U ovom primjeru s uputama, provest ćemo vas kroz korake za dodavanje vodenog žiga u TIFF koristeći C#. Vrlo je jednostavno umetnuti vodeni žig u TIFF koristeći C# izvođenjem nekoliko API poziva.
Koraci za umetanje Tiff vodenog žiga pomoću C#
- Instalirajte Aspose.Imaging for .NET NuGet paket
- Uključi Aspose.Imaging, Aspose.Imaging.ImageOptions i Aspose.Imaging.Brushes prostore imena
- Koristite metodu Image.Load za učitavanje Tiff-a i dodavanje Tiff vodenog žiga
- Instancirajte objekte klasa Graphics, Font, SolidBrush i StringFormat da postavite font, boju i tekstualna svojstva vodenog žiga
- Upotrebom objekta klase Graphics zaštitite Tiff vodenim žigom u C#
- Spremite izlaznu sliku s Tiff vodenim žigom
U prethodno spomenutim koracima prvo smo učitali Tiff sliku u memoriju koristeći Load metodu klase Image. Zatim smo odredili atribute za oblikovanje fonta, kista i teksta kako bismo zaštitili Tiff vodenim žigom u C#. Na kraju, spremamo Tiff vodeni žig koristeći C#.
