monochrome | A fully responsive Kirby CMS theme | Content Management System library

I am pretty new to js, and I am building a color scheme generator as a solo project. I am now stuck on select the html element that created from dynamically. I tried to select both label and input element below, using document.getElementByClassName but it gives me 'undefined'

I wanna select both label and input elements and add an click eventListner so that they can copy the result color code from that elements.

The following creates a transparent NSWindow with a ContentView that uses blendMode to create a colour filter overlay effect so that everything behind the window appears blended (grey monochrome in this instance). It's working as expected except when the window is not active or being dragged in which case the ContentView flickers between normal (no blending) and blended; the ContentView is also showing dirty in some cases, i.e. when inactive ContentView is partially rendering and not fully updated.

Am I missing something in terms of ContentView life-cycle / refresh in relation to NSWindow events, is my NSWindow setup correct, or is this a potential bug? Essentially, the issue doesn't occur when blendMode isn't used, as testing with a transparent NSWindow and semi-opaque ContentView behaves normally.

I'm using Xcode 12.5.1 on Big Sur 11.6.2, and targeting 10.15

Code to reproduce using the AppKit App Delegate lifecycle template:

I am trying to run test cases in cucumber for testing a mobile application using IntelliJ. The project code is in kotlin and I am using appium server to run the test case on android emulator. The test cases were working fine but after taking last pull request from project repository on github, the test cases are not running Cannot find cucumber cli main file

I am getting Error: Could not find or load main class cucumber.cli.Main

Example of numbers

I am using the standard pytesseract img to text. I have tried with digits only option 90% of the time it is perfect but above is a example where it goes horribly wrong! This example produced no characters at all

As you can see there are now letters so language option is of no use, I did try adding some text in the grabbed image but it still goes wrong.

I increased the contrast using CV2 the text has been blurred upstream of my capture

Any ideas on increasing accuracy?

After many tests using the suggestions below. I found the sharpness filter gave unreliable results. another tool you can use is contrast=cv2.convertScaleAbs(img2,alpha=2.5,beta=-200) I used this as my text in black and white ended up light gray text on a gray background with convertScaleAbs I was able to increase the contrast to get almost a black and white image

Basic steps for OCR

1. Convert to monochrome
2. Crop image to your target text
3. Filter image to get black and white
4. perform OCR

I want to use Pygame's freetype module to load a colorful emoji via its unicode. Unfortunately I only get a monochrome image with the outline of the emoji:

Minimal, Reproducible Example:

When trying to write some routine in x86 assembly for a boot loader, I came across a bug where when a division error happened, the program would get stuck in an infinite loop. Through investigating, I found out that calling int 0 would go through the exception handler normally and then continue execution of the rest of the program. Writing my own exception handler for x86, the return address when a division error exception happened was the address of the instruction, meaning that it would just execute the division over and over looping forever. Is this normal behavior or a bug with Virtualbox/my cpu specifically?

I need to get a options ( for example, resize_to_limit: [300, 222], kuwahara: '3%' ) of variant Active Storage (Ruby on Rails 6.1) from the db. My decision:

I'm trying to create a PDF file containing a monochrome 1-bit image, but configure the image to be transparent where it contains white pixels (so that content under the image is visible). The image uses the DeviceGray color space, and BitsPerComponent is 1.

I'm using the Mask entry with an array specifying the color range which should be masked. My copy of the PDF spec calls this "Colour Key Masking". Since the image is bitonal, this color range is just [1 1] (white).

However, I simply can't get this to work. The content under the image never displays. I've tried tweaking the range values, changing the image filter, tweaking the surrounding graphics state -- all to no avail.

The only thing that has worked has been to change the image color space from DeviceGray to DeviceRGB and tweak the Mask ranges accordingly, but that would increase the size of these images in the PDF file, which I cannot do.

What is the correct way to use color key masking on bitonal DeviceGray images?

Here's the image that I think should work, but does not:
