What happens internally when Hardware Accelaration is on then all the screenshots taken during that time come out to be totally black.
I dont have any clue about that and have done some research but could not find anything.
I am trying to create an app 'X' in windows which will produce black screen as output when someone tries to take a screenshot while 'X' is on.
There are some apps which provide this functionality(like ScreenWings) but i could not figure out its working.
Is there any way hardware accelaration is related to this, if yes then how and if not then what can I use.
please help!!!
EDIT-- I want to do something so that screenshot comes out to be black..

I've found several tutorials on how to set up a video-streaming server, how to get information, for example the temperature and humidity, via telegram or how to save a face so it gets recognized with Esp32-Cam. But I've found nowhere on the whole internet an example for my problem. I want the Esp32-Cam to light an LED when it recognizes a face. That should be possible, shouldn't it? There are a lot of pins which can be used as output. Does someone have a idea how to do that? When I have the light I want it to rotate a stepper motor too. I'de very grateful for your help :)
kind regards

I am doing a project,where I need to determine if the image is self taken or not? I am confused whether to use machine learning approach or image processing ? Machine learning approach may not give me very effective results.I am looking for image processing method.Can anyone help me out here..?? I can detect the faces in the image but that is not enough.
Machine learning will work way better in my opinion. With few exemples you should get a correct result. But it won't be perfect.
If you want something more occurate you will need other detailed. For exemple if it is a smartphone application you know if the front camera was used. Maybe another great source of data is the accelerometer because selfies are not taken the same way of regular picture.
If you have faces in the picture and another relevant indicator you probably can state that the picture is a selfie.
Okay the Title can be misleading.
But it´s like this.
I have made an application that constantly sends Images from Client A to Client B.
When Client B receives the image, it will replace the last image.
I currently use Picturebox or Panel, so pretty much:
panel1.BackgroundImage = Image.FromStream((MemoryStream)NetSerializer.Serializer.Deserialize(tt1.GetStream()));
It looks weird though, but as you can se, it will just change the image, when it´s there.
This all goes well up to about 800x600, then it will bottleneck.
I don´t know the update frequency, but i am guessing it´s around 60fps, as i am taking screenshots from my desktop or particular windows.
The bandwidth is not the problem here as long as i don´t use .bmp at 800x600+ of course.
Anyway, my question is, what can i use to replace this way of showing images?
I am guessing something with Directx/OpenGL or something?
Sadly i haven´t found a way to even display an image with that, though then again, i have a hard time understanding it.
I am open for suggestions and examples.
EDIT:
I am thinking, maybe to use WPF to just show the image.
But i don´t know if i can change the background image from a winform, so if it´s possible then i am all ear.
Thanks
I have a book app for the mac , the image sizes for each page are 1024x768. My problem is trying to figure out the display each page.
Should I make it a full screen app - but then might get some horrible
scaling on large monitors.
I could leave it fixed at 1024*768 - this could also be frustrating on really large/small monitors
I've never done this before so have no idea where to start.
Thanks for your time.
It depends on the book format the will be compatible with your app:
If it will use images based books, the fullscreen mode is a bad idea (because of the scalling problem)
If it's structured data books (epub, xml,...), the scalling won't be a problem!
I realize this is not strictly programming related, but hopefully you will let me get away with it.
My group is trying to put together a very short (2 minutes or so) "film" about a new feature to our product. The feature is trying to solve a particular problem a lot of our customers have. We do not want to go with live action for displaying the description of the problem we are trying to solve because we feel that the production value of anything we could come up with would be incredibly low and turn off our viewers. So we would like to make an animation (basically floating clip-art that is animated moving from place to place) while we have someone narrate the problem description.
While flash seems to be a good solution I have some problems with it:
I need to capture this in a movie format like avi
It needs to be captured in 1080p, 720p and regular TV def.
Does anyone have a suggestion for a piece of software that can get me where I need to go?
Free is good, but I think I could get my boss to lay down some scratch for this.
Thanks!
For just some basic here-is-the-screen-this-is-a-slide kinda thing you could use Windows MovieMaker, free and standard.
And here you have some tips on how to create your own screen-captured-AVI file for input.
