Zoom slider Flat panorama

jeromebg

Hi,
To update a zoom indicator for regular panoramas we can use this action :

Code

<action name="updateslider">
  sub(val, view.fov, view.fovmin);
  sub(fovrange, view.fovmax, view.fovmin);
  div(val, fovrange);
  mul(plugin[slider_grip].y, val, plugin[slider_bg].pixelheight);
</action>

but when the pano is flat how to set the correct fovmax value as it changes according to the screen and image ratio when limitview is set to auto ?
thnx !

Hi jeromebg

In this example I have code bolow:

Code

calc(val,1 - (view.fov - view.fovmin) / (view.fovmax - view.fovmin));
mul(plugin[slider_grip].x, val, plugin[slider_bg].pixelwidth);

Maybe this will help

<action name="updateslider">
calc(plugin[slider_bg].height, view.fovmax);

sub(val, view.fov, view.fovmin);
sub(fovrange, view.fovmax, view.fovmin);
div(val, fovrange);

calc(plugin[slider_grip].y, val * plugin[slider_bg].pixelheight - plugin[slider_grip].pixelheight );

if(plugin[slider_grip].y LT 0,
set(plugin[slider_grip].y,0);
);

trace(plugin[slider_grip].y);
</action>

Thanx panoyun, but what is the difference with the initial code in my initial post ?

Ok, in fact the trick was to set the fovmax according to the screen and image ratio...

Code

<events name="sliderevents" onviewchanged="updateslider();" onresize="set_fovmax()"/>


	<action name="set_fovmax">
		div(imageratio, image.hfov, image.vfov);
		div(screenratio, stagewidth, stageheight);
		if(imageratio LT screenratio,
			set(view.fovtype, HFOV);
			copy(view.fovmax, image.hfov);
		,
      		        set(view.fovtype, VFOV);
			copy(view.fovmax, image.vfov);
		);
	</action>


<action name="updateslider">
  sub(val, view.fov, view.fovmin);
  sub(fovrange, view.fovmax, view.fovmin);
  div(val, fovrange);
  mul(plugin[slider_grip].y, val, plugin[slider_bg].pixelheight);
</action>
