CROSSFAD BACKGROUND IMAGE CYCLER CODE
Scanning you code quickly, there are some similarities with yours and mine, but I do see differences as well (for instance that Task.Delay). Which is exactly what happens in the if statement. What it SHOULD be is Background.Source = (AllImages.Count - 1) and App.Index = 0. So now I just make use of while: if (App.index 0)Īt the moment, when the first image gets shown in the loop, it only shows it for a very small time, and then jumps to the next item in the fade very quickly.Īt this point I imagine Background.Source = first image and App.index = first image + 1. I realised using a for statement was silly because when the while() returns false it would still cycle through each iteration before finishing. I've actually just made a small modification. Are you suggesting that I use this to create a pause between each foreach statement (which loops under the while() statement) to see if that makes a difference? Can you elabroate or provide resources on what you mean by using multiple threads? I am aware that using Task.Delay with an async method allows the programming to continue running by generating an additional thread to run Task.Delay. Since I'm a beginner to programming in general, I'm not familiar with utilising multiple CPU threads. By that I mean that the program actually behaves exactly as it should, it's just for some reason Background.Source and PreviewImage.Source take on images that they shouldn't do. Also, when the error occurs, it definitely looks like something is wrong in the code. The largest draw was actually Hard Disk access, but I think that was because the images I provided where too large, so I scaled them down and it seems fine. However, I have used Windows Task Manager to track the performance, and the application (when looping) only uses about 30% of the processor power.
I am coding on a i5 Quad Core PC, but running the programme off a laptop (there are two I have tried it on). PreviewImages.Source = new BitmapImage(new Uri(Convert.ToString(Slides._image))) Īnd when the user exits: else if (e.Key = .OemPeriod)
CROSSFAD BACKGROUND IMAGE CYCLER MANUAL
When the user exits the manual slideshow screen, App.timer = true void MainWindow_KeyDown(object sender, e) When the user launches this screen from the slideshow, it sets App.timer = false to stop the image transitions in the background at the next foreach statement.
It may be relevant to add that on a different window, I use a different list of images that you can navigate through by clicking manually.

I would attach the source code, but Daniweb is saying I can't attach RARs, so not sure how to share it with you.
CROSSFAD BACKGROUND IMAGE CYCLER TV
If I connect the laptop the programme is running on to a TV via HDMI (which is what I've designed this to do), then the error always happens. Having said that, the error is still there. I've experimented with decreasing the Task.Delay to simulate a lot of transitions in a short amount of time, but even when I do that everything still works. Like I said, when I start it up everything works fine.
The problem is that I can never seem to replicate the issue. That makes me think its an issue with the App.index++ Is someone able to tell me if there are any mistakes here? I find it incredibly odd that it starts by working fine, but only after a while starts going wrong. The code I am using for this is: public async void transition()Įnvironment.GetFolderPath())) HOWEVER, my issue is that for some reason I cannot explain, after a while operating the code (say 10 minutes) instead of showing a ncie cross fade, the code plays up and starts skipping images and the cross fade completely breaks, instead it appears like Background.Source becomes some random image, so the result is an instant snap to an unrelated image, followed by an instantaneous the fade in of the "correct" image.
CROSSFAD BACKGROUND IMAGE CYCLER SERIES
The script then leads onto the next image in the series after a Task.Delay. Because I have a DoubleAnimation fade in effect, it will appear like image 1 and 2 are crossfading. The idea is that Image 1 = Background.Source whilst PreviewImages.Source = Image 2. In order to simulate a cross-fade effect, I have two image objects on my canvas, PreviewImages and Background. At the moment, the picture folder is simply My Pictures. When I the F5 button, a second window pops up at fullscreen, and I want it to cycle through all the images shown in the previous screen. At the moment I have one window, with a list of images displayed in a ListBox. Over the past few weeks as an excerise I've been trying to create a C# image viewer.
