Hi,
I have a set of layers I need to position in the image at precise (to the pixel) positions. I *know* I can move them using the move tool, but it is a real pain. I Have been searching for some dialog where I can say exactly where in the canvas (much bigger than the layers) I want to have the (e.g.) top left corner of the layer. I have seen the Layer->Transform->Offset menu, but this gives an offset for the content into the leayer, while I need to set the offset of the layer into the image. I know It must be available somewhere, but I can't find it! :(

Thanks for Your help! Mauro

You can move with move tool with keyboard for higher precision. Choose
layer with Page Up/Down key, press M and you can move chosen layer with
arrows keys by 1 pixel, or by 10 pixels with arrows keys, while holding
Shift button.

Thanks.
It helps.

I would be much happier if I could have some kind of feedback. E.g.: a box showing the position of the layer into the canvas.

I have to position a huge (>100) number of (partially overlapping) layers on a regular grid. The Layers come from a single huge image that has been cut and I want to reconstruct. Relying on the image itself for positioning leads to errord that sum up :( I know the single layers were taken 1553x1038 pixel apart (horizontalxvertical), so, having the offset, it would be trivial to position them precisely.

Any further idea??

Quoting Mauro Condarelli :

The following Script-fu will allow you to enter numerical offsets into
a dialog box. Script-fu is unable to provide a visual preview of the
result but perhaps this will suit your needs (you can UNDO the operation if the result is unsatisfactory).

Save the text below as a file named "layer-offset.scm" in your scripts
directory. The command will appear as "Script-Fu->Transform->Layer Offset".

THANKS!!!

Nice :)
.. since You seem so knowledgeable...

Is there a simple way to to make a dialog that does not change the values, but updates them when I move the layer?

Is this possible at all? I mean: is it possible for a dialog to react to changes made to the image? This seems to imply some kind of notification/callback mechanism that I don't know if it's implemented at all.

I *will* try to get info about the available functions in the docs, but a pointer would be welcome. :)
