What does identify -verbose copy_check.tiff tell you about the resulting image. It may be 8/1 bits or 16/1 bits palette or truecolor. Try adding depth 1 and compress group4 or fax. What version of Imagemagick are you using and what OS/platform? Please always provide your IM version and platform ...

trying to save binary image:

Image image;
image.size(Geometry(10000,10000));
image.type(BilevelType);
image.write("D:\\copy_check.tiff");

but after saving file has size 195 MB. Why? After all, if it was converted into a binary, it's size must be about 10000*10000*1bit =10 MB.

depth can be 1 if the output file format supports it monochrome converts to black/white (1-bit) See http://www.imagemagick.org/script/command-line-options.php#monochrome You can also use the equivalent of -type bilevel Or you can use the equivalent of -threshold to convert to 1-bit result. All ...

I have already seen that and If I correctly understand, depth can be only from 8 to 32 bit, and what about monochrome(), it looks like grayscale transform, so I need exact answer

Is there an opportunity to construct binary (1bit) images and convert other images to this format using c++ api? I coudnt find any information about this.
