Option to preview before and after effect on image
Hi friends!
I'm working on a script that contains a small dialog box with some buttons to apply some image effects.
It works like this:
When I open the dialog window, add a snapshot1, then I apply some color effects and levels in the image, ...... when I disable the checkbox, it returns to snapshot1 (Function Before) however, my problem is that I have no idea how to add the "After" function every time I enable the chebox, so that the image returns to the last applied effect. Every suggestion is valid. Thank you.
Script:
takeSnapshot(); /// Before
////////////////////
var dlg = new Window("dialog", "Test", {x:0, y:0, width:210, height:250} ,{closeButton: true});
levels = dlg.add('button',{x:50, y:40, width:120,height:25}, 'Levels');
color = dlg.add('button',{x:50, y:70, width:120,height:25}, 'Color balance');
Curves = dlg.add('button',{x:50, y:100, width:120,height:25}, ' Desaturate');
levels.onClick = function() {
levelss ()
app.refresh()
}
color.onClick = function() {
Colorbalance();
app.refresh()
}
Curves.onClick = function() {
Desaturate();
app.refresh()
}
/////// CHECK VIEW REUSE FILE
var check = dlg.add("checkbox", {x:50, y:130, width:93,height:25}, "View: Before / After");
check.onClick = function (){
if(this.value){
alert ("Always return to the last setting in the History palette.")
}
else{
Before () /// Before
app.refresh()
}
}
check.value= true;
Close = dlg.add('button',{x:50, y:170, width:120,height:25}, ' OK');
Close.onClick = function() {
dlg.close();
}
dlg.center();
dlg.show();
