The composite image color changes

[jueqing1015]

I created a new MAGICKIMAGE and composited it on another picture, but its color changed and the color area was yellow
MagickColor Color=MagickColors.White
MagickImage image = new MagickImage(Color, rect.Width, rect.Height);
image.Density = MagickPic.Density;
MagickPic.Composite(image, rect.Left, rect.Top);
MagickPic.Write("c:\jpg.jpg",MagickFormat.Jpeg); ////The image color is normal after saving
PictureBox.Image = MagickPic.ToBitmap();//Converted to BITMAP and displayed in PictureBox The image color is abnormal
NO。1 Original image
NO.2 Images saved locally
NO. 3 Image displayed on PICTUREBOX

I am unable te reproduce your issue. Is it possible to create a super small program that demonstrates the issue and publish it on GitHub?

Thanks for reporting this and providing me with an example. Your code made it clear that I created an incorrect optimization for Grayscale images. I have fixed this and this will be resolved in the next release of Magick.NET. For now you could do image.ColorSpace = ColorSpace.sRGB to resolve your issue.

A new release has just been published that resolves this issue.
