Sets the width of a line, or retrieves its current width.

This function applies to the selected object, which is typically the last placed object. By using the PageSelectFirstObject() and PageSelectNextObject() functions, you can access your objects and change or read their properties.




A value between 0 and 32 representing the line width in pixels.

Return Value

If retrieving the current width of a line, a value between 1 and 32 (representing pixels) is returned. If setting the line width, 0 (zero) if successful. In both cases, an error is returned if unsuccessful. If values are out of range on writing to the attribute, the function will exit and report the error E_INVALIDARG. If there is no active object, they will exit and report a return value of E_HANDLE.

Note: For details on handling return and error values, see Error Handling.
