Monochrome tiff to PDF with JPEG2000

[Ivar Snaaijer]

ImageMagick 6.8.7-0 2013-09-18 Q16

When I convert a monochrome tiff image, obtained with

Code: Select all

convert some.txt -monochrome some.tif

to a PDFA with JPEG2000 compression

Code: Select all

convert some.tif  -format pdfa -compress jpeg2000 some.pdf

The resulting PDF contains an image with a gray background.
when I use

Code: Select all

convert some.tif  -format pdfa -compress jpeg some.pdf

The end-result is as expected.

This behaviour does not happen with gif, png or bmp.

Perhaps you need the Jasper delegate library to do JPG2000 compression.
