RgbColorProfile

JpegImage.RgbColorProfile property

Il profilo colore RGB per immagini jpeg CMYK e YCCK. Deve essere abbinato a CMYKColorProfile per una corretta conversione del colore.

public StreamSource RgbColorProfile { get; set; }

Esempi

L’esempio seguente carica PNG e lo salva in CMYK JPEG utilizzando il profilo ICC personalizzato. Quindi carica CMYK JPEG e lo salva di nuovo in PNG. La conversione del colore da RGB a CMYK e da CMYK a RGB viene eseguita utilizzando profili ICC personalizzati.

[C#]

string dir = "c:\\temp\\";

// Carica PNG e salvalo in CMYK JPEG
using (Aspose.Imaging.FileFormats.Png.PngImage image = (Aspose.Imaging.FileFormats.Png.PngImage)Image.Load(dir + "sample.png"))
{
    using (System.IO.Stream rgbProfileStream = System.IO.File.OpenRead(dir + "eciRGB_v2.icc"))
    using (System.IO.Stream cmykProfileStream = System.IO.File.OpenRead(dir + "ISOcoated_v2_FullGamut4.icc"))
    {
        Aspose.Imaging.ImageOptions.JpegOptions saveOptions = new Aspose.Imaging.ImageOptions.JpegOptions();
        saveOptions.ColorType = Aspose.Imaging.FileFormats.Jpeg.JpegCompressionColorMode.Cmyk;

        // Usa profili ICC personalizzati
        saveOptions.RgbColorProfile = new Aspose.Imaging.Sources.StreamSource(rgbProfileStream);
        saveOptions.CmykColorProfile = new Aspose.Imaging.Sources.StreamSource(cmykProfileStream);

        image.Save(dir + "output.cmyk.jpg", saveOptions);
    }
}

// Carica CMYK JPEG e salvalo in PNG
using (Aspose.Imaging.FileFormats.Jpeg.JpegImage image = (Aspose.Imaging.FileFormats.Jpeg.JpegImage)Image.Load(dir + "output.cmyk.jpg"))
{
    using (System.IO.Stream rgbProfileStream = System.IO.File.OpenRead(dir + "eciRGB_v2.icc"))
    using (System.IO.Stream cmykProfileStream = System.IO.File.OpenRead(dir + "ISOcoated_v2_FullGamut4.icc"))
    {
        // Usa profili ICC personalizzati
        image.RgbColorProfile = new Aspose.Imaging.Sources.StreamSource(rgbProfileStream);
        image.CmykColorProfile = new Aspose.Imaging.Sources.StreamSource(cmykProfileStream);

        Aspose.Imaging.ImageOptions.PngOptions saveOptions = new Aspose.Imaging.ImageOptions.PngOptions();
        image.Save(dir + "output.rgb.png", saveOptions);
    }
}
