Wikivoyage volunteers need to create banners to place at the top of each article. Thousands of banners like this one:
Here is the process for each locality in the world:
- Example of locality: New York City
- Click on the Wikimedia Commons link on the left
- Filter out all images whose width is less than 2100 pixels
- Select the greatest remaining picture
- Select a 2100x300 area within that picture
- Save it as a new picture
- Upload that picture to Wikimedia Commons, with the same license as the original, and using the {{Image extracted}} template
- Set this picture as the banner property of the article's Wikidata item
A webapp that would help with all of that would be wonderful.
At least, are there tools that can help with a few of the steps?
- The only steps where a human is needed are 4 and 5.
- At step 5, it would be great if the 2100x300 shape was enforced when selecting. Or even better, if the tool allowed a larger selection, but enforced the same ratio (banner must be 2100x300 or bigger with the same ratio)
- Extra bonus for the ability to rotate the picture before cropping
- The best is webapps, but I am OK with software for any operating system.
