[BUG] Unable to correctly determine the image format type of the base64 encoded jpeg2000 image

[typelogic]

This bug is detected in branch 1.1.2. I also scan the code, it is also in branch 1.1.3.

Mismatch image type header from actual image type content

To Reproduce
It can only be reproduced when integrating a third-party component. I believe the offending line is in the following:

• For branch 1.1.3 it is in line 572 of PrintServiceImpl.java.
• For branch 1.1.2 it is line 551 of PrintServiceImpl.java.

The image type is hardcoded as data:image/png;base64. The problem only manifests when integrating a third-party component which tries to convert the base64 encoded image content to other format. If the image content is of type jpeg2000 format, then the header should describe it as such.

Expected behavior
The header should describe the image type in order for third-party component to properly handle the image content
