Apply filters to images
With GemBox.Imaging, you can apply filters to images programmatically in C# and VB.NET, as shown in the following example.
using GemBox.Imaging;
class Program
{
static void Main()
{
// If using the Professional version, put your serial key below.
ComponentInfo.SetLicense("FREE-LIMITED-KEY");
using (var image = Image.Load("%InputFileName%"))
{
// Adjust blue channel and contrast of the image.
image.ApplyFilter(x => x
.Blue(50)
.Contrast(20)
);
// Save the adjusted image.
image.Save("Adjusted.png");
}
}
}Imports GemBox.Imaging
Module Program
Sub Main()
' If using the Professional version, put your serial key below.
ComponentInfo.SetLicense("FREE-LIMITED-KEY")
Using image As Image = image.Load("%InputFileName%")
' Adjust blue channel and contrast of the image.
image.ApplyFilter(
Function(x) x.Blue(50).Contrast(20))
' Save the adjusted image.
image.Save("Adjusted.png")
End Using
End Sub
End Module
