Ha ~ ~ long time did not send the article a
donkey - long ago changed jobs recently also good, relatively empty -
not long-winded, speaking at today's topic -
Because of their work, recently needed to use ASP, ASP.NET pictures verification (and can not use the component)
ASP.NET System.Drawing itself can be used directly to turn into a font drawing, draw miscellaneous point, using a gradient .. . etc. is not a problem
but the blanket ~ ~ ASP .... can be difficult to find examples of most of the network, to the bottom of this it ~

Fixed font size is fixed .... .... .... can only be set miscellaneous points
that - because the system did not have a choice, that is, ASP, but to add this functionality -
Well, then ... to get a donkey , to borrow vb.net to generate font string (vNumberData), into the picture inside the array
and then modify the ASP program - now .... there gradient, foreground Noise, miscellaneous line background, font edges soften, you can choose they want ..... even use the font in the text -
this is a graphic produced 
ha ~
this ~ it is used to generate vNumberData program screen - 
the program of the last donkey attach produce vNumberData, asp pages on the web page there are instructions to modify the ~
