This is the first workflow I am sharing. I did not create this workflow. I added nodes and organized it to suit my needs. I use it to recreate, or reformat vertical images into landscape or visa versa . It has options for cropping and a variety of options for filling in the additional space on the sides or the top. There are four options for creating new material for the sides or top. The first combines prompts from Joycaption and Image Interrogator. The second is a prompt from Joycaption, the third a prompt form Image Interrogator and the fourth is a custom prompt. The image of the workflow has the workflow embedded. Just drop in or import to Comfy. If any nodes have red outlines. Go to the manager and click install missing nodes. There is nothing complicated to install. Happy to answer questions. But I am not very experienced, so I can only offer limited assistance. I hope this helps someone, as this community has helped me so often.
