blend | A scalable graph database for aiding discovery | Graph Database library

While studying OpenCV, I realized that whenever I blend two images the colors of scr2 have changed in some way(depends on the colors of scr1).

I know this is not an informative and clear way to explain my issue, however; I don't know how to describe this issue since I have no expertise with colors so I would like to show you what I meant with images and code.

The input image: Input image

I am a beginner learning from a tutorial on how to change the colour of a selected area of a picture with a range of colour options.

I can figure out how to change one area, but unsure how to implement the other areas.

What I want to achieve is to click on the selected area, it highlights the border (CSS), then change the colour by using the colour options.

What is the best way to implement this? I'm I correct in thinking maybe a switch statement with onclick to select the specific area of the picture?

I have a WPF app, linked to a SQL-server. I am using the MVVM-light package (I do actually have Prism.Core installed, but I'm not sure if I'm using it or not.... new to MVVM).

There's a DataGrid, bound to an ObservableCollection. I have been trying to implement the PropertyChangedEventHandler, but I can't seem to get it to work.

I have a Delete button bound, and I am able to remove rows, but when I re-open the form, the changes does not carry over.

I tried to change the binding-mode for the DataGrid from OneWay to TwoWay. With OneWay, the changes does not carry over when I re-open the form. With TwoWay, I get this error message when opening the child form (which contains the DataGrid):

System.InvalidOperationException: 'A TwoWay or OneWayToSource binding cannot work on the read->only property 'licenseHolders' of type 'Ridel.Hub.ViewModel.LicenseHoldersViewModel'.'

So, If I then add a set; to my public ObservableCollection licenseHolders { get; }, the program runs, but the previous problem persists, like it did when there was a OneWay mode configuration on the DataGrid.

What do I need to do to get this to work without communicating directly with the Sql-server, which would defy the whole point of using this methodology in the first place?

I have this:

I wanted to make a circle cursor and I copied the code from codepen

I am working in another IDE called Repl.it and so I copied the exact same code from codepen to repl.it (Note: I did use the correct code from codepen by compiling it first)

The code is not working in repl.it

I am not sure what I am missing, but I am pretty sure it has to do with the tags. Any help would be much appreciated.

My Output:

The cursor stays at the top left and does not move at all for some reason

This is the code:

I am investigating if the header in react-navigation can be animated similar to the most widely used social applications like Twitter, etc.

For this purpose recently, I encountered coinbase's example which is given here.

My questions are:

• In general, how the react-navigation header can be animated?
• Specifically, how to blend the Coinbase example with the react-navigation?

Similarly, I could not find any clean example for react-navigation usage with react-navigation-collapsible either.

So any atomic example code is appreciated.

I got a button (using MaterialDesign theme) in a WPF form button that is not styling correctly, where am I going wrong?. The button in the DataGrid is fine. I tried near Window on mainWindow doing Foreground="white" but when I take the theme off everything returns to nornal WPF form with the text colour (lower right) missing

I'm trying to read a file from STDIN, process it with paper.js and return the results.

To get there I first tried to do it by reading in a file from the fs like this:

Im tring to create a glitch image animation effect.

I use layers with mix blend modes, and clip paths. but how can I cut part of the main image?

Since I want to achieve the effect of displacing a piece of the picture. Main background can be image too, thats why I can't use background-color in layers.
