Capture last user performed action?

Report · May 29, 2019

Hello,

We are trying to capture data on how our users are cropping images. We have a script that pops up a crop box, the user adjusts that crop box, hits enter, and it crops. We would like to capture the TOP, BOTTOM, LEFT, RIGHT, and ANGLE that the user adjusted the crop box to before hitting enter. I know that in ScriptListener it outputs these variables, but is there a way to capture these inside of the current script we are running? Here is the script we are running:

var docRef = app.activeDocument;

var r = docRef.width / 560;

var left = 0;

var right = docRef.width;

var top = (docRef.height - (336 * r)) / 2;

var bottom = (docRef.width + (336 * r)) / 2;

// ======================================================= CROP

var idCrop = charIDToTypeID( "Crop" );

var desc146 = new ActionDescriptor();

var idT = charIDToTypeID( "T " );

var desc147 = new ActionDescriptor();

var idTop = charIDToTypeID( "Top " );

var idPxl = charIDToTypeID( "#Pxl" );

desc147.putUnitDouble( idTop, idPxl, top );

var idLeft = charIDToTypeID( "Left" );

var idPxl = charIDToTypeID( "#Pxl" );

desc147.putUnitDouble( idLeft, idPxl, left);

var idBtom = charIDToTypeID( "Btom" );

var idPxl = charIDToTypeID( "#Pxl" );

desc147.putUnitDouble( idBtom, idPxl, bottom );

var idRght = charIDToTypeID( "Rght" );

var idPxl = charIDToTypeID( "#Pxl" );

desc147.putUnitDouble( idRght, idPxl, right );

var idRctn = charIDToTypeID( "Rctn" );

desc146.putObject( idT, idRctn, desc147 );

var idAngl = charIDToTypeID( "Angl" );

var idAng = charIDToTypeID( "#Ang" );

desc146.putUnitDouble( idAngl, idAng, 0.000000 );

var idDlt = charIDToTypeID( "Dlt " );

desc146.putBoolean( idDlt, true );

var idcropAspectRatioModeKey = stringIDToTypeID( "cropAspectRatioModeKey" );

var idcropAspectRatioModeClass = stringIDToTypeID( "cropAspectRatioModeClass" );

var idtargetSize = stringIDToTypeID( "targetSize" );

desc146.putEnumerated( idcropAspectRatioModeKey, idcropAspectRatioModeClass, idtargetSize );

var idWdth = charIDToTypeID( "Wdth" );

var idPxl = charIDToTypeID( "#Pxl" );

desc146.putUnitDouble( idWdth, idPxl, 560.000000 );

var idHght = charIDToTypeID( "Hght" );

var idPxl = charIDToTypeID( "#Pxl" );

desc146.putUnitDouble( idHght, idPxl, 336.000000 );

var idRslt = charIDToTypeID( "Rslt" );

var idRsl = charIDToTypeID( "#Rsl" );

desc146.putUnitDouble( idRslt, idRsl, 300.000000 );

executeAction( idCrop, desc146, DialogModes.ALL );

// let user adjust crop box

// capture top, bottom, left, right, and angle that the user adjusted the crop box to

return cropBoxArguments

A way to do what you want to do is instead of putting the user into an interactive crop is to set an rectangle selection perhaps a select all then put the user into an interactive transform selection to have them select the crop they want. When they commit the transform the script can capture the selection top left and bottom right bounds then do an Image Crop.

If you want the user to be able to do ad crop and straighten do that in two steps, First have the straighten the omage. Capture the angle of Rotation used then to the transform.

If you want to to is in as single Process perhaps you could set a rectangle Path the canvas size and put the user into an interactive transform path. When the user commits the transform. You cans get the four control points and figure the angle rotation. Rotate the image and then crop the the path's selection. The Problem there is the user could easily distort the rectangle path the crop would still be rectangular. However, the crops content would not be only be the image content that was insude the transform Path.

The Problem I see with using your interactive Crop method is before the interactive crop you can get the canvas size and after the interactive crop you can get the canvas size. However how would you know if there was any straightening rotation or what part of the original Image is the crop area. With the transform selection method you can get the bounds of the selection to know what part of the image is the crop area.

The problem with any Interactive Transform is the user can easily change the shape of the rectangular path or selection to a none rectangular shape.

Perhaps if you change the users preferences to record history you could get some information from the history log about the crop that was performed. I do not think you can get at data in the History palette states. I have never logged history so I do not know what is recorded in History log metadata.

