Failure on Webkit Mac App

[ozgurozkan123]

Tested on Safari, Chrome and Webkit Mac app.

The file on this link: https://reminis-pip-pab.s3.amazonaws.com/DW_ET.jpg

It gives "Invalid JPEG metadata: Invalid segment size." error on Webkit Mac App. It is in function parseMetaData(file, callback, options, data) line 137

It gives a strange file attached below on load. It's 4 bytes jpeg. and canvas.toBlob gives null blob.

There is no problem with Chrome and Safari with the same code.

Hi @ozgurozkan123, sorry for the late reply. Unfortunately the file you provided is not accessible anymore. Can you upload it somewhere more permanent so we can have a look?

I have the same problem with all my images =(

Chrome on Windows

@darkvovich The Invalid JPEG metadata: Invalid segment size. error is logged if the length defined in a JPEG APPn segment exceeds the size of the maxMetaDataSize option or the size of the file. It seems like the image blob generated from a Canvas for your picture contains a JPEG APP2 segment that is larger than what is defined as maxMetaDataSize for image head replacement (currently 256 bytes). I'm not sure why the Canvas generated image contains a bigger sized meta data segment for your image (since canvas data does not retain JPEG meta data), but I'll release a fix that raises this to 1024 bytes.
