convert .heic image to jpg image format in laravel - laravel

Question

I have added intervention/image package to convert image format in laravel.
image converted successfully but after uploading image quality was so bad.
Original Image
Uploaded Image
$img =(string) Image::make($image['base64'])
->resize(500, 500)->encode('jpg',100);;
$img = base64_encode($img);

Answer 1

To convert Heic image you have to use imagick, can you use this instead
This is how to install https://ourcodeworld.com/articles/read/645/how-to-install-imagick-for-php-7-in-ubuntu-16-04
try {
$image = new \Imagick();
$image->readImageBlob($image['base64']));
$image->setImageFormat("jpeg");
$image->setImageCompressionQuality(100);
$image->writeImage($targetdir.$uid.".jpg");
}
catch (\ImagickException $ex) {
/**#var \Exception $ex */
return new JSONResponse(["error" => "Imagick failed to convert the images, check if you fulfill all requirements." , "details" => $ex->getMessage()], Http::STATUS_INTERNAL_SERVER_ERROR);
}

Answer 2

A bit late, but I had the same problem.
I managed to do it with the heic2any js library (https://github.com/alexcorvi/heic2any/blob/master/docs/getting-started.md)
I converted the picture on client side, then gave it to the input in client side.
Server is seeing it as it was originally uploaded as jpg.
function convertHeicToJpg(input)
{
var fileName = $(input).val();
var fileNameExt = fileName.substr(fileName.lastIndexOf('.') + 1);
if(fileNameExt == "heic") {
var blob = $(input)[0].files[0]; //ev.target.files[0];
heic2any({
blob: blob,
toType: "image/jpg",
})
.then(function (resultBlob) {
var url = URL.createObjectURL(resultBlob);
$(input).parent().find(".upload-file").css("background-image", "url("+url+")"); //previewing the uploaded picture
//adding converted picture to the original <input type="file">
let fileInputElement = $(input)[0];
let container = new DataTransfer();
let file = new File([resultBlob], "heic"+".jpg",{type:"image/jpeg", lastModified:new Date().getTime()});
container.items.add(file);
fileInputElement.files = container.files;
console.log("added");
})
.catch(function (x) {
console.log(x.code);
console.log(x.message);
});
}
}
$("#input").change(function() {
convertHeicToJpg(this);
});
What I am doing is converting the heic picture to jpg, then previewing it.
After that I add it to the original input. Server side will consider it as an uploaded jpg.
Some delay can appear while converting, therefore I placed a loader gif while uploading.

The heic2any js library helped me accomplish this (https://github.com/alexcorvi/heic2any/blob/master/docs/getting-started.md)
On the client side, I converted the picture, then gave it to the server input. The server sees it as it was originally uploaded as PNG.
$('#files').on('change' , function(){
var total_file=document.getElementById("files").files.length;
for(var i=0;i<total_file;i++)
{
files = event.target.files[i];
var fileName = files.name;
var fileNameExt = fileName.substr(fileName.lastIndexOf('.') + 1);
objURL = URL.createObjectURL(event.target.files[i]);
if(fileNameExt == "heic") {
objURL = await convertHeicToJpg(input , i);
}
})
async function convertHeicToJpg(input , i)
{
var blobfile = $(input)[0].files[i]; //ev.target.files[0];
let blobURL = URL.createObjectURL(blobfile);
// convert "fetch" the new blob url
let blobRes = await fetch(blobURL)
// convert response to blob
let blob = await blobRes.blob()
// convert to PNG - response is blob
let resultBlob = await heic2any({ blob })
console.log(resultBlob)
var url = URL.createObjectURL(resultBlob);
let fileInputElement = $(input)[0];
let container = new DataTransfer();
let file = new File([resultBlob], "heic"+".png",{type:"image/png", lastModified:new Date().getTime()});
container.items.add(file);
fileInputElement.files[0] = container.files;
uploadFile(container.files);
console.log("added");
console.log(url);
return url ;
}
function uploadFile(files)
{
console.log(files);
var error = '';
var form_data = new FormData();
for(var count = 0; count<files.length; count++)
{
var name = files[count].name;
var extension = name.split('.').pop().toLowerCase();
form_data.append("files[]", files[count]);
}
$.ajax({
url:"<?php echo base_url(); ?>Property/upload",
method:"POST",
data:form_data,
contentType:false,
cache:false,
processData:false,
dataType:'JSON',
beforeSend:function(){
//..processing
},
success:function(data)
{
alert('image uploade')
}
})
}
