Animate a sprite by using two images

I would have thought this was a common desire, but I'll be damned if I can find this.
I simply want to Animate an image by swapping two images back and forth. I tried StoryBoard, but apparently you can't change the source in a storyboard. The only answer I can come up with is a Timer, which I don't think is the best way.
Edit: How do I animate image content in WPF? Came up in the "Similiar Questions" window. And while this will do what I want, it is "hackish" as the OP of it says, and it only swaps two images, what if I wanted a whole sequence of 10 or 20 or 100.

I found another post here on SO whose answer sounds like it could solve your problem: Change an image during animation using storyboard
The problem with this approach is that it also doesn't satify your request for supporting an arbitrary number of images.
I was going to propose a different method that involves databinding the Image Source to the image path, and then in code behind simply changing the path, but I haven't gotten it to work yet.
Here's an article that seems to have an elegant way to handle your requirements: http://www.codeproject.com/Articles/364529/Animation-using-Storyboards-in-WPF
Hopefully that will work for you.

High performance plot control in WPF

I am doing some work for which I need to develop a control, it should be a simple graph that shows several points and two edges.
My problem is that I need to show up to 16k points, with an update rate of 30 Hz. Has anyone done something similar?, and has any advice?.
For example whether to inherit from FrameworkElement or Control (ItemsControl in this case). If the control inherits from FrameworkElememt it may have a better performance drawing the points in the OnRender method but I would miss the Templating feature that comes from inheriting from Control.
Or does there exist another control that can do this out there?
Thanks in advance for your time.

I ended up using InteropBitmap, it is the fatest bitmap rendering class from WPF.
It allows you to map the image that you want to paint (in memory) and then reder it as a Image. This was perfect as i needed to plot points on the screen.
I got great performance (almost 50Hz for 20k points), i also use PLINQ to update the points in memory.
check this article for more details...

Try and read about ZoomableCanvas. I believe it can solve your problem. You can render all the points as small rectangles/ellipses inside the ZoomableCanvas.

Image OCR - Filtering unwanted data

Basically I'm reading vehicle license plates using tessract OCR, however despite being able to emphasise text easily enough via changing contrast, reducing noise an so on, some 'parts' of the vehicle remain on the image which does cause the OCR to throw bad results.
For example take:
I can change this easily enough, such as:
I'm looking to eliminate the edges off each plate, here's another example:
I could remove the edges using pixel manipulation algorithm, however I don't feel it's the right method, and would cause quite a lot of problems.
I've been using the following application to test various methods such as morphology and eliminating the unwanted data, so far I haven't been successful.

However someone with knowledge of this could use the application on the article above to achieve want I'm trying, so feel free to give it a try.
Thanks

Please try to use stroke width transformation concept.
This concept use to segment text from natural images.....

I already did such an algorithm. I just can say that it works great. The secret is, that you need to know that the light is coming just from one side perhaps. You cannot set the image to "black/white" just by using ONE threshold.
Detect the average luminance of parts of the image and use this luminance calculation to set the threshold for each region.
For example, if the left top is lighter, you need a lower threshold to make these parts not to bright. And if the bottom right has low light, you need to set the threshold higher to receive all existing light information.
Then, you need just to drive into the image from each side by using the method:
IsPixelAboveThreshold ?
If it is below, you are on the border, if it is above, you can say you are on the middle of the image with more brightness.

wpf custom control: audiowaveform rectangle with selection slider

I'm working on a c# wpf app in which I want to do something with audio. the irrklang audio library provides me with a pcm decoded 16 bit byte array.
I want to create a timeline control which shows the waveform along the timeline with an overlaying rectangle which the user can drag and click/drag the left and right side to increase or decrease the selection.
It is used to the trim the audio track. I would like the selected min and max to be databindable, the minimum and maximum value of the total track to be bindable.
To clarify here is an image mockup:
I'm not asking for a complete control but tips and suggestions on how to tackle this are more than welcome. Perhaps solutions like this already exist but so far I haven't been able to find it.
I think I need to tackle: the control (zooming, panning and changing the selection) and drawing the waveform in the control
Thanks in advance,

I think you should check out this codeplex project

Refer to Audio WaveForm Drawing Using WPF.
Something based upon WaveFileTrimmerControl.xaml would be useful, it uses related controls PolygonWaveFormControl.xaml & RangeSelectionControl.xaml (links are to the XAML but refer to the CS also). In any case it'd be a good starting point for building a control that exactly meets what you want.
You could override the render method and use primitives which will give possibly better performance; but like anything related to performance I'd try the above approach first which is almost certainly good enough.

XNA/C# Game Settings (Menu?)

It's my first time trying to make anything really interesting in C# and I was trying to make a simple form or game screen where the user could define a custom resolution/screen ratio etc. or to automatically detect the max screen size/ratio and output? its my first game, so I was wondering if it was possible or if there would be any major issues with such, rather than just setting it to 1366x768 (the resolution of all of my computers).
Thanks in advance for any assistance.

You could enumerate through the default GraphicAdapter's DisplayModeCollection property to find the DisplayMode with the max width/height/aspect ratio.
Something like:
GraphicsAdapter defaultAdapter = GraphicsAdapter.DefaultAdapter;
DisplayMode maxMode = defaultAdapter.DisplayModeCollection[0];
foreach (DisplayMode enumeratedDisplay in defaultAdapter.DisplayModeCollection)
{
//Test enumeratedDisplay against maxMode, setting maxMode to enumeratedDisplay if enumeratedDisplay is better
}
Maybe there's a better way, but that's certainly one way you could find the max.
Or, you could take the same DisplayModeCollection and populate a comboBox of sorts or a list, letting the user choose for themselves.
My apologies if the above code doesn't work in that exact form. I can't test it where I am currently

Just set the PreferredBackBuffer to 1366x768 and if the graphics device can handle that resolution you'll get it. otherwise you'll get something scaled down. the xbox will automatically scale if nescessary to support the television being used as well.
