This is an example of the code I use.
I know that the problem is in pixel method, that transform Image, that
becomes almost a bitmap, but I need to fix Font in Canvas, because
anothe Font can make unwanted effects when I combine lines, String and
another graphics elements. Now, I think that default pdf Font (the one
of first String) is Helvetica, while default of Canvas is named Dialog.
Moreover, default java.awt.Font for paint appears different in Windows
and Linux. As com.lowagie.text use some font saved in
com/lowagie/text/pdf/fonts, can I use this Fonts (that are the same in
all PC) for Frame?
I need something as "public java.awt.Font getDefaultPdfFont()" for
insert a g.setFont in paint method of Canvas. It exists?
Thank you.
