ImageEn includes a Color Management System (CMS) which enables the rendering of an image with its original colors.



To enable the CMS use:

IEGlobalSettings().EnableCMS := True;

To use LCMS instead of Windows CMS, set the following define within ie.inc and then recompile your packages.

{$define IEIncludeCMS}

When the CMS is enabled loading of images with a color profile will be slower.

If you don't define IEIncludeCMS in ie.inc then only the Windows CMS will be used. Note that Windows CMS is quicker than LCMS.

Examples

// Apply color profile on rendering
IEGlobalSettings().ApplyColorProfileOnRendering := True;  // not actually necessary, this is the default
ImageEnView1.IO.NativePixelFormat := True;  // This means "Do not convert to RGB"
ImageEnView1.IO.LoadFromFile('cmyk-jpeg.jpg');

// Apply color profile before rendering
IEGlobalSettings().EnableCMS := True;
IEGlobalSettings().ApplyColorProfileOnRendering := False;
ImageEnView1.IO.NativePixelFormat := False; // This means "Convert to RGB"
ImageEnView1.IO.LoadFromFile('cmyk-jpeg.jpg');

// Do not apply color profile
IEGlobalSettings().EnableCMS := False;
IEGlobalSettings().ApplyColorProfileOnRendering := False;
ImageEnView1.IO.NativePixelFormat := False; // This means "Convert to RGB"
ImageEnView1.IO.LoadFromFile('cmyk-jpeg.jpg');

// Load a TIFF containing a CMYK profile, save to JPEG maintaining the profile
IEGlobalSettings().EnableCMS := False;
ImageEnView.IO.LoadFromFile('D:\Img with ICC Profile.tif');
ImageEnView1.IO.Params.JPEG_ColorSpace := ioJPEG_CMYK;
ImageEnView1.IO.SaveToFile('D:\Img with ICC Profile.jpeg');

// Load image and apply a color profile
ImageEnView1.IO.Params.DefaultICCProfile.LoadFromFile('C:\Windows\System32\spool\drivers\color\AdobeRGB1998.icc');
ImageEnView1.IO.LoadFromFile('C:\input.tif');

// Save a JPEG with the ICC profile, sRGB2014.icc
ImageEnView1.IO.LoadFromFile( 'D:\201849018_A1.jpg' );
ImageEnView1.IO.params.InputICCProfile.LoadFromFile('D:\sRGB2014.icc');
ImageEnView1.IO.SaveToFile( 'D:\Test_SRGB.jpg' );
