Glad that I could be of help.
To change the text height use picturebox.font.size = 14 'text size in points.
You can also change the font with picturebox.font.name = "font name". You will want to be careful about changing the font though, because it is possible that not everyone will have the font you want to use. If the specified font is missing the system will substitute, but the substitute may not be desirable.
As for the justification options (I hope I'm wrong but...) I think you'll have to take care of those yourself in code. I do know that there are functions that will return the length of the text string (actual physical length, not number of characters) taking into account the font size and character spacing. I don't remember the names of these functions offhand but when you find them you can use them to determine where to place currentx and currenty to get the desired justification.
