Answer 1

Hi JJMACK,
                  I am using adobe  Flex with  Photoshop scripting . I am sending  Flex file  with parameter to generate .psd.Right now i am able to generate 72 DPI with proper image size while  I am generating  .psd with  250 DPI with Improper Size.
E.g
This is my  flex parameters
MgrPSAction.instance.FinishLayoutToPhotoshop(curFl , savedType ,TemplateConstant.TM_LEFT,getPSDImageName(objItem,TemplateConstant.TM_LEFT_RIGHT), objItem.LayoutTMLWidth,objItem.LayoutTMLHeight ,pageDPI,returnPhotoshopHandler,
true,setWidth , setHeight,formatQty); ----- Page DPI - > like 72 or 250 paasing  from here.
below is Scirpt ot resize
function openFileAndResize(xp,yp,wi,hi,imagepath)
var fileRef = new File(imagepath);
var curRefDoc = app.open(fileRef);
var curw = curRefDoc.width;
var curh = curRefDoc.height;
var resW;
var resH;
var scw = imgObj.wi/curw;
var sch = imgObj.hi/curh;
var scale ;
if(scw > sch)
scale = scw;
else
scale = sch;
resW = curw * scale;
resH = curh * scale;
if(imgObj.isAdjustImage == "true")
resW = resW * parseFloat (imgObj.scaleOrg);
resH = resH * parseFloat (imgObj.scaleOrg);
// Resize Image=======================================================
var idImgS = charIDToTypeID( "ImgS" );
var desc226 = new ActionDescriptor();
var idWdth = charIDToTypeID( "Wdth" );
var idPxl = charIDToTypeID( "#Pxl" );
desc226.putUnitDouble( idWdth, idPxl, resW);
var idHght = charIDToTypeID( "Hght" );
var idPxl = charIDToTypeID( "#Pxl" );
desc226.putUnitDouble( idHght, idPxl, resH );
var idIntr = charIDToTypeID( "Intr" );
var idIntp = charIDToTypeID( "Intp" );
var idBcbc = charIDToTypeID( "Bcbc" );
desc226.putEnumerated( idIntr, idIntp, idBcbc );
executeAction( idImgS, desc226, DialogModes.NO );
// Select Image=======================================================
var idsetd = charIDToTypeID( "setd" );

desc263.putReference( idnull, ref138 );
var idT = charIDToTypeID( "T " );
var idOrdn = charIDToTypeID( "Ordn" );
var idAl = charIDToTypeID( "Al " );
desc263.putEnumerated( idT, idOrdn, idAl );

//Copy Image=======================================================
var idcopy = charIDToTypeID( "copy" );
executeAction( idcopy, undefined, DialogModes.NO );
app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);
//Create Temp Layer for image adjustment =======================================================
//createApplication(wi,hi,dpi,"imagelayerdoc");
createApplication(wi,hi,dpi,layerAppName);
//var curDoc = getCurDoc('imagelayerdoc');
//get Active Temp Layer for image adjustment =======================================================
var curDoc = getCurDoc(layerAppName);
app.activeDocument = curDoc;
// Past Copy image in Temp Layer for image adjustment =======================================================
var idpast = charIDToTypeID( "past" );
var desc250 = new ActionDescriptor();
var idAntA = charIDToTypeID( "AntA" );
var idAnnt = charIDToTypeID( "Annt" );
var idAnno = charIDToTypeID( "Anno" );
desc250.putEnumerated( idAntA, idAnnt, idAnno );
executeAction( idpast, desc250, DialogModes.NO );
// HERE YOU NEED TO SET XY POSTION OF IMAGE
positionLayer(app.activeDocument.activeLayer,imgObj.moveX,imgObj.moveY);
cropImage();
Please reply if have answer...
Thanks
