Frontend javascript module for resizing and compressing images
I write this library in client side but it throws error also i added the script for imagecompressor
<script src="node_modules/image-compressor/image-compressor.js"></script>
Let me know if any.
I installed npm image-compressor.
my code is
router.put('/person', function(req, res, next) {
if (req.access === false) {
res.send(401);
}
var encodedImage=""
var form = new formidable.IncomingForm();
form.parse(req, function(err, fields, files) {
var fileSize = files.attachment.size;
if(fileSize!=0){
var filePath = files.attachment.path;
var fileName = files.attachment.name;
var fileType = files.attachment.type;
encodedImage = imageBase64.local(filePath);
var imageCompressor = new ImageCompressor;
var compressorSettings = {
toWidth : 100,
toHeight : 100,
mimeType : 'image/png',
mode : 'strict',
quality : 0.6,
speed : 'low'
};
imageCompressor.run(filePath, compressorSettings, .proceedCompressedImage());
}
function proceedCompressedImage(compressedsrc){
console.log("---==-=-=-=-==-=-="+compressedsrc)
}
How do i solve this issue ?
I want to use this module in react. However, I am getting error Error: Source can not be loaded. I installed via npm install image-compressor
import "image-compressor";
var ImageCompressor = new window.ImageCompressor();
var compressorSettings = {
toWidth: 100,
toHeight: 100,
mimeType: "image/png",
mode: "strict",
quality: 0.6,
grayScale: true,
sepia: true,
threshold: 127,
vReverse: true,
hReverse: true,
speed: "low"
};
const proceedCompressedImage = compressedSrc => {
console.log("Compressed Src: ", compressedSrc);
};
export const compressImg = imageSrc => {
ImageCompressor.run(imageSrc, compressorSettings, proceedCompressedImage);
};
quality parameter values between 0.1 to 0.9 doesn't seem to work(for mime type : PNG). Not even in the provided Demo. I've tried rendering images with parameters 0.1 and 0.9 , both of them returned images of same size. Please help @powerbot15
I got this error when I compressing my image
Uncaught DOMException: Failed to execute 'getImageData' on 'CanvasRenderingContext2D': The canvas has been tainted by cross-origin data.
