I noticed an issue when changing color of text within link rectangle using AsposePDF v23.12.0.0
Please see attached “input.pdf” and “output.pdf”.

input.pdf : Before changing color of text within link rectangle
output.pdf: After changing color of text using AsposePDF.net v23.12.0.0

Description : Created a link with text color blue by selecting the rectangle exactly the text area of “10 DATA QUALITY ASSURANCE” in the input.pdf document. But if you observed that output.pdf document, the link created with diffirent places not exactly what we selected the coordinates that covers the text “10 DATA QUALITY ASSURANCE”.

Aspose.Pdf.Page page = pdf.Pages[Int32.Parse(data.linkInfo[i].sourcepage)];

double llx = double.Parse(data.linkInfo[i].llx);
double lly = page.MediaBox.Height - double.Parse(data.linkInfo[i].lly) - double.Parse(data.linkInfo[i].height);
double urx = llx + double.Parse(data.linkInfo[i].width);
double ury = lly + double.Parse(data.linkInfo[i].height);
Aspose.Pdf.Rectangle AnnotRect = new Aspose.Pdf.Rectangle(llx, lly, urx, ury);

LinkAnnotation link = new LinkAnnotation(page, AnnotRect);

double pageHeight = destpage.MediaBox.Height;
XYZExplicitDestination mag = new XYZExplicitDestination( pdf.Pages[Int32.Parse(1)], 0, pageHeight, 0);
link.Action = new GoToAction(mag);
page.Annotations.Add(link);

// Apply Link Text color
foreach (Annotation annotation in page.Annotations)
{
    if (annotation is LinkAnnotation)
    {
        Aspose.Pdf.Rectangle rect = annotation.Rect;
        if (rect.LLX == AnnotRect.LLX && rect.LLY == AnnotRect.LLY && rect.URX == AnnotRect.URX && rect.URY == AnnotRect.URY)
        {
            TextFragmentAbsorber absorber = new TextFragmentAbsorber();
            absorber.TextSearchOptions.Rectangle = rect;
            Rotation pageRotation = page.Rotate;
            page.Rotate = Rotation.None;
            page.Accept(absorber);
            foreach (TextFragment textFragment in absorber.TextFragments)
            {
                try
                {
                    if (data.linkInfo[i].textcolor == null)
                    {
                        System.Drawing.Color color1 = System.Drawing.ColorTranslator.FromHtml(textFragment.TextState.ForegroundColor.ToString());
                        textFragment.TextState.ForegroundColor = Aspose.Pdf.Color.FromRgb(color1);
                    }
                    else
                    {
                        System.Drawing.Color color1 = System.Drawing.ColorTranslator.FromHtml(data.linkInfo[i].textcolor);
                        textFragment.TextState.ForegroundColor = Aspose.Pdf.Color.FromRgb(color1);
                    }
                }
                catch(NullReferenceException)
                { }
            }
            page.Rotate = pageRotation;
        }
    }
}
pdf.IsLinearized = true;
pdf.Save("output.pdf");
pdf.Dispose();
