יצירת שקף

בדף הזה נסביר איך להוסיף שקפים למצגת קיימת ב-Google Slides.

מגלשות

כל דף בנפרד במצגת ב-Slides הוא שקף.

כדי להוסיף שקף למצגת, צריך את מזהה המצגת. כדי למצוא את המזהה של המצגת, פותחים אותה ב-Slides ומעיינים בכתובת ה-URL שלה:

https://docs.google.com/presentation/d/presentationID/edit

כדי להוסיף שקף, משתמשים ב-method‏ batchUpdate() עם מזהה המצגת, ומצרפים את ה-CreateSlideRequest לגוף הבקשה. המזהה של השקופית החדשה מוחזר בגוף התגובה.

דוגמה

הדוגמה הבאה מראה איך מוסיפים שקף למצגת. כל השדות של CreateSlideRequest הם אופציונליים. בדוגמה הזו, השקופית נוצרת כשקופית שנייה, עם פריסה TITLE_AND_TWO_COLUMNS ומזהה אובייקט מפורש.

אחרי שיוצרים את השקף, אפשר להוסיף לו טקסט וצורות.

מילוי placeholders

בדרך כלל, בפריסות יש צורות של placeholders שמועברות לשקופית בזמן היצירה שלה. בעזרת CreateSlideRequest אפשר לציין את מזהי האובייקטים שבהם נעשה שימוש ב-placeholders המועתקים האלה, דרך השדה placeholderIdMappings. כך תוכלו לשנות את placeholders שהועברו באותה בקשה batchUpdate, וכך לשפר את הביצועים ולחסוך במכסה. למידע נוסף, ראו הדוגמה CreateSlideRequest.
