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

Examples

// Save TIFF as 32bit gray-scale (ie32f)
// Note: Compression must be: ioTIFF_UNCOMPRESSED, ioTIFF_LZW, ioTIFF_PACKBITS or ioTIFF_ZIP
ImageEnView1.LegacyBitmap := false;
ImageEnView1.IEBitmap.PixelFormat := ie32f;
ImageEnView1.IO.Params.BitsPerSample := 32;
ImageEnView1.IO.Params.SamplesPerPixel := 1;
ImageEnView1.IO.Params.TIFF_PhotometInterpret := ioTIFF_BLACKISZERO;
ImageEnView1.IO.Params.TIFF_Compression := ioTIFF_UNCOMPRESSED;
ImageEnView1.IO.SaveToFileTIFF('D:\GrayTiff32.tiff');

// Save a PNG with alpha to TIFF
ImageEnView1.IO.LoadFromFile( 'D:\Alpha.png' );
ImageEnView1.IEBitmap.PixelFormat := ie24RGB;
ImageEnView1.IO.Params.TIFF_PhotometInterpret := ioTIFF_RGB;
ImageEnView1.IO.Params.SamplesPerPixel := 4;
ImageEnView1.IO.Params.BitsPerSample := 8;
ImageEnView1.IO.Params.TIFF_Compression := ioTIFF_UNCOMPRESSED;
ImageEnView1.IO.SaveToFile( 'D:\Alpha.TIFF' );
