Declaration
property Params[idx: integer]: TIOParams;
Description
Provides access to the
TIOParams object for the image
idx.
The parameters are updated when loading from files or streams. You can modify these parameters before saving images.
Note:
◼If
ParamsEnabled is false,
Params are not updated when
assigning or
appending◼To propogate compression params to all frames of a multi-frame image, use
DuplicateCompressionInfo// Change the compression method for a TIFF file
MBitmap := TIEMultiBitmap.Create();

MBitmap.LoadFromFile( 'C:\MyImage.tiff' );
MBitmap.Params[ 0 ].TIFF_Compression := ioTIFF_G4FAX;
MBitmap.DuplicateCompressionInfo();
MBitmap.SaveToFile( 'C:\OutImage.tiff' );
MBitmap.Free;
// Which is the same as:
MBitmap := TIEMultiBitmap.Create();
MParams := TIOMultiParams.Create();
MBitmap.LoadFromFile( 'C:\MyImage.tiff', MParams );
for i := 0 to MBitmap.count do
MParams[i].TIFF_Compression := ioTIFF_G4FAX;
