I am creating a web application and I am using groupdocs for view pdf and other docs,
in one of the scenario I want to change particular page orientation of pdf document, I found groupdocs merger with a set of code from here and I modified that code with my expectations which is below,
string filePath = #"c:\sample.pdf";
OrientationOptions orientationOptions = new OrientationOptions(OrientationMode.Landscape, new int[] { 3, 4 });
using (Merger merger = new Merger(filePath))
{
merger.ChangeOrientation(orientationOptions);
merger.Save(filePath);
}
but I am getting the below error
Requested ChangeOrientation operation for ‘Pdf’ document type is not
supported
I tried this in groupdocs 21.8 version
I found groupdocs merger with a set of code from here
We cannot reproduce this issue using GroupDocs.Viewer for .NET rotate pages. Have a look at the blow screenshot and the code:
using (Viewer viewer = new Viewer(#"D:/test.pdf"))
{
PdfViewOptions viewOptions = new PdfViewOptions(#"D:/output.pdf");
viewOptions.RotatePage(1, Rotation.On90Degree);
viewer.View(viewOptions);
}
As you are using GroupDocs Viewer API to render/view documents. Please use the above mentioned code. However, this issue exists in GroupDocs.Merger for .NET and we are working on the fix.

I am trying to make an asp.net mvc 5 app by this ASP.NET image upload guide.
I am curious about this part of the guide (on the photo here):
as I understand at that part I am supposed to write the code in my View (cshtml) page. (Cause before there was attaching js's and running scripts in "<"script">" tag)
How can I write such C# code in the View? Where am I wrong?
string cors_location = (new UriBuilder(Request.Url.AbsoluteUri) { Path = Url.Content("~/Content/cloudinary_cors.html") }).ToString();
C# code in a view generally belongs in a server side block like this ...
#{
string cors_location = (new UriBuilder(Request.Url.AbsoluteUri)
{ Path = Url.Content("~/Content/cloudinary_cors.html") }).ToString();
}
How can I write such C# code in the View? Where am I wrong?
Hi.
like this by adding the '#'sign
#{string cors_location = (new UriBuilder(Request.Url.AbsoluteUri) { Path = Url.Content("~/Content/cloudinary_cors.html") }).ToString();}
also please check http://www.asp.net/web-pages/overview/getting-started/introducing-razor-syntax-c
my server should get a link of uploaded file
To manage this You should do something like this:
create property in Your model class for eg.
public string ImgUrl {get;set;}
In Your View controller you should pass url value from view
Img.Url = "My Image Url passed from View";
and then save Your model to Db.

I try to get the service metadata of a sapui5 v2 odata model.
Code:
var oModel = new sap.ui.model.odata.v2.ODataModel(someServiceURL);
var oMetadata = oModel.getServiceMetadata();
This should work according to this page:
https://openui5beta.hana.ondemand.com/docs/guide/6c47b2b39db9404582994070ec3d57a2.html
Anyhow I got "undefined" for oMetadata.
If I change code to:
var oModel = new sap.ui.model.odata.v2.ODataModel({
loadMetadataAsync : false,
serviceUrl : someServiceURL
});
Still oMetadata === undefined
According to SDK documentation metadata should be loaded in sync:
Return the metadata object. Please note that when using the model with
bLoadMetadataAsync = true then this function might return undefined
because the metadata has not been loaded yet. In this case attach to
the metadataLoaded event to get notified when the metadata is
available and then call this function.
What is wrong with my code?
I am using (1.28.11):
<script src="https://sapui5.netweaver.ondemand.com/resources/sap-ui-core.js" ...
I started debugging the UI5 code and detected following line:
this.bLoadMetadataAsync = true;
I started debugging of SAPUI5 code and detected following line (seems to be called each time):
this.bLoadMetadataAsync = true;
Is it a bug? Or is something wrong with my code?
