making a 'spokes on a wheel' design |

EDIT - after posting, I realized I posted to the wrong forum. I'll try to contact the Admins to get it moved/removed.
Hi all, I'm using GIMP 2.10.8 on Mac 0S Sierra 10.12.2.
How can I create a series of lines that radiate from the canvas center, and mark out equal segments of a circle? (I've put in place a horizontal and vertical guide, with the snap to guides turned on)
I've drawn two line segments, one that crosses the center of the canvas, and one that begins in the center of the canvas. But the rotate tool is based on a point in the center of my line segment.
ps - there is a video that shows how to do something like this, but there is no sound (!) and my eyes aren't good enough to see what s/he is actually doing. (I hope in this case it's ok I'm posting a link, I think it's the best way to explain)

Thank you very much
Hikaru
(I have some experience using photoshop, and I've made a flyer and a business card so far with GIMP.)

individual canvas size for layers? |

I'm working on a huge (14'x8') image that I'm slicing down into individual standard US Letter size fragments. I need to export the layers created this way to a PDF with each layer as a page. When I do this, the individual pages it creates seem to keep the main canvas size of the huge image as the page size, rather than the boundary of each layer. Is there anything I can do to make each layer's boundary the size of its page in the PDF? I'd like to avoid having to manually crop each page, since there are 224 of them.
Thank you in advance!

Is there a way to automate file exports to make anim frames? |

Rather than creating multiple layers within GIMP to build animations with, I would like to be able to export multiple images with a naming system like sample_001.jpg, sample_002.jpg, sample_003.jpg etc. The idea being, that each one will be the same image with the same filter applied, but each export will slightly modify one (or more) of the filters attributes. For example, started with a normal image, and then on each export, applying a blur filter so that the first image is crystal clear, and the last image is max blur. To do this manually, I can apply the blur filter -> export -> undo blur -> re-apply blur with a more intense setting -> export -> undo blur -> and so on. Eventually having a folder of images with a "gradient" of blur applied to them collectively, which I can then import into a video editor to chain together.
I'm thinking I can use python for this, but haven't been able to find an example showing how that would be possible
I'm new to python-fu (and scheme, but I know python so I was hoping I could use it instead of scheme). Anyways, I was thinking it could have something to do with the process of selecting the "pdb.file_jpeg_save" plugin in the python-fu console, and creating a for loop or while loop so that I can save a file in each iteration using the string filename = "image" + increment_variable, and then also applying a filter and incrementing or decrementing a filter parameter too.
Are there any good tutorials that cover these types of specifics? Thanks in advance!

I saw the option " Heal Transparency " under the " Enhance " menu just near to " Heal selection ". I have used " Heal selection " option but not sure what is the use of " Heal Transparency " ? Any tips will be great. Thanks.
