    Image Cropper - Getting Original URL

    Hello,

    I'd like to get the original source URL for an Image that's stored in Umbraco.

    The problem is when I use

     return this.GetCropUrl(imageCropMode: ImageCropMode.Max);

    The image is returned with "?mode=max&rnd=130741876440000000" which means ImageProcessing kicks in and the quality of the outputted image is then effected (colour depth reduced).

    I'd like to just return "file.gif".

    So you can get a better understanding of what's going on, here it all is:

    public string GetSquareCrop()
    {
        // Crop Disabled
        if (this.DisableCrop) return this.Url; // call this.GetCropUrl 

        // Disable ImageProcessing on GIF's
        if (this.UmbracoExtension == "gif")
        {
            // this needs replacing, to just return the image url
            return this.GetCropUrl(imageCropMode: ImageCropMode.Max);
        }

        if (this.UmbracoFile != null) return this.GetResponsiveCropUrl("Square");
        return null;
    }

    Many thanks! Laurence

    So, if I return UmbracoFile, this returns the JSON.

    So I am now taking that JSON and making it real ;-)

        public string UmbracoFile
    {
        get
        {
            var prop = this.GetPropertyValue<string>("umbracoFile");
            if (IsJson(prop))
            { 
               dynamic d = JsonConvert.DeserializeObject(prop);
               return d.src;
            }
            return prop;
        }
    }

    I assume this method is actually somewhat unrequited, and I should be able to cast the property into something that does this for me? Rather than this Dynamic wizardry! ;-)

    Hi Laurence,

    Depending on the ImageProcessor version (v2.3.0+) you might well still get the HttpModule intercepting even if you only use the original src url if you have RAMMFAR enabled in your web.config.

    Add ipignore=true to your querystring parameters and ImageProcessor will ignore the request.

    I'd love to see the input and output images if I could to see what color loss occurs.

    Cheers

    James

    The two URLs below, give a really good example of the quality lose, which I assume is a change in colour depth.

    Processed: 4.gif?mode=max
    Unprocessed: 4.gif

    It looks like that's caused by the quantizer used by Gifsicle in the PostProcessor. If you download the configuration project you can disable it.
