تصف هذه الصفحة كيفية إضافة صور إلى عرض تقديمي حالي في العروض التقديمية من Google. عند إضافة صورة، عليك تزويد واجهة برمجة تطبيقات العروض التقديمية من Google بعنوان URL للصورة يمكن للجميع الوصول إليه.
لمحة عن الصور
الصور في واجهة برمجة تطبيقات العروض التقديمية هي نوع من عناصر الصفحة. كما هي الحال مع أي عنصر
صفحة، يمكنك تحديد الحجم المرئي للصورة وموضعها باستخدام السمتَين size
وtransform للسمتَين
PageElement.
للحصول على مزيد من التفاصيل حول كيفية تحديد حجم الصورة وتحديد موضعها بشكل صحيح، يمكنك الاطّلاع على حجم الأشكال وتحديد موضعها.
لإضافة صورة، استخدِم طريقة CreateImageRequest.
يجب ألا يزيد حجم الصور عن 50 ميغابايت، وألا يتجاوز 25 ميغابكسل، ويجب أن تكون بتنسيق PNG أو JPEG أو GIF.
مثال
يستخدم هذا المثال واجهة برمجة تطبيقات العروض التقديمية لإضافة صورة إلى عرض تقديمي.
