I checked how to implement image classification with arfoundation
and I found out https://qiita.com/cvusk/items/77d5afef76447d173f02
it also provide with github repository link but failed to run it.
so, I made my own new project then move all the files to my new project folder
but on android device, it keep show error on
detector.Invoke(cameraTexture);
error is
NullReferenceException Object reference not set to an instance of an object
it seems cameraTexture is null...
anyone success in run above example?

When I try to run my app I get the error
Unable to resolve "../assets/icon.png" from "app\assets\screens\WelcomeScreen.js"
Error: Problems validating asset fields in app.json. See https://docs.expo.io/
• Field: icon - cannot access file at './assets/icon.png'.
I created a screens folder and input my homescreen into it as I heard that the majority of the react native community does things that way. Attached is a picture of my filesenter image description here
I think that the image path is off, however I had changed it multiple times and am still getting the same error.
Any help would be appreciated.
try the following: ../icon.png
Cause that's what I can see from your file structure.
If you use visual studio code as dev tool, when you type path cue, correct path will be appeared. so you can avoid to make mistake in path of image.
I want to make a simple .exe application in vb.net. The application wont have an installation just pure run on .exe file .
Application has one form and two pictures. When i set the option on image to build action - compile
Unable to open module file 'C:\Users\t3cho\documents\visual studio 2013\Projects\Apps\Apps\Resources\power.png': System Error &H80041feb&
Is there any other way to make an .exe file with images without installation or additional folders.
The easiest way to include images (and other types of resources) into the application is to right-click the project, go to the "Resources"-Tab and add the image there. You can change its name to e.g. MyEmbeddedImage and access it like this
Dim img As Image = Properties.Resources.MyEmbeddedImage
or
Dim img As Image = My.Resources.MyEmbeddedImage
This automatically sets the Build Action to None.
Note: This approach is type-safe and you will get errors at compile time, if the image is missing.
See: My.Resources Object and How to: Add or Remove Resources
If you still want to embed the image "manually", you must set the Build Action to Embedded Resource and access it as #Icemanind describes.
Yes. It's called embedded resources. Set your image's Build Action to Embedded Resource. You can then get the image at runtime like so:
Try
_assembly = [Assembly].GetExecutingAssembly()
_imageStream = _assembly.GetManifestResourceStream("MyNameSpace.MyImage.png")
' Do something with _imageStream
Catch ex As Exception
' Resource not found or something went wrong
End Try
I've just installed mogenerator using one of tutorials. I have added run script to my new target, and clicked Cmd+B. I should get some new files, but i didn't. In my .xcdatamodeld i have 2 entities (User and Repos). Below you can find my print screen of my project.
Where is the problem in my thinking? What should i do more? Please, help me, because i haven't found the solution on the web yet.
This all looks fine (judging by your screenshot).
One thing to check - which caused me the same issue - is that, when you've created your Entities in the xcdatamodelId file, make sure that you click on the Data Model Inspector icon, and that each entity has a Name value, and a matching "Class" value.
Miss out the Class name, and nothing will get generated.
Btw, when you click on Build, do you get a "Build succeeded" message ?
Here's the tutorial I followed to get mogenerator working:
RaptureInVenice
I should say, I've used mogenerator in a few projects, and this command line bit is always the piece that gives me trouble. Sometimes, I have to select my xcdatamodelId file, and create a new Version of it, before mogenerator will use it. But once it is working, it's a blessing.
Anything to avoid having to use the needlessly over-complicated CoreData stuff.
Someone should remind Apple that it's 2014...
I'm currently following this tutorial but using MonoGame :
http://www.riemers.net/eng/Tutorials/XNA/Csharp/Series1/Terrain_from_file.php
As said in the tutorial, my main goal is to render a terrain from an image file.
There is a .fx provided with the tutorial which I included in my project.
I had some issues using MonoGame to load the bmp file for example and now I managed to load it. The problem comes now from the fx file. MonoDevelop tells this : The MGX File is Corrupt !
