    we are considering to use your PDF to image converter in command line mode. Our test shows that the output creates very good quality jpg file. The only concern is that it is in RGB format, not CMYK as per our requirements. Is it the limitation of the software or we missing something in the command line option? Could you please clarify this.
    Thanks

      Thanks for your message, yes, PDF to image converter Command Line is create image files in RGB mode only, it can’t create CMYK image files, however, if this function is important to you, please feel free to let us know, we will support this function to you in a custom-build version.
