Stack Overflow Asked on December 30, 2021
I want to label or image on a factory map. When I click on this tag, I want to open the camera in that region. My points (labels) on the factory map should be erasable, movable, clickable. It is impossible to do this with DrawImage. Instead of using graphic draw image as an alternative way, I want to create a dynamic label and affect the image of the fixed size picturebox. But I can’t assign ‘pictureBox.Image’ to the parent property for the label.
Where am I making mistakes. The picture box should be fixed and the picture in it should be zomable. But the label acts separately from the image. I request your help.
