Question

See more:

I would like to add WriteableBitmapEx lib in my Window Store Application. I just just looked with Manage NuGet packages find and found WriteableBitmapEx and installed it. No problem.

C# project.

I checked my References and there I can see WriteableBitmapEx.WinRT. Even I was able to see in my Object Browser.
Now I wanted to use it in my code but I am unable to find using WriteableBitmapEx.WinRT

VS 2012 is giving me error, unable to find it.

What I am doing wrong? Any Idea?

Your help will be very much appriciated.

Best regards

Did you add a reference to the library to your project using "Add reference"? What do you mean by "unable to find"? Where did you try to find it and how?

It will not let me add

My code look something like this

using Windows.UI.Xaml.Controls;
using System.Collections.ObjectModel;
using GameTools;
using Windows.UI.Xaml.Media.Imaging;
using System.Threading.Tasks;
using Windows.Storage.Streams;
using System.IO;
using System.Reflection;
using Windows.Storage;
using WriteableBitmapEx.WinRT;

There is RED line under using WriteableBitmapEx.WinRT;

I am unable to make any reference to that WriteableBitmapEx.
For example I want to create an image of such type I will not able to do so.
You may create a dummy project and try to add it. You will be able to see that in your reference but you will NOT able to use it.

Thank you very much for replying back.

I created a new blank store application.
Clicked on Manage NuGet packages…
Search for WriteableBitmapEx and found and pressed install button.
Installed on my app and now I see the green check button.
Successfully installed 'WriteableBitmapEx 1.0.7.0'.
Added reference 'WriteableBitmapEx.WinRT' to project 'App2'
Added file 'packages.config'.
Added file 'packages.config' to project 'App2'
Successfully added 'WriteableBitmapEx 1.0.7.0' to App2.
Looked in my references and I see in my Object Browser it is there. I can see the path as well.
Assembly WriteableBitmapEx.WinRT
C:\Apps\App2\packages\WriteableBitmapEx.1.0.7.0\lib\NetCore45\WriteableBitmapEx.WinRT.dll

Goto to MainPage.xaml.cs and try to add using WriteableBitmapEx name space which VS 2012 unable to find it.
I am not sure how I can write code when I don’t have any reference to the library.

Thank you for prompt reply.

Thank you, it's getting more clear.
"Stranger and stranger, wonderfuller and wonderfuller..." :-)
As this is so strange, going into finer detail. What does it mean, more exactly "VS 2012 unable to find it" and "...I don't have any referenced to the library"? How "not found" was manifested, exactly? How can you say "... I don't have any..." if one line above you said that you saw this reference?

Could you exactly answer my questions? I'm not asking about the code yet. You did not answer if you tried to add the reference to the project, how you tried it (if you tried at all), and what happened, exactly.

My MainPage.xaml.cs start looks like this
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using Windows.Foundation;
using Windows.Foundation.Collections;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Controls.Primitives;
using Windows.UI.Xaml.Data;
using Windows.UI.Xaml.Input;
using Windows.UI.Xaml.Media;
using Windows.UI.Xaml.Navigation;
Next I would like to add Using “using WriteableBitmapEx.WinRT;”
I am using Microsoft visual studio 12. When you start typing Microsoft visual studio 12 will pop up a list where you could find appropriate list of word, but I could not find it and wrote it in anyway. When I compile I get the message
Error 1 The type or namespace name 'WriteableBitmapEx' could not be found (are you missing a using directive or an assembly reference?) C:\Apps\ImageTest\ImageTest\MainPage.xaml.cs 14 7 ImageTest
Because I have written (To test it) there or four application you can produce on your machine. I don't think you have any problem what so ever not to reproduce it.
Thank you prompt reply
Best regards

Could you write fully-qualified name of WriteableBitmapEx. Are you sure the namespace name is WriteableBitmapEx.WinRT? If so, the type must be WriteableBitmapEx.WinRT.WriteableBitmapEx... looks strange... will you check up this part? Forget "using", it only obscure the problem...

I have sent you cut/paste from my application. I just looked in my Object Browser and copy this path. Assembly WriteableBitmapEx.WinRT
C:\Apps\App2\packages\WriteableBitmapEx.1.0.7.0\lib\NetCore45\WriteableBitmapEx.WinRT.dll

This text is from my output window.
Added file 'WriteableBitmapEx.1.0.7.0.nupkg' to folder 'WriteableBitmapEx.1.0.7.0'.
Successfully installed 'WriteableBitmapEx 1.0.7.0'.
Added reference 'WriteableBitmapEx.WinRT' to project 'App2'
Added file 'packages.config'.
Added file 'packages.config' to project 'App2'
Successfully added 'WriteableBitmapEx 1.0.7.0' to App2.

I don't have any missunderstanding that my namespace is WriteableBitmapEx.WinRT. But I tried all combinations like WriteableBitmapEx wb = new WriteableBitmapEx() and
WriteableBitmapEx.WinRT wbr = new WriteableBitmapEx.WinRT(), but with no luck.
When I send you that is all cut/paste Not my code. Only the above line is my code.
Have you tried to add this lib any of your test application?
Thank you very much for prompt reply.

Best regards

Is if from http://writeablebitmapex.codeplex.com/?
As I can see from source code, the name project structure and space structure is kind of complicated, due to multiplatform nature of this component. Maybe you did not get it. I would advise to build it all from source. Have you been able to build code samples?
—SA

AghaKhan 18-Mar-13 2:38am

I tried to build it from source code. It has same problem. There are 3 samples and I tried to run all 3 of them one at a time. Unfortunately none of them worked.

Sergey Alexandrovich Kryukov 18-Mar-13 10:04am

That's worse. Something's wrong here. I tried to look at this solution. I could not build it because I have something not installed, and even the attempt to load all projects has failed. At least it needs isolation of unused projects, to see how it works.

AghaKhan 18-Mar-13 2:55am

Update. Now I included WriteablebitmapEx.WinRT project in my solution. Even then I am unable to use it. It has the same problem I can see inside my object browser but I will not able to use it. Very strange

AghaKhan 18-Mar-13 13:54pm

Update: Reply from CodePlex.
This is not an issue with the lib. See the samples you can download here in the Source Code repository how to include the lib in your project correctly. Also note that most WBX code is in the Windows.UI.Xaml.Media.Imaging namepsace.

I have to check again. How to add the lib!

Sergey Alexandrovich Kryukov 18-Mar-13 14:00pm

OK, your feedback would be nice.

AghaKhan 25-Mar-13 20:57pm

Dear Sergey Alexandrovich Kryukov:
unable to find any sample where it shows how to use this lib. Do you have idea?
Best regards

AghaKhan 25-Mar-13 21:22pm

I got it.
WriteableBitmapEx is extension to WriteableBitmap. So just use as WriteableBitmap image.
It works fine.
void MainPage_Loaded(object sender, RoutedEventArgs e)
{
WriteableBitmap writeableBmp = new WriteableBitmap(512, 512);
writeableBmp.Clear(Colors.White);
writeableBmp.DrawLine(1, 2, 30, 40, Colors.Green);
ImageName.Source = writeableBmp;
}

Sergey Alexandrovich Kryukov 25-Mar-13 21:26pm

I know, but it wasn't really a problem, you could not compile it. But I understand the idea: this is a set of different types under the same name. Perhaps when and if I have to address to this library, I'll see it. Anyway, congratulations, thank you for the feedback.

WriteableBitmapEx is extension to WriteableBitmap. So just use as WriteableBitmap image.
It works fine

void MainPage_Loaded(object sender, RoutedEventArgs e)
{
WriteableBitmap writeableBmp = new WriteableBitmap(512, 512);
writeableBmp.Clear(Colors.White);
writeableBmp.DrawLine(1, 2, 30, 40, Colors.Green);
ImageName.Source = writeableBmp;
}
ImageName is an image inside xaml file.

That is all.
