Re: fast drawing in delphi

Dear Bjørge,
please tell me what exactly u was trying to do.
I cannot understand almost nothing from your message
except it was 10% slower... slower than what?
What is your "fast paint" all about?

Hey guys, until now the best solution seems to
be FastLib. Thanks Paul!

Arosh Partow's Graphics32... I am testing your library now... Thanks!

Marteen, please excuse the over-excited Arosh's tone about Graphics32.
I am sure he doesn't mean to bother other people here and he is just being
highly optimistic about the speed of the Graphics32 and fastGEO libraries...

Hey guys, finally I decided to write a short app for testing all of the
"FASTEST"
2D graphics solutions for Delphi to draw the 100x100 hexagons!

Until now we have several candidates:
1) Gordy's FastLib
2) Arosh's Graphics32
3) M$ DirectDraw
4) Scanline method (go figure out how to draw 100x100 hexagons)
5) WinAPI drawing functions --> Offscreen bitmap drawing --> BitBlt () for
screen output

Time resolution will be milliseconds

I dedicated web site can be a good place to see the results of the graphic
speed test.

Peace and Merry Christmas!

Ronald
