Alpha in color

Hi, is it possible to define the alpha value in a RgbColor in order to make it more or less transparant?

Hello,

It is not possible to define alpha value in RgbColor class to make the color transparent. If you are looking to set transparency to the contents being added to the PDF then you can use TransperencyGroup class to do this. You will need to create TransparencyGroup class object by setting desired alpha value. Add the page elements to the TransparencyGroup object. Then add this object to page of PDF. You can refer to the documentation on TransparencyGroup here.
