בדף הזה נסביר איך להוסיף תמונות למצגת קיימת ב-Google Slides. כשמוסיפים תמונה, צריך לספק ל-Google Slides API כתובת URL של התמונה שגלויה לכולם.
מידע על תמונות
תמונות ב-Slides API הן סוג של רכיב דף. כמו בכל רכיב דף, מצינים את המיקום והגודל החזותיים של התמונה באמצעות המאפיינים size ו-transform של PageElement.
למידע נוסף על בחירת הגודל והמיקום הנכונים של התמונה, ראו גודל ומיקום של צורות.
כדי להוסיף תמונה, משתמשים בשיטה CreateImageRequest.
התמונות צריכות להיות בגודל של עד 50MB, לא יכולות לחרוג מ-25 מגה-פיקסל וצריכות להיות באחד מהפורמטים הבאים: PNG, JPEG או GIF.
דוגמה
בדוגמה הזו נעשה שימוש ב-Slides API כדי להוסיף תמונה למצגת.
