight out of the cage at the top left ("the crow and the fox" = "Le corbeau et le renard" as well as the beginning of the first paragraph come out of the cage).
In addition, there is the top-left corner of the original undistorted text that has remained apparent, it is not serious, it can easily be erased). 
 
   

7-8/ Image 7 and 8: the final result is completely missed.

   

   

I imagined that the tool «deformation by cage» stuck the image on an elastic surface (like a balloon) that one could stretch at will to take another shape. But at this rate, pixelated text has no reason to leave the elastic surface.

I thought at first that my version of Gimp had a bug, that a virus had eaten a line of code from the software.
But I have 2 computers: a Mac and a PC on which I installed each its version of Gimp (Mac version and PC version, so 2 clearly different versions). I downloaded these versions of Gimp directly from the official website http://www.gimp. Then they are clean versions. 

It is therefore that I did not understand at all how the deformation cage is used.
Can you advise me on how to distort this text to stick it neatly on the sail?
I thank you for your help

Do not be too ambitious with the Cage Deform.  It does move pixels around and can wreck your text.

My thoughts: I hope you have the text "as text layer"

Split the text into sections.  Do some hard formatting with leading spaces. Then rotate the text according to your template.  That does lose the text properties.

   

If you want to try the cage deform, keep the number of nodes to minimum. Make minimum adjustment. It does alter the size of the pixels.

Yes, I do have the non-pixelated tetx layer text at source.
I am going to do some tests by cutting the ten small pieces.
Thank you
