Questions and postings pertaining to the development of ImageMagick, feature enhancements, and ImageMagick internals. ImageMagick source code and algorithms are discussed here. Usage questions which are too arcane for the normal user list should also be posted here.
When installing from pre-compiled distribution it works. When compiling myself it doesn't. Other formats JPG, GIF work fine.
Same machine. Want to modify, but tested before I did.
Is there a new no-defaulted option on converting to the mono format. The converted image is a b/w JPG.
The follow test is always returns same result. All pixels are processed.
From mono.c WriteMONOImage
Code: Select all
if (image->endian == LSBEndian)
if (PixelIntensity(p) < (QuantumRange/2.0))
if (PixelIntensity(p) >= (QuantumRange/2.0))

We can reproduce the problem you posted and already have a fix. Look for a point release of ImageMagick with the fix within a few days.
Thanks the new post fix it. I am currious what was done to fix. I have copied mono.c to create a new modual, suffers same problem and mono used to.
