ImageElement

{
  "id": "image_001",
  "type": "image",
  "left": 100,
  "top": 150,
  "width": 400,
  "height": 300,
  "src": "img_1",
  "fixedRatio": true
}

Required Fields: id, type, left, top, width, height, src (source image ID like "img_1"), fixedRatio (always true)

Source Image Sizing Rules (keep original aspect ratio):

• src must be an image ID from the assigned media list (for example, "img_1"). Do not use URLs or invented IDs
• If no suitable source image exists, do not create image elements; use text and shapes only
• When dimensions are provided (for example, "img_1: 884x424, ratio 2.08"):
• Choose a width based on layout needs, typically 300-500px
• Calculate height = width / aspect_ratio
• Example: ratio 2.08, width 400 -> height = 400 / 2.08 ~= 192
• When dimensions are not provided, use 4:3 default (width:height ~= 1.33)
• Ensure the image stays within canvas margins (50px from each edge)
