Aspose pdf save greyscale image instead of color one

Aspose.PDF Product Family

Hi,

I used Aspose pdf(dll file version: 17.2.0.0) to save each image in the pdf to file then replace the image in the file with the new saved ones.

Page p;
XImageCollection xImageCollection = p.Resources.Images;
XImage xImage = xImageCollection[index];

xImage.Save(outputImage, ImageFormat.Png);
using (FileStream imgFile = new FileStream(outImgFile, FileMode.Open))
{
p.Resources.Images.Replace(index, imgFile, imgQuality);
}

The expected output image should be processed and have the same look with the input image, however the color changed to greyscale, and the check box is turned into black-filled. Please check my attachments for more details.
