Utility for automatic generation of fallback images for the creatives.
Fallback generator checks manifest.json for formats, generates a fallback image and saves it to a defined fallback path.
By default, the fallback generator will try to look for ./assets/logotype.png image and will use it in fallback.html for image generation.
If you specify a custom HTML-file path fallback generator will open your HTML-file, resize its viewport based on the defined formats and generate an image.
Just run npm run fallback inside the directory of creative.
Additional parameters can be added for the script using npm run fallback -- [flags]
Example:
npm run fallback -- -b 'red' This will change the background color to red.
