I am using Uploader Suite 8.0.8 using ASP.NET MVC 4. I am using the JavaScript API to add an uploader in my view:

Code:

<script type="text/javascript" src="/Assets/Scripts/ImageUploader/aurigma.uploader.js"></script>
<script type="text/javascript">
    var u = $au.uploader({
        id: 'Uploader1',
        width: '1180px',
        height: '480px',
        licenseKey: '@ViewBag.LicenseKey',
        converters: [{ mode: '*.*=SourceFile' }],
        javaControl: {
            codeBase: '/Assets/Scripts/ImageUploader/Uploader8.jar'
        },
        activeXControl: {
            codeBase: '/Assets/Scripts/ImageUploader/Uploader8.cab',
            codeBase64: '/Assets/Scripts/ImageUploader/Uploader8_x64.cab'
        },
        metadata: {
            cookie: 'ASP.NET_SessionId=@Session.SessionID;@FormsAuthentication.FormsCookieName=@Request.Cookies[FormsAuthentication.FormsCookieName].Value'
        },
        uploadSettings: {
            actionUrl: '@Url.Action("Upload", new { id = Model.ProductId })',
            redirectUrl: '@Url.Action("Index", new { id = Model.ProductId })'
        }
    });

    u.writeHtml();
</script>

In the Upload Action of my controller, I have something like this:

Code:

[HttpPost]
public ActionResult Upload(int id, FormCollection collection)
{
    var pictureSaver = new PictureSaver();

    for (int i = 0; i < Request.Files.Count; i++)
    {
        var httpPostedFileBase = Request.Files[i];
        if (httpPostedFileBase != null && httpPostedFileBase.ContentLength > 0)
        {
            pictureSaver.Save(httpPostedFileBase);
        }
    }

    return new EmptyResult();
}

This is all working fine, except for one thing: when I rotate images in the Uploader, they are not rotated after saving them. Is this because *.*=SourceFile is never rotated and I need to use an extra converter for that, or do I need to manually inspect the Angle_X POST-parameters and rotate the images myself?

Hi Kristof,

Yes, you are correct when thinking the problem is in converter settings.

Using SourceFile converter means uploading the image (or file in general) without any modifications. Rotating the image before upload modifies the file, but the converter knows it should upload the original one.

So, to be able to upload rotated images please use the following converter:

Code:
converters: [{mode: '*.*=Thumbnail; *.*=SourceFile', thumbnailFitMode: 'ActualSize'}]

With these settings you will get the image of original size, but with rotating applied. Note I used multiple masks in mode property to make single converter work with all file types - if the converter fails to generate a thumbnail for the file (say, you upload PDF) it sends source file.

Please learn more about uploading rotated images here.

Let me know if you have any additional questions.

Best regards,

Hi Pauline,

Thanks for clearing this up. Another quick question: I believe all images that are modified client-side (rotated, cropped, resized) before uploading are converted to the JPG format, right? So if a user selects a .png or a .gif file but rotates it before uploading, those files are actually transmitted as jpg files. Is that correct?

Yes, that is correct. If uploader creates a thumbnail for the image, the results would be in JPEG.
