[magick-users] Bug in TIFF JPEG compression

[Andreas Müller]

Hi,

I've detected that there seems to be still a bug in saving jpeg compressed
tiff images. I createt a bug demo:
http://www.universalware.de/download/bug1.zip

The source is in "bug1.dpr". There you will see that:
- demo1.tif is created using JPEGCompression/80%
- demo2.tif is created using Group4Compression
- demo3.jpg is created using JPEGCompression/80%

demo1.tif and demo3.jpg should be nearly the same size because of equal
compression.
But demo1.tif is 922.813 bytes and demo3.jpg is 292.478 bytes.

Best regards,
Andreas
