Determine the color of a coordinate in a PDF

I'm using the Syncfusion File Formats library in a console application referencing .NET Framework 4.7.2 to create PDFs based on values passed to the program.

So far everything works properly, but was wondering if given a location on the page (x,y) is there a way to return what color is at that location.  I'm wanting to draw a line up to the point a color matching a color used in an image is found.

Hi Brian, 
Greetings from Syncfusion. 
Yes you can achieve this requirement by following the below steps. 
  1. Convert PDF to Image using the below code snippet.
// Load PDF document 
PdfLoadedDocument ldDoc = new PdfLoadedDocument("input.pdf"); 
// Convert first page to image 
Bitmap page0 = ldDoc.ExportAsImage(0); 
  1. Get the color from the image using the GetPixel method.