Solution:
The following worked for me in an actual application environment. I guess it not being fired in my fiddle was due to no actual data request being made:
var oModel = new sap.ui.model.odata.v2.ODataModel(<ServiceURL>);
oModel.attachMetadataLoaded(null, function(){
var oMetadata = oModel.getServiceMetadata();
console.log(oMetadata);
},null);
Lead up to the solution:
Ok so I started playing around with this a bit and found the following:
.getServiceMetadata() worked fine with sap.ui.model.odata.ODataModel.
with the sap.ui.model.odata.v2.ODataModel the request for the metadata was sent through the network but somehow .getServiceMetadata() returned undefined.
I tried to sap.ui.model.odata.v2.ODataModel.attachMetadataLoaded() but the event was never fired. (This only applied in the jsbin I used)
I will edit this with any further findings I make. If you have anything that should be included in my findings/testing just tell me.
Edit:
The bLoadMetadataAsync is a parameter you can set on the sap.ui.model.odata.ODataModel. The parameter is not in the API for sap.ui.model.odata.v2.ODataModel anymore. I assume that the async loading has been choosen as default.
Edit:
#user3783327 Reported a bug here: https://github.com/SAP/openui5/issues/564
As sirion already mentioned, the ODataModel has now an API named metadataLoaded which returns a promise accordingly. In the resolve function, we can definitely get the service metadata via getServiceMetadata().
myODataModel.metadataLoaded()
.then(() =>/* Do something with */myODataModel.getServiceMetadata());
Alternatively, we can also make use of ODataMetaModel which can be set on any ManagedObject (including View) and provides several useful accessors related to the service metadata. In order to get the meta model, we need to use the appropriate API from the ODataModel instead of instantiating the model directly:
myODataModel.getMetaModel().loaded()
.then(() =>/* Do something with */myODataModel.getMetaModel()/*...*/);

in a mobile application i need to send an image which the user either took with the camera or picked from a cameraroll.
I am using the starling framework and feathersUI ( although i think this does not matter to problem )
When the mediapromise is loaded using loadFilePromise i use the following code to deal with the image data:
_mediaLoader = new Loader()
//loading the filePromise from CameraRoll
_mediaLoader.loadFilePromise(_mediaPromise);
_mediaLoader.contentLoaderInfo.addEventListener(starling.events.Event.COMPLETE, onLoadImageComplete);
private function onLoadImageComplete(event:flash.events.Event=null):void {
//creating the starling texture to display the image inside the application
var texture:Texture = Texture.fromBitmapData(Bitmap(_mediaLoader.content).bitmapData, false, false, 1);
//now trying to load the content into a bytearray to send to the server later
var bytes:ByteArray=_mediaLoader.contentLoaderInfo.bytes;
}
the last line of code results in a Security error:
Error #2044: Unhandled SecurityErrorEvent:. text=Error #2121: Security sandbox violation: app:/myapp.swf: http://adobe.com/apollo/[[DYNAMIC]]/1 cannot access . This may be worked around by calling Security.allowDomain.
I tried
Security.allowDomain("*")
as a test
but then i get:
SecurityError: Error #3207: Application-sandbox content cannot access this feature.
As a workaround i write my own png ByteArray inside the Application from the loaders BitmapData using Adobes PNGEncoder Class:
var ba:ByteArray=PNGEncoder.encode(Bitmap(_mediaLoader.content).bitmapData)
But this takes a significant amount of time ...
I also tried the FileReference to load the image but
_mediaPromise.file
and
_mediaPromise.relativePath
are both null.
What am I doing wrong? Or is this a known problem ?
Thanks!
