1) when you send an empty msg.payload, the image is blanked but the node.status still shows the file name. You can fix this by sending a blank msg.file name.
-- this can be corrected by adding a line to this code snippet in image.js (lines 81-85):
// Reset the image in case an empty payload arrives
if (!image || image === "") {
sendImageToClient(null, msg);
return;
}
by changing it to this:
// Reset the image in case an empty payload arrives
if (!image || image === "") {
node.status(""); // blank out the status <==== this line added
sendImageToClient(null, msg);
return;
}
2) if you check the 'Resize images on server side' option, the status is not filled in with the path to the image. This can be corrected by commenting out a line in this code snippet (lines 93-106):
if (node.thumbnail) {
if (isJimpObject(image)) {
// Use the input Jimp image straight away, for maximum performance
resizeJimpImage(image, msg);
}
else {
if (!Buffer.isBuffer(image)) {
// Convert the base64 string to a buffer, so Jimp can process it
image = new Buffer.from(image.replace(/^data:image\/[a-z]+;base64,/, ""), 'base64');
}
oldimage = image;
Jimp.read(image).then(function(jimpImage) {
resizeJimpImage(jimpImage, msg);
// node.status(""); <==== comment out this line
