My lambda function watches s3, gets object and crops/resizes to desired sizes, then uploads. I do have the lambda layer for imagemagick, and I've had some success with resize, but it works maybe 10% of the time. These are my imagemagick functions,
exports.resizeImg = async (buf, width, height) => {
return new Promise((resolve, reject) => {
gm(buf).resize(width, height).noProfile().toBuffer((err, buffer) => err ? console.log(err) : resolve(buffer));
});
};
exports.cropImg = async (buf, width, height) => {
return new Promise((resolve, reject) => {
gm(buf).crop(width, height, 0, 0).noProfile().toBuffer((err, buffer) => err ? reject(err) : resolve(buffer));
});
};
exports.monochromeImg = async (buf) => {
return new Promise((resolve, reject) => {
gm(buf).monochrome().noProfile().toBuffer((err, buffer) => err ? reject(err) : resolve(buffer));
});
};
calling the resize or crop as
const resized = await resizeImg(buffer, 200, 200);
then passing the binary/buffer to s3 upload, which is working. If resize works.
I've also tried to write the buffer to fs, but no luck there either.
exports.resizeImage = async (buf, width, height, path) => {
gm(buf)
.resize(width, height, "!")
.write(path + 'output/1111.jpg', function(err){
if (err) return console.dir(arguments)
console.log(this.outname + " created :: " + arguments[3])
})
}
Does imagemagick still work? Or should I just use sharp?
