David 7 April 2006
|
||||
- extended upper_case so that it draws graphics
|
||||
(text, image, bouncing ball)
|
||||
NOTE: to get this to work, you have to put in your build dir:
|
||||
- file called "logo.jpg" (the image)
|
||||
- Helvetica.txf
|
||||
- a file called "in" (any old text)
|
||||
- added text functions to library
|
||||
|
||||
uppercase/
|
||||
upper_case.C
|
||||
win_build/
|
||||
libboincapi.vcproj
