WAVE

I developed an app using rshiny, https://smandape.shinyapps.io/mmdit/. I am trying to make it WCAG 2.1 accessible. I am using WAVE (Web accessibility evaluation tool) to check for accessibility. Currently, the errors popping are related to 'missing form label'. These errors are specifically for the code fileInput or rabiobuttons (5 errors are on Data import tab). For example, around the following code. WAVE shows the error for the placeholder for fileInput.

I am currently a bit stuck! Lets say, have a grid of shapes (nested For-Loop) and I want to use a wave to animate it. The wave should have an offset. So far, i can achieve it. Currently the offset affects the Y-axis … But how can I manage to have a RADIAL offset – you know – like the clock hand, or a radar line… I really would like the offset to start from (width/2, height/2) – and then walks around clockwise. Here is my code and the point where I am stuck:

I am trying to install hpctoolkit using Spack. In order to do that, I executed :

I'm new to F# interactive notebook and XPlot.Plotly.

I tried the following code in the hopes to get a nice sine wave shown

I'm trying to work with an old version of DirectX (8.1) and I'm finding the documentation more than a little confusing. It feels like the IDirectMusicPerformance8 interface is for MIDI playback, as it has various MIDI-related methods on it, but various parts of the documentation suggest that it can be used to play back WAV data as well. For instance, the tutorial says that you call InitAudio on the performance, and it states "Wave files require only a single performance channel, and MIDI files require up to 16".

So is it for MIDI or can it be used for WAV?

If it can be used for WAV, I'm even more stumped, because I'm initializing it, running performance->PlaySegment(segment, 0, 0, NULL), getting a success response, but the audio is silent.

I am trying to generate and draw a sin waves. I am using this formulae that I found online y = Amp * sin(2 * PI * frequency * time + shift)

I uploaded my code and svgs to this github repo.

I have some svgs of some circles, blobs and triangles. I am trying to make the circles shake, like how the guy shakes in this code pen when you hover on him, I am trying to make the blobs move like waves like in this code pen, and I'm trying to make the triangles spin around. The blobs and triangles are not responding at all, even though I can see that they have the styling applied when I inspect the html. The circles have some effect, but not the one I want.

Here is the code for each

I am trying to distort a grid of images that are displayed randomly when the mouse is clicked.

I have the grid and the random when click.

I have accomplished the distorsion I want when I have only one image.

Now I have to merge both codes together, but I can't figure out how to do it when the PImage is an array.
