TIOParams.TIFF_PhotometInterpret
TIOParams.TIFF_PhotometInterpret
Declaration
property TIFF_PhotometInterpret: TIOTIFFPhotometInterpret;
Description
Specifies the Photometric interpretation of a TIFF image.
Note: If you are using a
TIEMultiBitmap or
TImageEnMView, you can use
DuplicateCompressionInfo to propogate the parameter to all frames
Default: ioTIFF_RGB
// Save TIFF as 32bit gray-scale (ie32f)
// Note: Compression must be: ioTIFF_UNCOMPRESSED, ioTIFF_LZW, ioTIFF_PACKBITS or ioTIFF_ZIP
