Well Watch a basic simple Image crawler in Node JS on my Youtube Channel I decided to Master Node JS as its similar to java script and its very popular Well I have been doing a lot of web scrapping projects in Python now its Time to explore other programming languages. I have recently also released a Websites for API I Develop Python Based Cross Platform Desktop Application, Webpages, Software, REST API, Database and much more I have more than 2 Years of Experience in Python. I have completed by Bachelor in Electronic Engineering and my Double master’s in Computer and Electrical Engineering. let me introduce myself in short Hello! I’m Soumil Nitin Shah, a Software and Hardware Developer based in New York City. * 0.Hello! It has been a long time since I wrote my last Blog. Set the green value to 75% of its original value (i.e.Suppose we want to change the yellow flowers to look orange.Now we can express what new value we want in terms of the old value, like "triple the red value", or "set the red value to 75% of what it was". tRed(pixel.getRed() * something) īefore we could only express ideas like "set the red value to 200". Bottom line, we'll use this pattern a lot:.double the red value (with set/get pattern): Now can express relative color number changes.Loops With Expressions - Set/Get Patterns If setRed() is called with a value a greater than 255, it just uses 255, and likewise if a value less than 0 is passed in, it just uses the value 0. functions automatically limit the value set to the range 0.255. This expression is evaluated first, resulting a number such as 240. The code pixel.getRed() * 2 is an expression, which is whatever the old red value was multiplied by 2. Whatever the red value, the line doubles it.Result is changing the pixel red from 120 to 240.Evaluates the pixel.getRed() * 2 expression. Q: What does running the line above do to the pixel?.The net effect is to double the red value of the pixel from 50 to 100. The second line computes red * 2 (100 in this case), and sets that value back into the pixel as its new red value. Say in this case that the red value is 50. The first line retrieves the red value from the pixel and stores that value in an variable named red. For example, the above code snippet doubles the pixel's red value. The pixel.getRed() can be combined with tRed( number) to operate on a pixel. This is a more realistic sort of operation.Suppose we want to double the red value of a pixel.Set/Get Pattern: combine tRed() and pixel.getRed() A good example of the inflexible nature of computers. The syntax requires that calling a function includes the parenthesis, even if there's nothing inside the parenthesis. Notice that calling, say, pixel.getRed() has the pair of parenthesis () after it. Here is an example of getRed() - get the red number out of a pixel, store it in a variable named "red".
