javax.imageio.IIOException: Missing Huffman code table entry #12

Closed ctrlmaniac closed 6 years ago

ctrlmaniac commented 7 years ago

When I try to embed a watermark from a jpeg image it will work if I don't specify the file extension but it will output the original image to bmp. If I try to save the image into a jpeg file it will throw an error:

javax.imageio.IIOException: Missing Huffman code table entry

See screenshot

I just installed OpenStego on macos 10.13.3 (Java 9.0.4) and have the exact same issue. Valid JPEG file, output file extension jpg

@rjoz Can you attach the source image here?

syvaidya commented 6 years ago

Fixed. Next release would include the same.

syvaidya commented 6 years ago

I have release v0.7.3 now. It should have this fix.

I had to increase memory allocation, but it works now, thanks! :-)
