LibWebP is a Google open source library that allows ImageEn to read and write WebP files.
You can create lossless lossless WebP files, as well as varying the compression.
Codec version information is available with WIC_CodecInfo

Notes
◼ The LibWebP plug-in requires yout to ship iewebp32.dll (for 32bit applications) or iewebp64.dll (for 64bit applications)
◼ It is included in the \DLL\ folder of the ImageEn installation
◼ The plug-in must be registered once by your application

Demo

Examples

// Register the WebP Plug-In
IEGlobalSettings().RegisterPlugIns([ iepiWebP ]);

// Save an image to a WebP file with 80% quality
ImageEnView1.IO.Params.HDP_ImageQuality := 0.80;
ImageEnView1.IO.SaveToFileWebP( 'D:\image.webp; );

// Save an image to a lossless WebP
ImageEnView1.IO.Params.HDP_Lossless := True;
ImageEnView1.IO.SaveToFileWebP( 'D:\image.webp' );


// WebP Size Comparisons
ImageEnView1.IO.LoadFromFile( 'D:\Alpha.png' );   // Original PNG - 610KB

ImageEnView1.IO.Params.HDP_ImageQuality := 1.0;
ImageEnView1.IO.Params.HDP_Lossless     := False;
ImageEnView1.IO.SaveToFile( 'D:\image100.WebP' );  // 162KB

ImageEnView1.IO.Params.HDP_ImageQuality := 0.9;
ImageEnView1.IO.Params.HDP_Lossless     := False;
ImageEnView1.IO.SaveToFile( 'D:\image90.WebP' );   // 96KB

ImageEnView1.IO.Params.HDP_ImageQuality := 0.7;
ImageEnView1.IO.Params.HDP_Lossless     := False;
ImageEnView1.IO.SaveToFile( 'D:\image70.WebP' );   // 60KB

ImageEnView1.IO.Params.HDP_Lossless     := False;
ImageEnView1.IO.SaveToFile( 'D:\image01.WebP' );   // 37KB

ImageEnView1.IO.Params.HDP_Lossless     := True;
ImageEnView1.IO.SaveToFile( 'D:\imageLossless.WebP' );  // 329KB (Lossless)
