How to prevent preview render and background render

[xaoc]

I'm blocking preview render and background render following way:

EffectPluginConfigDialog.cs :

private void buttonOK_Click(object sender, EventArgs e)
       {
           ((EffectPluginConfigToken)EffectToken).ButtonOKPressed = ButtonOKPressed = true;
           FinishTokenUpdate();
           DialogResult = DialogResult.OK;
           this.Close();
       }

EffectPlugin.cs :

bool locked = false;
       public override void Render(EffectConfigToken parameters, RenderArgs dstArgs, RenderArgs srcArgs, Rectangle[] rois, int startIndex, int length)
       {       
           EffectPluginConfigToken castedParams = (EffectPluginConfigToken)parameters;

           //here I block preview render
           if (!castedParams.ButtonOKPressed)
           {
               return;
           }

           //here I block  background render
           if (locked) return;
           locked = true;
           ..........
       }

My effect algoritm works on whole image so there is no reson to render in parts. I'm looking for

the propriate way to get the same result, that make the code given above.

This isn't a supported scenario at all. You're doing something the effect system isn't meant to be used for.

Thus, we can't really help you. Sorry.
