تعيين خيارات الصفحة مع JavaScript عبر C++

ضبط خيارات الصفحة

تدعم خيارات إعداد الصفحة بالكامل في Aspose.Cells. يشرح هذا المقال كيفية ضبط خيارات الصفحة مع Aspose.Cells ويعرض عينات الشفرة للضبط:

توفر Aspose.Cells فئة، Workbook، التي تمثل ملف Microsoft Excel. تحتوي فئة Workbook على مجموعة worksheets التي تتيح الوصول إلى كل ورقة عمل في ملف Excel. تمثل ورقة عمل بفئة Worksheet.

توفر فئة Worksheet الخاصية PageSetup التي تُستخدم لتعيين خيارات إعداد الصفحة لورقة العمل. في الواقع، هذه الخاصية PageSetup عبارة عن كائن من فئة PageSetup يُستخدم لتعيين خيارات تخطيط الصفحة المختلفة لورقة عمل مطبوعة. توفر فئة PageSetup خصائص مختلفة تُستخدم لتعيين إعدادات الصفحة. بعض هذه الخصائص مذكورة أدناه.

اتجاه الصفحة

يمكن تعيين اتجاه الصفحة إلى عمودي أو أفقي باستخدام الخاصية orientation من فئة PageSetup. تقبل الخاصية orientation إحدى القيم المعتمدة في تعداد PageOrientationType، المدرجة أدناه.

أنواع توجيه الصفحة الوصف
Landscape توجيه أفقي
Portrait توجيه عمودي
