TIEBitmap.ParamsEnabled

TIEBitmap.ParamsEnabled


Declaration


property ParamsEnabled: Boolean;


Description


If ParamsEnabled is true, then this object stores the Input/Output parameters (meta-data) for the image, which can be accessed via Params.
Default: False.

Note: ParamsEnabled should only be used when TIEBitmap is being used as a stand-alone object. When it is attached to a TImageEnView or TImageEnMIO, use TImageEnIO.Params instead.


Examples


// Reduce the size of a JPEG image
aBmp := TIEBitmap.create;
aBmp.ParamsEnabled := True; // Load params with the image
aBmp.Read( 'C:\MyImage.jpeg' );
aBmp.Params.JPEG_Quality := 70;
aBmp.Write( 'C:\OutImage.jpeg' );
aBmp.Free;

// Which is the same as:
aBmp := TIEBitmap.create;
aIOParams := TIOParams.create;
aBmp.Read( 'C:\MyImage.jpeg', aIOParams );
aIOParams.JPEG_Quality := 70;
aBmp.Write( 'C:\OutImage.jpeg', aIOParams );
aIOParams.free;
aBmp.Free;

// Load the third image in a TIFF and save it to JPEG
aBmp := TIEBitmap.create;
aBmp.ParamsEnabled := True; // Load params with the image
aBmp.Params.ImageIndex := 2;
aBmp.Read( 'C:\MyTiffDoc.TIFF' );
aBmp.Params.JPEG_Quality := 70;
aBmp.Write( 'D:\Page3.jpeg' );
aBmp.Free;