This will return the bounds, but the angle is not in the descriptor.

var docRef = app.activeDocument;
var r = docRef.width / 560;
var left = 0;
var right = docRef.width;
var top = (docRef.height - (336 * r)) / 2;
var bottom = (docRef.width + (336 * r)) / 2;
// ======================================================= CROP
alert(Crop(left,top,right,bottom));
function Crop(left,top,right,bottom) {
var ad = new ActionDescriptor();
var ad2 = new ActionDescriptor();
ad2.putUnitDouble( charIDToTypeID( "Top " ), charIDToTypeID( "#Pxl" ), top );
ad2.putUnitDouble( charIDToTypeID( "Left" ), charIDToTypeID( "#Pxl" ), left);
ad2.putUnitDouble( charIDToTypeID( "Btom" ), charIDToTypeID( "#Pxl" ), bottom );
ad2.putUnitDouble( charIDToTypeID( "Rght" ), charIDToTypeID( "#Pxl" ), right );
ad.putObject( charIDToTypeID( "T   " ), charIDToTypeID( "Rctn" ), ad2 );
ad.putUnitDouble( charIDToTypeID( "Angl" ), charIDToTypeID( "#Ang" ), 0.000000 );
ad.putBoolean( charIDToTypeID( "Dlt " ), true );
ad.putEnumerated( stringIDToTypeID( "cropAspectRatioModeKey" ), stringIDToTypeID( "cropAspectRatioModeClass" ), stringIDToTypeID( "targetSize" ));
ad.putUnitDouble( charIDToTypeID( "Wdth" ), charIDToTypeID( "#Pxl" ), 560.000000 );
ad.putUnitDouble( charIDToTypeID( "Hght" ), charIDToTypeID( "#Pxl" ), 336.000000 );
ad.putUnitDouble( charIDToTypeID( "Rslt" ), charIDToTypeID( "#Rsl" ), 300.000000 );
var desc = executeAction( charIDToTypeID( "Crop" ), ad, DialogModes.ALL );
var desc2 = desc.getObjectValue(stringIDToTypeID("to"))
var l=desc2.getDouble (charIDToTypeID( "Left" ) ).toFixed(0);
var t=desc2.getDouble (charIDToTypeID( "Top " ) ).toFixed(0);
var r=desc2.getDouble (charIDToTypeID( "Rght" ) ).toFixed(0);
var b=desc2.getDouble (charIDToTypeID( "Btom" ) ).toFixed(0);
return [l,t,r,b];
};

Is there documentation somewhere on what values are available to extract from executeAction?

How did you know "Left", "Top ", "Rght", and "Btom" were available? Is there a way to see everything without extracting each one at a time?

Here is an example of seeing what is there...

var docRef = app.activeDocument;
var r = docRef.width / 560;
var left = 0;
var right = docRef.width;
var top = (docRef.height - (336 * r)) / 2;
var bottom = (docRef.width + (336 * r)) / 2;
// ======================================================= CROP
alert(Crop(left,top,right,bottom));
function Crop(left,top,right,bottom) {
var ad = new ActionDescriptor();
var ad2 = new ActionDescriptor();
ad2.putUnitDouble( charIDToTypeID( "Top " ), charIDToTypeID( "#Pxl" ), top );
ad2.putUnitDouble( charIDToTypeID( "Left" ), charIDToTypeID( "#Pxl" ), left);
ad2.putUnitDouble( charIDToTypeID( "Btom" ), charIDToTypeID( "#Pxl" ), bottom );
ad2.putUnitDouble( charIDToTypeID( "Rght" ), charIDToTypeID( "#Pxl" ), right );
ad.putObject( charIDToTypeID( "T   " ), charIDToTypeID( "Rctn" ), ad2 );
ad.putUnitDouble( charIDToTypeID( "Angl" ), charIDToTypeID( "#Ang" ), 0.000000 );

var desc = executeAction( charIDToTypeID( "Crop" ), ad, DialogModes.ALL );
var desc2 = desc.getObjectValue(stringIDToTypeID("to"))
var l=desc2.getDouble (charIDToTypeID( "Left" ) ).toFixed(0);
var t=desc2.getDouble (charIDToTypeID( "Top " ) ).toFixed(0);
var r=desc2.getDouble (charIDToTypeID( "Rght" ) ).toFixed(0);
var b=desc2.getDouble (charIDToTypeID( "Btom" ) ).toFixed(0);
actionDescriptor(desc);
actionDescriptor(desc2);
return [l,t,r,b];
};
function actionDescriptor(desc){
if(desc.typename == 'ActionDescriptor'){
    var c = desc.count;
    for(var i=0;i<c;i++){ //enumerate descriptor's keys

    }

          var res = typeIDToStringID( id );
          if(res == '' ){
               var res = typeIDToCharID( id );
          }
     }catch(e){}
     return res;
}
function zTID( s ){
     if( s.length == 4 ) var res = charIDToTypeID( s );
     if( s.length > 4 ) var res = stringIDToTypeID( s );
     return res;
}

     var z = Math.pow(10,Number(pad))
     return num <= z ? ((Number( num) + z).toString().substr(1)): num

Your code has been edited. Next time use </> for scripts, to avoid shrinked 'spaces': "T "

I meant to use code blocks while posting scripts.

Just make a crop, then copy the result from log of ScriptListener and change ALL to NO.

In Response To Nir Photo Art · Nov 13, 2021

I just did what I said and it works. Additionally by deafult it writes NO to SL, so for me is OK.
