Re: EXIF data lost on save

Have you tried exiv2, that are written in C++.
I once tried to use it via c++/CLI, reading from the original and write to newly saved file.
metacopy.cpp would be your help.

Re: RGB555/RGB565 etc are not working

I think it is solved.
It looks -type truecolor is required in this case.

Code: Select all

magick logo: -type truecolor -define bmp:subtype=RGB565 logo565.bmp

Re: How to change tiff compression method in 7.2.0?

Re: All kind of lossless image compression

As I looked the README, I think what you need is -ls option. Check line 138 . I'm not familiar with Visual Studio. In my Mac, I can build jpeg executable, however failed to build library, but I could do a simple check with the generated jpeg command. Example in README is slightly wrong. -ls option r...

convert.exe does not installed from Windows binary in 7.0.0.0.

As http://www.imagemagick.org/script/index.php says current release is 7.0.0.0, I tried to install it from Windows binary.
I tried Q16-HDRI-x64-dll and Q16-HDRI-x86-dll versions and both does not install convert.exe. Instead, it installs magick.exe.
Is it an intentional change?
