Curving an image
What are the best ways to take an image of a straight line and bend it into an s-curve with The GIMP? I have tried the perspective and shear tools as well as the distort->curve bend filter without producing an ideal result.
Are there other options? I'd like to be able to set some points and pull them around with the mouse similar to the UI for the path tool.
Thanks,
Barton

i have had limited success with Filters -->Map -->Map Object.
you can play with all sorts of variables, in the dialogs and also with the image you are mapping.
both the cylinder and the sphere do some interesting curving.
it is a plug-in that you must be patient with and try a lot of different things with. it is also the only plug-in that i pushed my "Reset all Plug-Ins" option for as it does not (yet) have its own reset button.
it has recently been crashing on Map to Box when you move it along the z axis, but not everyone has been able to reproduce this crash.
notice and play with the tabs. give the plug-in what it wants. it will not give you what you wanted, but the result is not bad and you can try it again giving it more or less space.
or you can brush up on your polar coordinate options and use Filter -->Distorts -->Polar Coords. i didnt like these in mathematics and i am not so good with them in graphical design either.
i hope this helps, carol

In a word: iwarp .
Search for the iwarp filter in the Distorts menu - that is your man.

Heh...I gave a lecture on the GIMP yesterday. Just I had a computer and about 50 people watching - I will never forget their faces when I hit map to object -> map to box, and it started rendering in a way that would take about 2 minutes to complete, and, in the mean time, I just went on using the program, showing the other filters in the menus, as if the program were idle!!!!

Huh, I tried the Iwarp filter but it seems to be broken (GIMP 2.0.4 from the FC2 rpm).
It showed the layer in the preview window but regardless of any changes in parameters it didn't alter the image at all. Did I miss something, is this a known problem or a mystery?

You missed the fact that you need to manipulate the preview by clicking and dragging it. It isn't easily discoverable, I admit. Patches to improve this or contributions to the help are of course appreciated.

I was wondering whether the parameters were unnecessarily vague or I was just failing to grok the filter. Just now gave it a whirl and it is the filter for the task.
You're probably way ahead of me on this but wouldn't a larger preview window and an expanded UI (e.g., like the path tool) be great with Iwarp? Maybe implementing it as a tool rather than a filter would be in order as well?
Regardless, I've been doing some real work (TM) with The GIMP lately and I'd like to say thanks for the excellent app and all of the effort that goes into creating it, thanks a lot.
Ciao,
Barton

Sure, noone would disagree that the plug-in urgently needs some love. But so far noone has taken responsibility for it. There are a lot of plug-ins that are part of the distribution but are basically unmaintained. We don't have enough developer resources to work on the core and improve the ~ 200 plug-ins in the GIMP tree.
As I said already, if you want to contribute, please do so. You wouldn't have to necessarily write code. The GIMP help team (the people working on the user manual) are looking for contributors as well as the GIMP web team.

Heh heh. I fully appreciate your point and understand what it means for a project on the scale of The GIMP to be brought into the world by volunteers. I hope that the understanding is reciprocated in that my comments shouldn't be taken as implying dissatisfaction with the developers' efforts or any kind of demand for a specific feature to be implemented. Just casual commentary to be taken for what its worth.

Other than a little photo cropping, the last few days have been the first opportunity I've had to do any significant gimping. To this point I've been contributing by not messing up the works with my ignorance of digital image manipulation in general or of The GIMP in particular.
With a little bit of experience I may actually have something worthwhile to contribute so I'll check into the documentation project in the near future.
Regards,
Barton

If the cursor changed to a brush or something on mouseover of the preview it might help improve discovery. I assume it would be difficult to do but I'm pretty sure having Warp as a generic tool would please some users very much.

It does that in GIMP 2.2.
