I'm new to gimp. I am having a problem with my rotate tool. It will not rotate. I know I am on the right layer. Searched google etc. Been looking for answers for a couple of days. The curser with the rotate symbol as a little circle with a line going through it witch, I believe is a lockout. Please take it easy on thee gimp terms. Can you help?
Thanks

| Removing Alpha Channel? |
|

I have been trying to write a script to automate colour cast removal.
If an image has transparency it "dilutes" the colour cast I am trying to remove.
When I run the following code
Code:
layerClean = pdb.gimp_layer_new_from_drawable(layer, image) # layer to be cleaned of alpha channel
pdb.gimp_image_insert_layer(image, layerClean, None, 0) # insert layer
pdb.gimp_image_set_component_visible(image, CHANNEL_ALPHA, FALSE) # make alpha channel non-visible
pdb.gimp_layer_flatten(layer) # remove alpha channel
pdb.gimp_image_remove_layer(image, layerClean)
I can look in the channels palette and the alpha channel has gone. In the layers palette I can right-click on the layer and it gives me the option to add an alpha channel. However, if I carry out any action, such as adding a layer, the alpha channel re-appears in the channel palette.
I have tried running the code and then doing a "Save as". On loading the saved file, the alpha channel is again in the layers palette.
I created an xcf file where the alpha channel was filled with 50% grey (7f7f7f Hex) in order to test.
I put this into general queries as the same occurs when the actions are carried out manually.

I have successfully written a script, which when ran in the Python-Fu console does what I want. I want to make a keyboard shortcut, so I can run this quickly when necessary, rather than pasting it into the console every time. How should I do this? I've tried writing the code in VS code and saving it in the GIMP scripts folder as both a .py and .scm file. The .scm file raises 'unbound variable: import' when I hit 'refresh scripts' under Script-Fu. I cannot find where to run the script as a .py, but it seems to refresh fine. I also do not know how I would bind a keyboard shortcut to a script.
Here's the code, though I doubt this is the issue as it works fine in the console:
import gimpfu
current_image = gimp.image_list()[0]
layer=pdb.gimp_layer_new(current_image, 1, 1, gimpfu.RGB_IMAGE, "white_layer", 100, gimpfu.NORMAL_MODE)
pdb.gimp_image_add_layer(current_image, layer, 0)
pdb.gimp_layer_resize_to_image_size(layer)
pdb.gimp_item_set_visible(layer, 0)

GIMP 2.10.32 was working perfectly. All of a sudden I can't export a head without a black background. I removed GIMP and re-installed. No difference. I'm stumped.

| middle of text layer to guide |

To align the middle of different text layers on different guides (vertical or/and horizontal), press Ctrl and Alt with 'Text Tool' activated, click in a text layer and drag it to a guide or a point where guides intersect. While pressing Ctrl and Alt a little cross appears in the middle of the text layer. This cross snaps to the guides. If the text box has an odd width, then the cross snaps one pixel left or right of the guide. Helps to make a personal time table for street theatre on different places and times for example.
