Sets the image of an item symbol.
If you want to use a picture to set the symbol, use the Picture to Pixmap VI to convert the data to an image data cluster before using this method. The image cluster you wire to this method is similar to the image data input of the Write JPEG File, Write PNG File, and Write BMP File VIs.
Parameters
| Name | Data type | Required | Description |
|---|---|---|---|
| Index |  |
Yes | The index of the symbol you want to set. The default is 0. You also can wire a listbox symbol ring constant to this parameter to select the custom item symbol you want to replace with a default item symbol. |
| Image |  |
Yes | Describes the image you want to use for the item symbol. Images that are less than or equal to 16 × 16 pixels appear as their actual size. If you use an image that is larger than 16 × 16 pixels, LabVIEW shrinks the image to 16 × 16 pixels before displaying it as a tree control item symbol. |
