Examples
// Convert a PNG to JPEG at 90% quality
ImageEnView1.IO.LoadFromFile('D:\image.png');
ImageEnView1.IO.Params.JPEG_Quality := 90;
ImageEnView1.IO.SaveToFile('D:\output.jpg');
// Save a TIFF with CMYK
ImageEnView1.IO.LoadFromFile('D:\image.tif');
ImageEnView1.IO.Params.TIFF_PhotometInterpret := ioTIFF_CMYK;
ImageEnView1.IO.SaveToFile('D:\image-cmyk.tif');
// Set color-mapped 256 colors
ImageEnView1.IO.Params.BitsPerSample := 8;
ImageEnView1.IO.Params.SamplesPerPixel := 1;
