Lägg till bildhyperlänkar

Contents
[ ]

Aspose.Cells for JavaScript via C++ tillåter dig att lägga till hyperlänkar till bilder i kalkylblad vid körning. Det är möjligt att ställa in och ändra länkens skärm tips och adress. Följande exempel visar hur man lägger till en bildhyperlänk i ett kalkylblad.
