Expected Behavior

The copied bmp file should be exactly the same as the original one.

Current Behavior

For some reason for this bmp file content gets moved/shifted. It does not happen for all the bmp files.

Failure Information (for bugs)

Steps to Reproduce

I've created minial reproducible repo:

git git@github.com:elderapo/jimp-bmp-bug.git
cd ./jimp-bmp-bug
yarn
yarn start

Screenshots

Context

• Jimp Version: ^0.8.4
• Operating System: Ubuntu 14.04
• Node version: v11.10.0, v12.10.0

Failure Logs

The loading system for bmp files seems to be broken. Exact same thing happens when reading bmp file from disk, buffer. Even when file is saved to a different format it still gets shifted.