Here is the original code from the writer of the article :
effect = Content.Load<Effect> ("effects");
And here is how I used it with MonoGame :
effect = Content.Load<Effect> ("effects.fx");
I am really lost about the usage of the effects file in MonoGame. Is there any good tutorial about this ? Anyway I'm really lost with MonoGame. How come there is no clear tutorials for MonoGame has it is widely used ?
You need to convert your shader .fx to appropriate file format for monogame using 2MGFX tool. You can find the tool inside installed monogame directory C:\Program Files (x86)\MSBuild\MonoGame\v3.0
How to use:
Create a .bat file and write code as shown below:
2MGFX.exe effects.fx effects.mgfxo
pause
Execute the .bat file
Note that the shader file, .bat file and 2MGFX.exe must be in same directory.
Here is how to use compiled .mgfxo file as effect:
Put the effects.mgfxo into Assets\Content folder of your project
Load a file as shown below
Stream s = Assembly.GetExecutingAssembly().GetManifestResourceStream("ProjectNameSpace.Assets.Content.effects.mgfxo");
BinaryReader Reader = new BinaryReader(s);
Effect effect = new Effect(graphics, Reader.ReadBytes((int)Reader.BaseStream.Length));
If you have problems converting a shader .fx to .mgfxo please leave comments.
I've been trying to follow Riemers tutorial myself, like you, I struggled with the effects.
I had to make a couple changes to the original effects file before I successfully managed to compile and use it without any exceptions.
Renamed the following:
vs_2_0 to vs_4_0
ps_2_0 to ps_4_0
POSITION to SV_POSITION
Once these changes were made I used the compile tool like following:
2MGFX.exe effects.fx effects.mgfxo /Profile:DirectX_11
Once compiled I moved the mgfxo file into my contents folder and assigned following parameters:
Build action: Embedded resource
Copy to output directory: Copy always
It took me a couple of attempts until I managed to use the shader without MonoGame throwing any exceptions at me.
byte[] bytes = File.ReadAllBytes("Content/effects.mgfxo");
effect = new Effect(GraphicsDevice, bytes);
Using the 2MGFX tool is optional, you can either use the tool or the Content pipeline, personally I prefer the Content pipeline because it will automatically process the shader file everytime I (re)build the Content project.
How to do this?
First: add a MonoGame Content project,
Then add the .FX file in this project
Set the Content processor to: "MonoGame effect content processor" in properties
Then, in your game project Add a Reference to this Content project.
And use the shader like so:
var myEffect = Content.Load<Effect>("shaderFileNameWithoutExtension");
or if you have folders in your content project:
var myEffect = Content.Load<Effect>("FolderName\\shaderFileNameWithoutExtension");
I'm seeing you're working on Linux. Compiling shaders on Linux is a little difficult. In my own projects, I find the following resource especially helpful.
http://www.infinitespace-studios.co.uk/general/monogame-building-fx-shaders-on-a-mac-and-linux/
Following this, you're able to build shaders using the MonoGame Pipeline as normal (provided you have added the pipeline reference).
Hope this helps!
Im relatively new to programming and am just in the process of uploading my first app to the app store however i am getting the following error message which i just can't figure out / fix. I have looked everywhere online for a solution but as yet, no luck. Please can someone help? I am using Xcode 5:
Error:
ERROR ITMS-9000: "Invalid Image Path - No image found at the path referenced under key 'CFBundleIcons': 'AppIcon40x40'" at SoftwareAssets/SoftwareAsset (MZItmspSoftwareAssetPackage)
This really doesn't mean anything to me as i have tried all the usual asset catalogue stuff / looked at my p-list.
You need an App Icon.
If you created the project in Xcode 5 then there should be a catalogue called Images.xcassets where you should place the icons of the correct sizes for your app.
I have added a screenshot of my app as an example of what I am talking about:
I saw the same error. First I thought that the images where not correct (I found one with 144 dpi), but the error showed up again.
Just search for the exact name "AppIcon40x40" in the whole project using Shift+Cmd+F. I have seen it referenced in a plist file under another key. There you have to change the names to the appropriate ones.
