In communication and collaboration platforms (which may support, among other things, video conferencing, online meetings, screen sharing, webinars, etc.), annotation is a critical feature. That feature is playing a very important role during the Coronavirus Disease 2019 (COVID-19) period where, for example, universities and companies are relying heavily upon online meeting experiences to seamlessly deliver classes, sessions, presentations, etc. However, current annotation capabilities are not able to adapt to the dynamic nature of a screen share. To address such a challenge, techniques are presented herein that enhance scrolling within or the resizing of an underlying application. Aspects of the presented techniques encompass the binding of a scroll position to drawn annotations, the establishment of a relationship between annotations and application size, the automatic adjustment of pixel density following the resizing of an application, and the normalizing of a pixel's density.
