OffsetX Specifies the horizontal offset in pixels. This can have negative values
OffsetY Specifies the vertical offset in pixels. This can have negative values
channel The channel to shift: iecBlue, iecGreen or iecRed

ImageEnView1.IO.LoadFromFile( 'D:\TestImage.jpg' );


// Shift to -5 horizontally and -2 vertically in the Blue channel, filling new areas with 0
ImageEnView1.Proc.ShiftChannel( -5, -2, iecBlue, 0 );
