Description
Select a supplied portion-reference image ID by a one-based index.
Dietary arithmetic depends on as-purchased versus edible mass, per-serving versus per-100-gram bases, measured versus trace states and recall periods. A recorded allergen list is not a verified allergen-free declaration. Portion counts, label intervals and mass differences use supplied assumptions rather than establishing actual intake or nutritional suitability.
Select a supplied portion-reference image ID by a one-based index.
When to use this tool
Use Menu Portion Reference Image Index when you already have imageIds, indexOneBased and need to select a supplied portion-reference image ID by a one-based index.
How to use the tool and how it works
- Enter imageIds, indexOneBased. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read selectedImageId. Use the output convention below.
Require indexOneBased a safe integer in [1,imageIds.length]; return the corresponding ID.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| imageIds | Image Ids | Required. Array of text; maximum UTF-16 length 8192; maximum items 256. |
| indexOneBased | Index One Based | Required. Safe integer; minimum 1. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| selectedImageId | Selected Image Id | Required. Text; maximum UTF-16 length 8192. |

},
"output": {

}Limitations and assumptions
- IDs can be empty or repeated; an empty list has no valid selection. No image is loaded, portion estimated or suitable serving identified.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Check original food labels, composition sources, ingredient/allergen information and dietary records before combining amounts. Use a complete appropriately interpreted dietary assessment when requirements or suitable intake matter; local scaling and source labels do not make those judgments.
