Select Crop Tool and select a ratio (based on Filename)

I did various tests but I did not have any luck

I would like the crop to be horizontal as in the figure above

thank you

Hmm I'm struggling to get this to behave as I had hoped.

This Is how I currently do it, checking the file name of the document inform of the Brand that I am working on. I click the crop tool. I then use the drop down box in the menu bar to select the crop ratio as it happens I have them pre set to each brand ratio. After clicking it this would be then end of the script and where the user comes in to adjust the crop position etc.

I have about 10 different ratios,

IE

First 4 characters of File name>>>

AB10 = 2:3

CD10 = 3:4

EF10 = 4:5

GH10 = 5:6.

Ideally just like when you select the ratio  from the drop down box it centers itself in image.

Going to play some more. see if I can pass my script on to those that everyone has contributed. Thanks so far!

Do something like this: create a switch statement to determine what your ratios are going to be, then calculate that ratio based on the size of the image and orientation. Use the Acton manager code to crop the image. Use a 0, 0 point to start the crop in the upper left corner, then your calculations for the other dimensions, using the full width or hight of the image to set the crop. Change the AM code at the bottom to "ALL" to bring up the dialog box, so you can crop. Just be sure to reset the dialogs to "NO", or all dialogs will be popping up!

If there is no DOM scripting interface you need to look at Action Manager Scriptlistener code to script things.  Many tools can not be selected in Actions not  all things you do is Photoshop will record.   Selecting the crop tool  does not record anything when you record an action so the Scriptlistener does does not record any Action Manager script code. A way around the is selecting a tools Preset. You could create crop tool presets  for example Crop 3:4, Crop 4:3, Crop 2:3, Crop 3:2. Selecting these tool preset will both select the crop tool and also set the aspect ratio.  However there is a Problem with this also.  If your Photoshop tools preset pull-down has Current tool only checked.  You can only select those presets if the crop tool is the current tool.  If "Current Tool Only" is not checked you can select any tool's presets.  You can catch the error if you can not select the preset you know the checkbox is checked and the Crop tool is not selected.

The brush tool also records nothing.  The closest I came to scripting a tools preset is this.

// Note:  This script only works if the correct tool for the preset is currently selected.
//        Or "current tool only" is not checked in Photoshop's  "Tool Options Bar" Presets pull-down list dialog at the bottom left.  
var ToolPresetName = "JJMack soft oval red brush" ; // The Photoshop Tool preset name that you created and saved into a set   
var ToolPresetSet  = "JJMackToolsPresetsSet";       // The SetName.tpl file need to be same folder as this Photoshop script.
try {SelectToolPreset(ToolPresetName);}
catch(e) {
  if (LoadToolPresetSet(ToolPresetSet)) {
  try {SelectToolPreset(ToolPresetName);}
  catch(e) {alert('Was unable to Select the Tools Preset "' + ToolPresetName + '".\nUncheck Preset pulld-down dialog "Current Tool Only" check box');}
  }
  else {alert("Was unable to load Tools Presets Set " + ToolPresetSet);} 
}
// =================================================== Helper functions ===================================================== // 
function SelectToolPreset(PresetName) {
  // === Select Preset, tool must be selected or 'show current tool only' unchecked  ===
  var desc = new ActionDescriptor();
  var ref = new ActionReference();
  ref.putName( stringIDToTypeID( "toolPreset" ), PresetName );
  desc.putReference( charIDToTypeID( "null" ), ref );
  executeAction( charIDToTypeID( "slct" ), desc, DialogModes.NO );
}
function LoadToolPresetSet(SetName) {
  returncode = true;
  var scriptLocation = String(findScript());
  var path = scriptLocation.substr(0, scriptLocation.lastIndexOf("/") + 1 ) ;
  var SetFile = new File(path + SetName + ".tpl");   // Requited to be in the script's folder 
  if (!SetFile.exists) { returncode = false; }
  else {
  try {LoadToolsSet(SetFile);}
  catch(e) { returncode = false; }
  }
  return returncode ;
}
function LoadToolsSet(tplFile) {
  // ========load a set of Tools Presets=========================
  var desc = new ActionDescriptor();
  var ref = new ActionReference();
  ref.putProperty( charIDToTypeID( "Prpr" ), stringIDToTypeID( "toolPreset"  ));
  ref.putEnumerated( charIDToTypeID( "capp" ), charIDToTypeID( "Ordn" ), charIDToTypeID( "Trgt"  ) );
  desc.putReference( charIDToTypeID( "null" ), ref );
  desc.putPath( charIDToTypeID( "T   " ), new File( tplFile ) );
  desc.putBoolean( charIDToTypeID( "Appe" ), true );
  executeAction( charIDToTypeID( "setd" ), desc, DialogModes.NO );
}
// Find the location where this script resides
function findScript() {
  var where = "";
  try { FORCEERROR = FORCERRROR;}
  catch(err) { where = File(err.fileName);}
  return where ;
}

I think this will need the AM code for a crop with »DialogModes.ALL« and the correctly calculated proportions.
