(About the author) |
| | | I wanted to do something with special FX, like real dropshadow FX like in Photoshop or PaintShopPro.
Nobody could answer my questions at www.vbforums.com, only "Cyborg" gave me some usefuladvice about the blending parts. (tx...)
Now, the GFX part has already been coded and works fine & fast. Very fast! Very very fast!!!
SIMPLE CODE!!! NO DIRECTX!!! TRANSPARENCY!!! TRANSLUCENCY!!!
This is a preliminary project with goals to maintain a company's ICT infrastructure.
It also includes: hover buttons with special FX (in software, very fast!), SysTray handling, irregular forms, texturing, ...
SMALL CODE!!!

Hi Mad Compie, thats really impressive!
Look for this for a long time!!! Thx
for sharing and 5 from me - LiTe

Just had a closer look (thx for well
commenting!). Folks: No OCX, no GDI+!
Just pure VB! Its fast and there is
potential to speedup the loops. I like
it! LiTe

I don't think
so

Hm, Aki: it is fast!
I.e. I measured
the ticks for a transparent addition of
an image into another image: it's
remarkably faster than Win98's
TransparentBlt() and other TransBlt
routines using BitBlt. Only for very
large transparent images it will be a
bit slower.
Tx for voting guys!

This is a fact, because the algorithms
are performed with arrays of values and
memory copying, not with pixel
routines!

sections, please go to

Hmmm, imho some repeated calcs can be
put out of the loops. Using ElseIf and
other "speed tricks" can speedup
things, too. We will see ... ;) LiTe

I don't know what is for you fast but
to display a sentences "Just a test" &
"ICT builder" on my "slow" P3 650 with
256 Mb RAM took 1.2 seconds and the
best result was 1 sec with 100% use of
my CPU.
Just imagine testing it with
more letters.

Hum, Aki, you'll have to compile it
into a .exe to see the HUGE
difference!
Example:
Display a
larger text (Tahoma, 48):
T =
GetTickCount
DrawDSText Me.hDC,
"This is a larger text", 30, 240,
vbBlack, vbBlack, FXDS_ShadowDepth9,
"Tahoma", 48, True
MsgBox "" &
GetTickCount - T &
"ms"
Results:
Tested on a
PentiumIII@450MHz/128RAM:
If not
compiled, it will be executed @9524ms
(this is almost 10seconds!)
When
compiled, it only takes 330ms!!!
I.e.
almost 29 times faster!!!
T =
GetTickCount
DrawDSText Me.hDC,
"This is a larger text", 30, 240,
vbBlack, vbBlack, FXDS_ShadowDepth9,
"Tahoma", 48, True
MsgBox "" &
GetTickCount - T & "ms"

When compiled its fast, as you
mentioned.
