Re: Scripting-Questions

 Hi Oliver,

1) Insert a layer at lowest position...
The image.add_layer method position argument is what you need to specify. 0 places a new layer at the top, 1 would be under the first layer, 2 under the second layer, etc...
image.layers give you the list of layers in the image. Use len(image.layers) to place it at the bottom...
   
Console example:
>>> # Get Active Image
>>> image = gimp.image_list()[0]
>>>
>>> # Create a new layer
>>> new_layer = gimp.Layer(image, "My New Layer", image.width, image.height, RGBA_IMAGE,100, NORMAL_MODE)
>>>
>>> # Add Layer Lowest Position
>>> image.add_layer(new_layer, len(image.layers))


2) Fit canvas to layers
You'll want to use: gimp-image-resize-to-layers

Console:
>>> image = gimp.image_list()[0]
>>> pdb.gimp_image_resize_to_layers(image)

3) The current documentation at http://www.gimp.org/docs/python/index.html and the pdb is about the best we gimp-python users have. There are a few sites out there with some posts, but everything is pretty dated. I'm currently picking away at a full tutorial and complete updated reference which I'll post here when I get it completed. I'm about 75% completed with it.

1)   <image>.add-layer: how can I insert at the lowest position?

2)   how can I script "Fit canvas to layers"?

3)   gimp.* / pdb.* and so on: which names using for Python, when 
     looking at the procedure browser?

     For example: i could not find out, how to call
     gimp-file-load-layer
     I tried with gimp.*  with pdb.*  without that also


The procedure browser seems to be good for scheme-users,
but for Python this is just a hint, and needs permanently
dabbling around.


Where can I find better documentatoion for Python-scripting?


Ciao,
