Select Area Delphi

[JackieTebb]

I'm evaluating GdViewer. Is it possible to select an area and store co-ordinates and how can these be adjusted to allow for zooming?

Hi,

- To select an area:

Set the MouseMode property to 1 (MouseModeAreaSelection)

- To get the co-ordinates of the selected area:

https://www.gdpicture.com/references/gdv ... Width.html
https://www.gdpicture.com/references/gdv ... eight.html
https://www.gdpicture.com/references/gdv ... RectX.html
https://www.gdpicture.com/references/gdv ... RectY.html


- To Zomm into the area:

ZoomRect method: https://www.gdpicture.com/references/gdv ... mRect.html
