Edit TIFF metadata in VFP9?

[rsmock21]

I am trying to modify the metadata in a TIFF file using VFP9, specifically the XResolution and YResolution tags, and either update the file or save to a new file. So far I haven't had any success. I tried using the gpImage class from _GDIPLUS.vcx, and I can view the VerticalResolution and HorizontalResolution properties of the image file, but I don't see any way to adjust it.

Does anyone have any ideas? Or third party tools that would accomplish this? Thanks.

It should be doable via gdiplus:

GDI+ provides a uniform way of storing and retrieving metadata from image files in various formats. In GDI+, a piece of metadata is called a property item. You can store and retrieve metadata by calling the SetPropertyItem and GetPropertyItem methods of the Image class, and you don't have to be concerned about the details of how a particular file format stores that metadata.

If _gdiplus.vcx doesn't offer that, give VFPX a try, to be more precise GDIPlusX:
