If change the Global.ink color ( trying change the ink color dynamically ) causes removing previous annotations added using with same ink.

you should save actual annotation before changing new drawing parameters.

May you put your code snippet, please?

Note: what's the platform you are working on?

Please, submit posts in the proper forum area.

My platform is : Android

Here is the code am using to change the color of the ink.

Global.inkColor = color;
if(m_ink != null)
{
m_status = STA_INK;
if(m_status == STA_INK) {
m_ink = new Ink(Global.inkWidth);
}
}

Here i thought to change the color parameter of the ink object, but color change is not worked. so I re instantiate the ink object.
