Hi All,

I need to resize the images to thumbnail veiw the condition is width should not exceed 75 pixels and height should not exceed 50 pixels

app.preferences.rulerUnits = Units.PIXELS     

     var Wid = docRef.width;

     var Hig = docRef.height;

                if (Number(Wid) > 75)

                    {

                         docRef.resizeImage(75,null,);                 

                                           }                                   

                else if(Number(Hig) >= 50)

                    {

                        docRef.resizeImage(null,50,);

                     }

This works fine, but if the images are width 85 and hieght 200 px

The result is (75,176).  which is wrong.

Please help me to solve

regards,

Vinoth

It’s what you set it up to do by checking for height only if the width is smaller or equal 75, I guess.

You could try something like this: 

// use it at your own risk;
#target photoshop
app.preferences.rulerUnits = Units.PIXELS;
var docRef = app.activeDocument;
var theTargetDiag = 75/ 50;
var Wid = docRef.width;
var Hig = docRef.height;
var theDiag = Wid / Hig;
if (theDiag >= theTargetDiag) {
docRef.resizeImage(new UnitValue (75, "px"),null);                 
}                                   
else {
docRef.resizeImage(null, new UnitValue (50, "px"));
};

What you were doing is also what Fit image plug-in script does and scripts like the Image processor does to resize images to fit within some pixels area while maintaining the images aspect ratio. Fit an image into some pixel width and into some pixel height. In fact the images processor uses the Fit Image plugin script to do the work. Here is that code from the Image processor script

// use the fit image automation plug-in to do this work for me

function FitImage( inWidth, inHeight ) {

          if ( inWidth == undefined || inHeight == undefined ) {

                    alert( strWidthAndHeight );

                    return;

          }

          var desc = new ActionDescriptor();

          var unitPixels = charIDToTypeID( '#Pxl' );

          desc.putUnitDouble( charIDToTypeID( 'Wdth' ), unitPixels, inWidth );

          desc.putUnitDouble( charIDToTypeID( 'Hght' ), unitPixels, inHeight );

          var runtimeEventID = stringIDToTypeID( "3caa3434-cb67-11d1-bc43-0060b0a13dc4" );

          executeAction( runtimeEventID, desc, DialogModes.NO );

}
