How can I suppress the display of TIFF warnings?

Many types of TIFF files are "variants" on the industry standard TIFF format and may not precisely match TIFF image specifications. Very often, tags are missing from the image which are required for full conformity with the TIFF spec. But as you probably know, that doesn't mean the image is "bogus". Information in the missing tags may be reconstructable from other information contained within the file.

By default, DaVinci displays corresponding warnings when importing files with missing tag data. You can suppress this warning on import by adding IPF_NOWARNINGS to existing flag values.

What exactly is required to redistribute the DLLs with my product?

When you register your copy of DaVinci, you must specify your company name and/or the company name of the customer for whom you are developing. Once the copyright holder for the end product has a valid license, you can include DaVinci DLLs with any software developed by or for that copyright holder which makes use of DaVinci functions.

There is one exception. If you wish to develop a software tool (specifically a DLL, OCX or similar product designed to allow others to develop their own software) and this tool is based on, or requires, DaVinci, and you want to allow your users to distribute DaVinci components with their software, then you will need to contact our marketing team for special-case licensing terms.
