Fix jpegs failing about steganographerpy HOT 4 CLOSED

A possible temp fix could be outputting as a png.

from steganographerpy.

The problem is pack_image assumes that each pixel is length 4, RGBA. For the sample jpegs I have, maybe all jpegs, there is only data for RGB. There is no alpha channel. The correct pixel length needs to be determined to before packing them back up.

Messages cannot be properly read because PILs save function for jpegs is changing the data independently of anything I do. I found that jpegs have quality and subsampling options, but setting those didn't make a difference. There might be other options I can look into. I need to figure out what options to not lose any data. Unfortunately jpegs will require different handling than PNGs, which was the point of using PIL.

Files are now forced to output as png. Any extension the user gives will be ignored and changed to png.
