About Image Colors Detection App
Let's Discuss An App That Can Detect color pixels from images. We Will Discuss Some More Important Coding Logics We Can Use To Detect Colors From Any Image. Through This Blog Post You Were Able to Learn advanced fundamentals of HTML Canvas.
HTML 5 Canvas Element
HTML 5 Canvas in HTML is Used In Many Cases Such as Drawing On Canvas Elements To Build Any Type Of Editor for Client site Editing Apps. To Build This App We Use Canvas To Load images onto the Canvas. We Load Images And Furthur Perform Algorithm To Solve The Problem. Let us Put An Eye On the Furthur Logic
Algorithm Used To Detect Colors
To Perform an Algorithm to Detect Pixels Let's Continue With The Upper Paragraph in Which We Discuss About Canvas Element And Its Uses. In Our Case We Use Canvas To Load images and to Read Image Pixels To further convert Them into RGBA Form RGBA Stands For (RED GREEN BLUE and ALPHA) it is a color representation of colors in digital graphics.
Further Process
First We Get Canvas Data and Then Loop it Using For Loop To Read Pixels Data
In addition the code employs conditional checks to ensure that duplicate colors are counted only once. For instance if there are two instances of the same color the code detects and records it only once in the object preventing redundant counting of identical colors.
Know We Furthur Perform an Algorithm That Sort The Colors Representation in Descending Order For this We Use The Keys from the object using the Object.keys() function and then sort the object keys by using the sort function.
Now we use the slice function in javascript to get the first 5 from the sorted array to print first as a background color and other as a pixel reading format for example #124ed
Steps To Follow
1. Writing HTML Part
2. Creating Beautiful Layout Using CSS
3. Integrating JavaScript
4. Loading Images on Canvas
5. Reading Image Data in Pixel Form
6. Create ColorCounts Object to save pixel data
7. Sorting in Descending Order
8. Slicing from 0 to 5
9. Displaying Detected Colors
10. That's It
