touchgfx::HAL::setFingerSize() method
@fn void HAL::setFingerSize(uint8_t size) Sets the finger size Sets the finger size in pixels. Setting the finger size to a size of more than 1 pixel will emulate a finger of width and height of 2*(fingersize-1)+1. This can be especially useful when trying to interact with small elements on a high ppi display. The finger size will influence which element is chosen as the point of interaction, when clicking, dragging, ... the display. A number of samples will be drawn from within the finger area and a best matching drawable will be chosen. The best matching algorithm will consider the size of the drawable and the distance from the touch point.
