When file formats not natively supported by Color Factory enters a processing channel, the file will normally be processed as as unknown file.
However, it it possible to enable processing of e.g. HEIC files by using an external processor such as ImageMagick.
First download ImageMagick from their website (external link). You will need the 64 bit Windows version with 8-bit processing. The Portable version (delivered as a zip file) works well without requiring installation.
Navigate to the Color Factory program folder (typically in C:\Program Files\Fotoware\Color Factory 8.0) and create a new subfolder called ExternalConverter.
Copy the entire contents of the ImageMagick zip file to the ExternalConverter folder and restart the Color Factory service.
How it works
Color Factory will now automatically try to use ImageMagick when encountering an unknown file type in a processing channel, and then process the file and deliver it to the output as specified in the channel settings.
