تحويل الرسوم البيانية إلى صور

الرسوم البيانية جذابة بصرياً وتجعل من السهل بالنسبة للمستخدمين رؤية المقارنات والنماذج والاتجاهات في البيانات. على سبيل المثال، بدلاً من الحاجة إلى تحليل عدة أعمدة من الأرقام في ورقة العمل، يمكنك رؤية على الفور ما إذا كانت المبيعات تتراجع أم ترتفع على مدى فترات الربع، أو كيف تقارن المبيعات الفعلية بالمبيعات المتوقعة. في بعض الأحيان، قد تحتاج إلى عرض الرسم البياني في تطبيقاتك أو صفحات الويب الخاصة بك. قد تحتاج إلى إدراجه في مستند Word، ملف PDF، عرض PowerPoint أو في سيناريو آخر ما. ببساطة ترغب في أن يتم عرض الرسم البياني كصورة، بحيث يمكنك لصقه في تطبيقاتك بسهولة. الصورة تستحق. في كثير من الأحيان، في مجرى العمل، يجب على الشخص عرض المعلومات الإحصائية والرسومية بطريقة سهلة الفهم وسهلة الصيانة. قد تجرب Office Automation ولكن Office Automation تحتوي على عيوبها الخاصة. هناك عدة أسباب وقضايا تتعلق بها: على سبيل المثال، الأمان، الاستقرار، القابلية للتوسيع/السرعة، السعر، الميزات وما إلى ذلك. باختصار، هناك العديد من الأسباب، والأهم منها هو أن شركة Microsoft نفسها توصي بشدة بعدم استخدام Office automation من حلول البرمجيات: الاعتبارات لأتمتة Office على الخادم. هناك خيار آخر يمكنك استخدامه لتحويل رسم بياني Excel إلى صورة باستخدام Aspose.Cells.
