hello, I'm using PDF viewing with ImagenEnView and when scrolling the pages with the mouse wheel the pages run very quickly, how do I solve this?

Hi,

you may try TIEMouseWheelParams.Variation to limit the speed.

// Mouse wheel will scroll image by 15% of component height
ImageEnView1.MouseWheelParams.Action := iemwVScroll;
ImageEnView1.MouseWheelParams.Variation := iemwPercentage;
ImageEnView1.MouseWheelParams.value := 15;

// Mouse wheel will scroll image by 1 pixel
ImageEnView1.MouseWheelParams.Action := iemwVScroll;
ImageEnView1.MouseWheelParams.Variation := iemwAbsolute;
ImageEnView1.MouseWheelParams.value := 1;

Ale
