Hi,
UPDATE: So it works on a Mac but fails on Windows64
so I'm trying to use your library to convert some relatively large SVG files (Between 70MB to 150MB). It seems to be able to handle 50mb files fine. I'm also converting them to pretty large PNGs (4800 by 4250). The code is attached below along with an example SVG you can try. This is the error message I get.
at ChildProcess.exithandler (child_process.js:275)
at emitTwo (events.js:126)
at ChildProcess.emit (events.js:214)
at maybeClose (internal/child_process.js:925)
at Process.ChildProcess._handle.onexit (internal/child_process.js:209)`
async function runExport(files) {
let promiseChunk = []
for (let i = 400; i < files.length; i++) {
console.log('Starting iteration ' + i)
const input = fs.readFileSync(files[i])
const saveName = 'ouput_' + i + '.png'
let svgPromise = svg2png(input, { width: 4800, height: 4200 })
.then(buffer => {
fs.writeFile(saveName, buffer)
if (i+1 == files.length){
var end = new Date().getTime()
console.log((end-seconds)/1000)
}
}).catch(e => console.error(e));
promiseChunk.push(svgPromise);
if (i % maxPerIteration === 0){
await Promise.all(promiseChunk)
}
}
}
`
What have I done to remedy this?
I've increased:
'--max-old-space-size=4096'
I've also looked into the heap using heapsnap shot and it seems it is only using like 350 Mb in these cases. (I could paste these later if it is useful). So I'm not entirely sure what is wrong. Some help would be extremely nice!
