You can find plugins for CorelDRAW graphics suits that allows users to produce Tajima embroideries (.dst) right in the program without the need for a special embroidery software. This is especially handy if you try to convert some of the less used images like .dcr camera raws from Kodak cameras.
Another option would be to first export DCR format to formats supported in embroidery programs and then export it to Tajima format.
