How to Control the Size of a Symbol in JavaScript Diagram?

When configuring the SymbolPalette in the Syncfusion® JavaScript Diagram component, the symbolWidth and symbolHeight properties play a key role in defining the size of each symbol displayed in the palette. By setting these properties, you ensure all symbols are uniformly scaled to fit the specified dimensions, maintaining a consistent appearance across the palette.
However, if your design requirements call for symbols with varying dimensions, you can achieve this flexibility by omitting the symbolWidth and symbolHeight properties from the SymbolPalette configuration. Instead, you can specify individual width and height values directly within each symbol’s node definition.
This approach allows you to tailor the size of each symbol according to your specific layout needs, offering a more customized and dynamic presentation within your application.

{
   id: 'Terminator', addInfo: { tooltip: 'Terminator' }, width: 50, height: 60, shape: { type: 'Flow', shape: 'Terminator' }
},
{
   id: 'Process', addInfo: { tooltip: 'Process' }, width: 50, height: 60, shape: { type: 'Flow', shape: 'Process' }
},
{
   id: 'Decision', addInfo: { tooltip: 'Decision' }, width: 50, height: 60, shape: { type: 'Flow', shape: 'Decision' }
},
{
   id: 'Document', addInfo: { tooltip: 'Document' }, width: 50, height: 50, shape: { type: 'Flow', shape: 'Document' }
},
{
   id: 'PreDefinedProcess', addInfo: { tooltip: 'Predefined process' }, width: 50, height: 50, shape: { type: 'Flow', shape: 'PreDefinedProcess' }
},
{
   id: 'data', width: 50, height: 50, addInfo: { tooltip: 'Data' }, shape: { type: 'Flow', shape: 'Data' }
}, 

By using this method, you gain precise control over the size of each symbol, enhancing the visual diversity and adaptability of the SymbolPalette to meet the unique requirements of your application.
