Hi,

I have to create a simple one-page pdf file with a couple of images and some text.

If I use only black text, as usual, I get a 51Kb pdf file. If I decide to write only one piece of text in blue (leaving the other text in black) the file becomes 65Kb. If I use more colours, no problem, the file remains 65Kb.

Does someone know the reason ?

I'm using QuickPDF DLL 8.13

We would need to see and compare the PDF files to see what is happening and why the file sizes are different.

Using the following code I generated two files - 3.28KB and 3.33KB.

QP.NewDocument();

QP.SetOrigin(1);

QP.DrawText(20, 20, "Black Text");

QP.SaveToFile("out.pdf");

QP.NewDocument();

QP.SetOrigin(1);

QP.DrawText(20, 20, "Black Text");

QP.SetTextColor(0, 0, 1);

QP.DrawText(20, 50, "Blue Text");

QP.SaveToFile("out1.pdf");

You must be doing something else. Are you sure you are re-using an existing font and not adding a whole new font ?

Andrew.

You are right; I have to subset fonts because I need small size pdf files, and there was a mistake in my susbet procedure when I used colours, so I was adding extra-fonts.

Thank you