Hello I have found a solution based on a post about the processing of exif data mentioned here: http://blogs.adobe.com/cantrell/archives/2011/10/parsing-exif-data-from-images-on-mobile-devices.html
the crucial code
private function handleMedia(event:MediaEvent):void{
_mediaPromise=event.data as MediaPromise;
_imageBytes=new ByteArray()
var mediaDispatcher:IEventDispatcher = _mediaPromise.open() as IEventDispatcher;
mediaDispatcher.addEventListener(ProgressEvent.PROGRESS, onMediaPromiseProgress);
mediaDispatcher.addEventListener(flash.events.Event.COMPLETE, onMediaPromiseComplete);
};
private function onMediaPromiseProgress(e:ProgressEvent):void{
var input:IDataInput = e.target as IDataInput;
input.readBytes(_imageBytes, _imageBytes.length, input.bytesAvailable);
};
private function onMediaPromiseComplete(e:flash.events.Event):void{
_mediaLoader = new Loader();
_mediaLoader.loadBytes(_imageBytes)
};
works like a charm for me on ipad and iphone.
We are trying to send an image as a stream to a method in Grails 2.4.3.
def imgStream
imgStream = servletContext.classLoader.getResourceAsStream("/assets/Logo.jpg")
We call in another service to render the PDF
ByteArrayOutputStream output = licensePlanReportsService.renderLicensingPlanPDF(licensingPlanInstance, internal, imgStream)
We are using com.lowagie.text.Image from iText 2.1.7 and poi 3.9-20121203
if(imgStream) {
Image logo = Image.getInstance(imgStream.getBytes())
logo.scaleAbsolute(128.64, 88.32)
logo.setAbsolutePosition(25, 485)
document.add(logo)
}
The image is not rendering for us on our output the PDF report. Does this seem to be the correct way to render the image to the PDF?
This issue was resolved by changing the initial call by using the following code:
imgStream = grailsAttributes.getApplicationContext().getResource("Logo.jpg").getInputStream()
Instead of the initial way
imgStream = servletContext.classLoader.getResourceAsStream("/assets/Logo.jpg")
Thanks,
Tom
I am developing a mobile application using phonegap, Initially I have developed using WEBSQL but now I m planning to move it on INDEXDB. The problem is it does not have direct support on IOS , so on doing much R&D I came to know using IndexedDB Polyfil we can implement it on IOS too
http://blog.nparashuram.com/2012/10/indexeddb-example-on-cordova-phonegap.html
http://nparashuram.com/IndexedDBShim/
Can some please help me how to implement this as there are not enough documentation for this and I cannot figure out a any other solution / api except this
I have tested this on safari 5.1.7
Below is my code and Error Image
var request1 = indexedDB.open(dbName, 5);
request1.onsuccess = function (evt) {
db = request1.result;
var transaction = db.transaction(["AcceptedOrders"], "readwrite");
var objectStore = transaction.objectStore("AcceptedOrders");
for (var i in data) {
var request = objectStore.add(data[i]);
request.onsuccess = function (event) {
// alert("am again inserted")
// event.target.result == customerData[i].ssn;
};
}
};
request1.onerror = function (evt) {
alert("IndexedDB error: " + evt.target.errorCode);
};

One blind guess
Maybe your dbName contains illegal characters for WebSQL database names. The polyfill doesn't translate your database names in any kind. So if you create a database called my-test, it would try to create a WebSQL database with the name my-test. This name is acceptable for an IndexedDB database, but in WebSQL you'll get in trouble because of the - character. So your database name has to match both, the IndexedDB and the WebSQL name conventions.
... otherwise use the debugger
You could set a break point onto your alert(...); line and use the debugger to look inside the evt object. This way you may get either more information about the error itself or more information to share with us.
To do so, enable the development menu in the Safari advanced settings, hit F10 and go to Developer > Start debugging JavaScript (something like that, my Safari is in a different language). Now open then "Scripts" tab in the developer window, select your script and set the break point by clicking on the line number. Reload the page and it should stop right in your error callback, where you can inspect the evt object.
If this doesn't help, you could get the non-minified version of the polyfill and try set some breakpoints around their open function to find the origin of this error.
You could try my open source library https://bitbucket.org/ytkyaw/ydn-db/wiki/Home. It works on iOS and Android.
