Hi,

Clicking on the "Apply Crop" button crops the image and then refreshes the imagePanel with the new crop image. Would it be possible to change this behavior? Ideally we would like to save the cropped image to the directory when the user clicks on "Apply Crop" and redirect them to a new page and show them the cropped image. Currently users have to click on Apply Crop and then Click on Save Changes. Would it be possible for us to change this? Please advise

Hi,

You just need to implement the following correction:

In Default.aspx you should correct Form1:
Code:
<form id="form1" runat="server">
        <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true"/>
        <div>
            <!-- Add the custom control -->
            <aur:MyControl runat="server" ID="myControl1" />
        </div>
    </form>



In PhotoEditor\Scripts\Effects\CropEffect.js correct this function:
Code:
_onApplyButtonClick: function(evt) {
		/// <private />
		var controller = $find(this._controllerId);
		var rr = $find(controller.get_rectangleRubberbandId());
		var bv = $find(controller.get_bitmapViewerId());
		if ((this._selectedSize != -1) && (rr) && (bv)) {
			// Get rectangle.
			var rect = rr.get_rectangle();

			// Set new crop rectangle.
			this._cropRect = this._transformedToOriginal(new Array(rect.x, rect.y, rect.width, rect.height));

			this._oldRect = new Array(rect.x, rect.y, rect.width, rect.height);
			//this._update();
			PageMethods.ApplyCropEffect(Sys.Serialization.JavaScriptSerializer.serialize({FileName: bv._bitmap$fileName, 
                    X: this._cropRect[0], Y: this._cropRect[1],
                    Width: this._cropRect[2], Height: this._cropRect[3] }), 
                function(result, userContext, methodName) { document.location = result; });


		}
		return false;
	},


In PhotoEditorSample\Default.aspx.cs you shoul add the following class and references:
Code:

using Aurigma.GraphicsMill.AjaxControls;
using Aurigma.GraphicsMill;
using System.Web.Script.Serialization;

PhotoEditorDefault
  private struct CropParams
    {
        public string FileName;
        public float X;
        public float Y;
        public float Width;
        public float Height;
    }

    [System.Web.Services.WebMethod]
    public static string ApplyCropEffect(string context)
    {
        JavaScriptSerializer jss = new JavaScriptSerializer();
        CropParams crop = jss.Deserialize<CropParams>(context);
        string _bitmapFileName = crop.FileName;
        Bitmap _bitmap = new Bitmap();
        FileCache fc = FileCache.GetInstance();
        using (System.IO.FileStream stream =
                               new System.IO.FileStream(fc.GetAbsolutePrivateCachePath(_bitmapFileName), System.IO.FileMode.Open, System.IO.FileAccess.Read))
        {
            _bitmap.Deserialize(stream);
        }
        _bitmap.Transforms.Crop(crop.X, crop.Y, crop.Width, crop.Height);
        string fileName = fc.GetPublicTempFileName(".jpg");
        _bitmap.Save(fc.GetAbsolutePublicCachePath(fileName));
        return fc.GetRelativePublicCachePath(fileName);
    }

Hi Tamila,

I made these changes. However I get a Javascript error when I click on the "Apply Crop Button".

'PageMethods' is undefined.

Please advise

Thanks
Sri
