Možete umetnuti logotip, potpis ili bilo koju vizualnu informaciju kao slikovni vodeni žig u PowerPoint prezentaciju s jednostavnim API sučeljem u C++. Značajka ne ovisi o Microsoft PowerPointu ili bilo kojoj aplikaciji za dodavanje slikovnog vodenog žiga na Windows ili Linux platformama.
Koraci za dodavanje slikovnog vodenog žiga u PPTX koristeći C++
- Instalirajte Aspose.Slides for C++ iz alata NuGet Package Manager
- Dodajte referencu na imenski prostor Aspose::Slides
- Učitaj ulaz PPTX za dodavanje vodenog žiga slike koristeći Presentation Class
- Dodajte PictureFrame u sve glavne slajdove za dodavanje vodenog žiga na sliku
- Zaključajte vodeni žig dodane slike kako biste izbjegli promjene
- Spremite izlaznu PPTX prezentacijsku datoteku s vodenim žigom
Možete umetnuti slikovni vodeni žig u PowerPoint u C++ s nekoliko jednostavnih redaka koda. Ovaj primjer također je primjenjiv za PPT format datoteke.
