Εργασία με Συνδέσμους — Aspose.Slides FOSS για Python

Οι συνδέσμοι είναι σχήματα που συνδέουν οπτικά δύο άλλα σχήματα με μια γραμμή. Aspose.Slides FOSS για Python υποστηρίζει λυγισμένους, ευθείς και καμπυλωτούς συνδέσμους. Τα σημεία σύνδεσης σε ένα σχήμα προσδιορίζονται από ακέραιο δείκτες θέσεων σύνδεσης.

Δείκτες Θέσεων Σύνδεσης

Κάθε σχήμα εκθέτει τέσσερις τυπικές θέσεις σύνδεσης:
