GIMP Version: 2.9.1
Operating System: Linux
OS Version: Linux Mint 17.2
GIMP Experience: Basic Level

List any ERROR messages you received:
Error: Invalid number of arguments for gimp-image-select-item (expected 3 but received 1)

Hi again all,

Im attempting to update a small script from 2.8 to 2.9. Ive taken care of all the errors except the one listed above.

My issue stems from not knowing enough about script-fu to make the necessary change.
According to spec the gimp-image-select-item requires the following 3 parameters:
Image, Operation (int32), and Item.

In the script the function is written as

Code: Select all

(gimp-image-select-item varBlurredSelection)

Which parameter is the variable?

Thanks for any assistance on this.

In 2.8 and 2.9 this call to the PDB is the same (gimp-image-select-item image operation item)

Correct what I ment was which parameter was the "varBlurredSelection"?

The variable is the third parameter, 'item'. Whether the item is a layer, a layermask, a channel, or a path will determine how the selection is modified.

The second parameter, 'mode', determines whether the "item" gets added to, gets subtracted from, gets intersected with, or replaces the selection.

The first parameter is the ID of the image to which the item belongs.

Thank you Saul.
Is there a definitive source for learning script-fu?
