Description

PDImageXObject.createFromFile currently relies on file extension to select the correct factory.
Often, file extension is not set or not correct.
It should be better to use the first bytes.

I did something similar here if it can helps: https://github.com/sismics/docs/blob/master/docs-core/src/main/java/com/sismics/util/mime/MimeTypeUtil.java#L26
