Kako povezati oblike sa konektorima u Javi

Konektori u Aspose.Slides FOSS su linijski oblici koji se pričvršćuju na mesta spajanja na drugim oblicima. Kada pomerite povezani oblik, krajnja tačka konektora se pomera zajedno sa njim. Najčešći tip konektora je BENT_CONNECTOR3, koji se zaobilaženjem prepreka kreće sa jednim laktastim savijanjem.

Granice rezervacije (0, 0, 10, 10) prosleđene u addConnector se ignorišu kada se postave krajnje tačke veze; PowerPoint preusmerava konektor na prikačene oblike.
