ImageGear Professional for Windows ActiveX
Setting TIFF Tags
| ImageGear Professional v18.2 > User Guide > Using ImageGear > Working with TIFF Files > Setting TIFF Tags |
ImageGear Professional ActiveX provides two ways to set and modify TIFF tags. You can modify or set some of the TIFF tags using IGFormatParams Object control parameters (see Working with Format Filters) and Image Processing functions (see Image Processing). When you use these techniques, ImageGear automatically transfers the setting your application specifies into the TIFF tags. You can modify or set all of the TIFF tags using the metadata processing Events (see Working with Non-Image Data).
The following table summarizes the first approach.
| Tag | Property/Method to Set |
|---|---|
| IGTAG_TIF_ORIENTATION | IGPageDisplay Object.Orientation property |
| IGTAG_TIF_XRESNUMERATOR | IGPage Object.CopyImageResolutionFrom |
| IGTAG_TIF_YRESNUMERATOR | IGPage Object.CopyImageResolutionFrom |
| IGTAG_TIF_DATETIME | IGFormatParams Object.GetParamCopy("DATETIME") |
| IGTAG_TIF_ARTIST | IGFormatParams Object.GetParamCopy ("WRITE_CLASS_F") |
| IGTAG_TIF_DOCUMENTNAME | IGFormatParams Object.GetParamCopy ("DOCUMENTNAME") |
