Notarization is a security feature for macOS apps outside the Mac App Store, command line tools, kexts, and so on. The developer registers the developed programs to the Apple Notary Service. When you launch the program, macOS checks it w...

You might want to measure the elapsed time to display the transfer speed or determine the remaining time for the heavy-weight processing to complete. This article introduces a code sample that demonstrates how to measure elapsed time usi...

No window appears when I attempt to display one using OpenCV's imshow() function in Python. When running from a Terminal app, there is no problem. However, it still does not appear when executed from the terminal tab within Pycharm. This...

Python and OpenCV are used to develop services and applications using Computer Vision, Machine Learning (ML), and Artificial Intelligence (AI). It is also used to learn about these technologies. Once the development environment is set up...

This article is part of a series focused on creating color picker in SwiftUI. Previously, we completed the color picker itself. This article concludes the series by demonstrating the color picker in a sample application. 【What we make】...

This is a series of articles on creating a color picker in SwiftUI. In the previous articles, the model was partitioned by channel, with gradient and current channel value information being distinct entities, thereby complicating the dyn...

This is a series of articles on creating a color picker in SwiftUI. In this article, we'll implement a color preview, drawing upon the values selected using the RGB channel sliders we built in the previous articles. Moreover, we need to ...

This is a series of articles on creating a color picker in SwiftUI. In this article, we will implement a process that allows knobs to be moved with a drag (pan) gesture. 【Use DragGesture in SwiftUI】 In UIKit, the gesture of tracing a f...

This series of articles resolves around creating a color picker in SwiftUI. Initially, I envisioned the code to be on a smaller scale and, thus, added code with minimal organization. However, this approach led to a convoluted codebase. S...

This is a series of articles on creating a color picker in SwiftUI. In this article, we aim to implement the code that enables tapping on the gradient view of the color picker to set RGB values. 【To support tap gestures in SwiftUI】 To ...
