Hey guys ???
I have developed a web app, that converts images to Pokémon ASCII art style.
website: https://poke.art-creator.net/
github: https://github.com/yuikoito/poke-art-creator
Like this!
※ This article is the eighth week of trying to write at least one article every week.
- Face detection with Tensorflow【React + TypeScript】
- UI Components website Released!
- I made 18 UI components for all developers
- Image Transformation: Convert pictures to add styles from famous paintings
- Developed an app to transcribe and translate from images
- Generate Open Graph images with Next.js and TypeScript on Vercel
- OpenCV in Lambda: Created an API to convert images to Pokémon ASCII art style using AWS and OpenCV
Usage
Visit https://poke.art-creator.net/, then upload an image whatever you want to convert Pokémon ASCII art style.
Just three step.
- Select an image
- Click the Convert button
- Then, wait
You don’t even need to log in, so have a look and enjoy freely!
Loading animation
I used the monster ball as a loading animation.
Thanks to the article of Mr. Temani Afif, I got a good animation.
Image compression
This time, due to the fact that the API processing part is very heavy, the images are compressed on the front side and sent.
The same process is applied in ArtCreator.
The image processing system needs to be as light as possible before sending it, otherwise it will take a lot of time.
The following is a description of the process.
/**
* Canvasの描画して画像をリサイズする
* @param {object} image - Imageオブジェクト
* @param {number} limitWidth - 最大横幅
* @param {number} limitHeight - 最大縦幅
* @returns {string} - base64
*/
export default async function resizeImage(image, limitWidth, limitHeight) {
const aspect = image.width / image.height;
const canvas = document.createElement("canvas");
const ctx = canvas.getContext("2d");
let canvasWidth;
let canvasHeight;
if (image.width > limitWidth || image.height > limitHeight) {
// 規定サイズよりも画像が大きい場合
if (aspect > 1) {
// 横長画像の場合
canvasWidth = limitWidth;
canvasHeight = limitHeight * (image.height / image.width);
} else {
// 縦長画像の場合
canvasWidth = limitWidth * (image.width / image.height);
canvasHeight = limitHeight;
}
canvas.width = canvasWidth;
canvas.height = canvasHeight;
} else {
// 規定サイズ内の場合
canvas.width = image.width;
canvas.height = image.height;
canvasWidth = image.width;
canvasHeight = image.height;
}
ctx.drawImage(
image,
0,
0,
image.width,
image.height,
0,
0,
canvasWidth,
canvasHeight
);
return canvas.toDataURL("image/jpeg", 0.85);
}
That’s it!
Thanks for reading.
This is some kind of a joking app, but I am very happy if you enjoy it!
