New Post: Density not affecting font size

I am wondering if anyone else has run into this. From what I understand when you set the image density and the font size renders in relation to this (points)

I am creating an online preview of a business card. The preview is supposed to be 171 PPI and am setting the DrawablePointSize to "10".

The image is getting saved at 171 PPI which I want but the font is rendering in size as if the low res preview was 72 PPI. Here is the caption function I am using for each text field:

public void WriteCaption(MagickImage Background, string Txt, double PPI, string fontFamily, double fontSize, string FontColor, int CaptionX, int CaptionY, int CaptionW, int CaptionH, string TextAlign)
    {
     
        if (!String.IsNullOrEmpty(Txt))
        {
            var bgColor = new MagickColor(Color.Transparent);
            var fillColor = new MagickColor("#000000");

            if (!String.IsNullOrEmpty(FontColor))
            {
                fillColor = new MagickColor(FontColor.Replace("0x", "#"));
            }
            Background.Density = new PointD(PPI, PPI);

            using (MagickImage Caption = new MagickImage(bgColor, CaptionW, CaptionH))
            {
                Caption.Density = new PointD(PPI, PPI);
                Caption.Format = MagickFormat.Png;
                Caption.HasAlpha = true;
                Caption.VirtualPixelMethod = VirtualPixelMethod.Transparent;

                var gravity = new DrawableGravity(Gravity.West);

                if (TextAlign.ToLower() == "center")
                {
                    gravity = new DrawableGravity(Gravity.Center);
                }
                if (TextAlign.ToLower() == "right")
                {
                    gravity = new DrawableGravity(Gravity.East);
                }
               
                DrawableTextAntialias txtDrawableTextAntialias = new DrawableTextAntialias(true);
                DrawableText txtDrawableText = new DrawableText(0, 0, Txt + " " + fontSize);
                DrawablePointSize txtDrawablePointSize = new DrawablePointSize(fontSize);
                DrawableFont txtDrawableFont = new DrawableFont(fontFamily);
                DrawableFillColor txtDrawableFillColor = new DrawableFillColor(fillColor);

                Caption.Draw(txtDrawableTextAntialias, txtDrawableText, txtDrawablePointSize, txtDrawableFont, txtDrawableFillColor,gravity);
                Background.Composite(Caption,CaptionX, CaptionY, CompositeOperator.Over);

               
            }
        }
