عرض شبكة صلبة أثناء تحويل Excel إلى PDF باستخدام JavaScript عبر C++

للتوافق مع الإصدارات القديمة، تقوم Aspose.Cells بشكل افتراضي برسم خطوط الشبكة كنقطة أثناء تحويل إكسيل إلى PDF. ومع ذلك، يعرّف إكسيل الحديثة خطوط الشبكة كخطوط صلبة اليوم.

باستخدام الخيار PdfSaveOptions.gridlineTypes، يمكن لـ Aspose.Cells for JavaScript عبر C++ أيضًا عرض خطوط الشبكة كخطوط صلبة.
