This code inverts the image
Code: Select all
MagickBooleanType status;
MagickWand *magick_wand;
MagickWandGenesis();
magick_wand=NewMagickWand();
status=MagickReadImage(magick_wand, "c:\\test.bmp");
MagickSetImageCompression( magick_wand, FaxCompression );
status=MagickWriteImages(magick_wand, "c:\\out.tiff",MagickTrue);
magick_wand=DestroyMagickWand(magick_wand);
MagickWandTerminus();
Do i need to invert the bits before the conversion? This seems wrong.

Works for me with IM 6.4.2-5 Q8.

I can send you the bmp I am using. My email address is smith_kurtathotmail.com( had to take out the @ sign for it to appear correctly...you get the idea.) so if you send me an email i can send you the file. I am using the same version you are.
also, when I read two images and write them back as a multi-tiff only the first image is in G3 format.
Code: Select all
status=MagickReadImage(magick_wand, "c:\\page1.bmp");
status=MagickReadImage(magick_wand, "c:\\page2.bmp");
MagickSetCompression( magick_wand, FaxCompression );
status=MagickWriteImages(magick_wand, "c:\\out.tiff",MagickTrue);
//if (status == MagickFalse)
// ThrowWandException(magick_wand);
magick_wand=DestroyMagickWand(magick_wand);
MagickWandTerminus();

Can you post it on a website so I can download it from there?

I really don't have that option.
Any idea why all the images in the resultant tiff are not G3 encoded? This seems to be a bug.
Also, I just tried with 9 bmp images and the resultant TIFF was the same. The first image was G3 encoded. The rest were non-compressed. And even more peculiar was the 9th image added was the second in the sequence in the output tiff. Why would the images be out of order when written?
