Can I use AI image editing to remove objects or change colors in deck assets?▼

Yes, AI image editing can remove objects, change colors, and refine details in deck assets by sending the image path and a specific edit prompt to the Gemini API via a command-line script.

Do I need a GEMINI_API_KEY to apply AI image edits to MDX content?▼

Yes, applying AI image edits requires a GEMINI_API_KEY environment variable to authenticate your requests to the Gemini API when running the image editing CLI script.

How do I specify the output resolution and aspect ratio for AI image editing?▼

You specify the output resolution and aspect ratio for AI image editing by passing the optional --resolution and --aspect-ratio command-line arguments along with the --image and --prompt parameters.

Does AI image editing automatically update MDX references when saving to deck assets?▼
