This is a function that can be included to your program to easily allow the user to take a screenshot of the screen or active window, or open an existing image, it can then write some text to the image, defining the size, style, font, colour and positioning and then save it in any format to another location, or overwrite the existing file. Many thanks to PhiLho, Lexikos and Sean.
An Example file is included, and the functions usage is:
Code:
TextToImage(In, Text, Output, XPos, YPos, Size, Align, Weight, Font, TColour, Style)

This is another good demonstration of what can be achieved using gdi+.
as I do website design, and get frustrated with IE6 and having to use js to show transparencies on my pngs, and then cant load then from css with this method. very annoying.
