Max font size printing to any screen size.

[Pete]

This was just for fun, in response to another forum member looking for a way to wrap a long string around a screen so it nearly fills up the entire screen. In other words, if it is very long, it is printed in a smaller font. Small, it gets printed in a larger font.

It isn't totally goof-proof, so I'm happy to take any comments as to improvements. This isn't my typical SCREEN 0 stuff, but it's close. It uses _NEWIMAGE.

Code: (Select All)

'handle& = _NEWIMAGE(800, 600, 256)
'SCREEN handle&

handle& = _NEWIMAGE(_DESKTOPWIDTH, _DESKTOPHEIGHT, 256)
SCREEN handle&
_SCREENMOVE 0, 0
_DELAY .1
sw = _WIDTH
sh = _HEIGHT

x$ = "Fourscore and seven years ago our fathers brought forth, on this continent, a new nation, conceived in liberty, and dedicated to the proposition that all men are created equal. Now we are engaged in a great civil war, testing whether that nation, or any nation so conceived, and so dedicated, can long endure. We are met on a great battle-field of that war. We have come to dedicate a portion of that field, as a final resting-place for those who here gave their lives, that that nation might live."

Ahhhh yes. _FONTWIDTH and _FONTHEIGHT. I was completely unaware of these, but not for lack of looking through the docs. I guess I simply missed these.

That should be the missing link that will allow me to do what I want.

Thank!
