The Image Widget is separate from the diagram widget and displays static images that can be changed based on certain conditions. These widgets act as narrative tools for end users to understand what is being designed and how inputs are expected to be used.
Images can also be added under widgets within the “Reference Image” section. Local files can be uploaded, but images from standards/references/guides should be avoided and should either be ignored or replicated.
Image Widget Example

​
Example Code

{
  "type": "sheetTemplateWidgets",
  "attributes": {
    "type": "image",
    "label": "",
    "visibleIf": "",
    "referenceId": "image",
    "equation": [
      {
        "condition": "@default",
        "result": "\"imageID1\""
      }
    ],
    "image": {
      "imageID1": {
        "inline": "insert data uri"
      }
    },
    "references": "",
    "description": "",
    "authorNotes": ""
  }
}

​
Parameters

​
type
string
required
Must be “image” - defines the widget type
​
label
string
The name of the image widget, appears as the widget label exposed to end users
​
visibleIf
string (equation)
default:"true"
An equation resulting in boolean true/false representing whether the field should be included in the sheet. If visibleIf==false, any fields referencing this field will error
​
referenceId
string
required
Unique reference ID of the image widget
​
equation
array
required
List of equation objects allowing images to be conditional on various events. The "result" must always point to the ID of images to be displayed when corresponding conditions are met
​
image
object
required
The image container containing a dictionary with image ID names as keys and actual images as data URIs. Data URI is placed as a value in the "inline" attribute
​
references
string
Standardized reference to the building code and major version from which the field is sourced/based upon
​
description
string
Minor explanation providing context, definitions, or clarifying information to the user about the field
​
authorNotes
string
Internal development notes never displayed to users

​
Image Configuration

​
Multiple Images

The image container can contain as many images as required by the equation: 
"image": {
  "imageID1": {
    "inline": "data:image/svg+xml;base64,..."
  },
  "imageID2": {
    "inline": "data:image/png;base64,..."
  },
  "imageID3": {
    "inline": "data:image/svg+xml;base64,..."
  }
}

​
Conditional Display

Use equations to show different images based on conditions: 
"equation": [
  {
    "condition": "input_type == 'beam'",
    "result": "\"beam_diagram\""
  },
  {
    "condition": "input_type == 'column'",
    "result": "\"column_diagram\""
  },
  {
    "condition": "@default",
    "result": "\"default_image\""
  }
]

​
Data URI Conversion

To convert an SVG or other image to a data URI, use any data URI converter such as duri.me.

​
Supported Formats

  • SVG: data:image/svg+xml;base64,...
  • PNG: data:image/png;base64,...
  • JPEG: data:image/jpeg;base64,...

​
Best Practices

Copyright Considerations: Images from standards/references/guides should be avoided and should either be ignored or replicated to avoid copyright issues.
  • Use descriptive image IDs that clearly indicate their purpose
  • Keep image file sizes reasonable for web performance
  • Provide alternative images for different input scenarios
  • Use SVG format when possible for scalability
  • Test image display across different screen sizes
  • Include relevant descriptions for accessibility

​
Common Use Cases

  • Load diagrams - Show different loading conditions
  • Cross-section views - Display section properties visually
  • Connection details - Illustrate connection types
  • Boundary conditions - Show support conditions
  • Material orientations - Display fiber directions or grain orientation
