Control the camera zoom #2

Closed SureshbabuAkash1999 closed 3 years ago

I am building a GUI application for my camera (sonyHx400v) using this library. The problem that I face is that I am not able to control the zoom to a particular value, even though I am able to zoom in and zoom out using 1shot.

Hi,

From looking at the documentation, it doesn't seem that it is possible to zoom to a particular value.

However, a possible solution could be to combine actZoom and Event notification (getEvent) to create a feedback loop of sorts.

You could use the zoomPosition value that is returned to figure out how far you are zoomed in. Then keep calling actZoom with the 1shot movement parameter and read zoomPosition again until you reach your desired zoom percentage.

Hope that helps.
