Can anyone help me figure out why the drawing text on a PDF (Left) looks different than drawing to a canvas using RenderPageToDC (Right).

This is the same information - the page on the right, if saved to a PDF (using SaveToFile) would open in acrobat reader looking like the page on the left.

So, I'll post all the sample code you want, there's just a lot of code behind it and I don't know where to start.

Andrew,
I see the images just fine in the latest version of Firefox. Maybe its your browser's settings.

So does anyone know if it's a known issue regarding SetTextScaling not looking the same on the Delphi canvas vs. a PDF? That's pretty much the biggest gripe I've got with QuickPDF right now.

I believe this has been fixed in the 8.15 Betas.

QP.SetTextSize(72);

QP.DrawText(100, 100, "Hello World");

QP.SetTextScaling(95);

QP.SetTextWordSpacing(-1);

QP.DrawText(100, 200, "Hello World");

QP.SaveToFile("out.pdf");

If I call RenderPageToDC then the strings are of a different length which is expected and the output now matches the RenderPageToFile output.

Andrew.
