Sådan forbinder du former med forbindelseslinjer i Python

Connectors i Aspose.Slides FOSS er linjefigurer, der fastgøres til connection sites på andre figurer. Når du flytter en forbundet figur, flytter connector endpoint sig med den. Den mest almindelige connector type er BENT_CONNECTOR3, som navigerer omkring forhindringer med en enkelt albuebøjning.

Pladsholdergrænserne (0, 0, 10, 10), der sendes til add_connector, ignoreres, når tilslutningsendepunkterne er indstillet; PowerPoint omdirigerer forbindelseslinjen til de vedhæftede former.
