    RGB to CMYK conversion using Acrobat's Javascript API

    Paulo Henrique Silva

      I am using Acrobat Javascript API to run a color conversion operation (this.colorConvertPage) but there is no option to mimic all the configurations available in the Color Convert dialog.

       

      For "Preserve Black" I can use the preserveBlack option from colorConvertAction object. However, there is no option on colorConvertAction to do what  "Promote Gray To CMYK Black" does.

       

      Using just Preserve Black all DeviceGray objects are mapped to rich blacks on CMYK, but using Promote Gray To CMYK Black does what I want, no rich blacks.

       

      Any ideas?
