(About the author) |
| | | If you want to adjust the brightness of a picture, rotate a picture with ANTI-ALIASING or AlphaBlend pictures together, maybe using an invisible mask color, and all that in vb and in just milliseconds... then you need this code! I wrote all the calculations in a C++ DLL, because it is much faster and easier to use, you just need a few lines of code to make incredible effects! in the zip-file there is the DLL and a VB-Demo to demonstrate the possibilities and the performance of my dll.<br>
<br>
NOTE: Version 3.0 is released, go to http://www.planet-source-code.com/vb/scripts/showcode.asp?txtCodeId=21470<br>
<br>
UPDATED! 2.0: The new package now also includes a VB-Only-Version with the functions from the dll rewritten for VB, so you can use the stuff without the dll! (though the dll is faster than the still fast VB-code, so i would use the dll). I also included a BUMP MAPPING routine a BLUR filter and an IMPROVED ALPHA BLENDING routine.<br>
<br>
UPDATED! 2.1: Fixed a problem with 16 bit color depth. included MOSAIC filter.<br>
<br>
UPDATED! 2.2: Added some nice, useful timer- and counter-functions. See demo for description. I Also added a complete DOCUMENTATION of all functions with descriptions of all parameters to help you using my code (see "readme.txt").
<br>
<br>Test it and *please* vote for this really useful and good piece of code!<br>
<br>

Hi,
I just wanted to explain why the
main code is written in C++:
The Code
doesn't use SetPixel or GetPixel, but
it still uses many loops and
calculations, ant it would simply be to
slow in VB (BUT: I tried the code in
pure-VB and it is still much faster
than all comparable codes posted here,
less then 100ms for processing a
320x240 picture!!!).
If you want the
code of the dll or a VB-Version of the
routines, just let me know.

Hi Florian. I think i don't have to
explain why i voted excellent for you.
I'd like nevertheless to ask you a
favor and make some suggestions: I have
made some filters in VB and are really
slow (eg. Blur,Noise,Contrast etc... ).
I want to make them in VC++ and
assembly. I know programming these for
the last 3 years-not much because i am
a Database programmer in VB mainly. I
think your rotate and alpha filters are
extremely greatfull but brightness may
need some work (I don't know exactly,
this is just a suggestion). But, as you
said, if you don't mind could you
upload or send me an email of how you
make in C++ these best rotation filter
and alphablend? And a last big favor
and sorry for the large comment. (But
ok, you are the best in grafix in PSC).
May, if you have time of course, you
show me in C++ how to make a quick DLL
mosaic filter? Because VB grafix are so
slow even with API.
|
2/17/2001 9:17:09 PM:The Author
Ho, thanks for the praises!
First of
all, all suggestions are welcome. If
you have any effects/filters (like a
good brightness control, contrast, blur
etc.) feel free to send me the code,
and i will update the dll.
my email
address is webmaster@flomix.de.

Yo, great code. I really like the
anti-aliasing thingy. Here's a site
where you can find some great gfx stuff
done in vb like HUE, blur and much
more.
www.vbaccelerator.com - look in
vbMedia.
|
2/18/2001 5:14:54 AM:Night Wolf
Oh yeah can you email me the code in
vb. Thanks.
|
2/18/2001 5:50:17 AM:Stephan Kirchmaier
Pls. email me the code in VB too.
|
2/18/2001 6:28:48 AM:gain@westerncanada.com
I too would appreciate this in VB code.
Excellent work !!
|
2/18/2001 9:23:28 AM:farouk
Excellent work..keep it up
if you
could send me the code in vb
and c++ I
would be grateful
|
2/18/2001 10:39:46 AM:Kostas D.
Hi again. Thanks again for your offer
to construct my VB filters in C++ but
finally i manage to compile myself a
non-MFC Win32 DLL using SetP, GetP and
LineTo (i had made DLLs for DB Apps
previously) which works fast and fine.
I also found some good mosaic codes in
PSC and Vbaccelerator.com (Thankz to
Night Wolf too). I will upload my work
with full source code soon. Continue
your great coding...

Florian,
Great work, and I
appreciate your willingness to share
it. Can you please send me the code in
C++ and VB. Thanks!
|
2/18/2001 12:20:43 PM:Florian Egel
Hey, big thanks to all for the good
feedback! Due to the requests i updated
the Code: it now contains some new
functions (better AlphaBlending, Blur
filter, BumpMapping), and a
VB-Only-version of the routines. I hope
this helps.
|
2/18/2001 3:14:00 PM:Ray Hildenbrand
Hello, great post. i did notice one
thing you might be able to help me
with, the alpha blend function ( as
well as the bump) just show a black box
in this version, but the original
posting worked correctly on my system.
any ideas? BTW my layer manager control
i am developing would really go hand in
hand with this code. five globes eh

2/19/2001 7:33:37 AM:Florian Egel
It was my mistake, I solved the black
box problem whith AlphaBlending and
BumpMapping (the previous code just
worked with 32 bit color depth, now it
also supports 16 bit).
|
2/19/2001 8:21:37 AM:Jeffrey A. Miller
Hello,
Very nice code, extremly
fast. Could you please forward me the
DLL code in C++ & VB.
Thanks

Hi Florian Egel !
I've got some
questions about your code. Could you
please write your e-mail adress for
contact!?
Thanks
|
2/19/2001 7:55:46 PM:Florian Egel
sure, my email address
is
webmaster@flomix.de.
Ask whatever
you want, i would like to help
whereever i can. And if you have
remarks or suggestions feel free to let
me know, too!
|
2/19/2001 8:29:49 PM:Florian Egel
I just added a pretty cool Demo and a
complete Documentation of all functions
with descriptions of all parameters to
the package, check it out if you like!
|
2/22/2001 8:25:52 AM:J. Owen
Wow, this code is AWESOME! I often
tried to make such effects, but i never
got fast results and all other samples
about this are terribly slow, too, but
your great code runs real-time even on
my comp... Congratulations and thanks a
Lot!
5 Globes, you are really worth it.
|
2/23/2001 8:34:46 AM:Mark Robert Strange
Absolutely Exsquisite. I am very
interested in the C++ DLL source code,
I would appreciate it if you could
email it to me (IMNoPatzer@excite.com).
Many thanks, 5 Globes all the way.
|
2/26/2001 9:06:18 AM:Guido van Laar
Thanks for sharing your great code, I
rated you 5 globes.
If possible, I
would like to receive a copy of the C++
dll source code (GvL@Pobox.com).

Excellent! Really 'MustHave'. Simplest
VB coding in aggregate with fastest C
or ASM libraries makes a splendid apps.
Keep a good work, Florian! My vote is
'Excellent'.

Man, everyone gets excited to see
samples. There is no code for the
actual work! its in a DLL! and it won a
contest? god people, keep the planet
clean!
Sorry for this, but I just
think to win a contest, you should post
code not samples around a component and
release the sample only. I gave it poor
rating till code is posted
|
3/14/2001 7:43:12 PM:Florian Egel
If you would have looked at the code,
you would have seen that there is a
VB-only-version with full source...
sorry, but your statement is just wrong.
|
3/14/2001 11:07:20 PM:fadi
My mistake, I missed the VB version only

3/15/2001 11:35:34 PM:Roger the Camel
Hey Florian Egel, from what I have read
in all this feedback ur the man to see
about graphic effects... well Im
currently in the process of making a
game, 2D RPG, kinda like zelda on snes
but with better looking graphics. Well
anyway, i want to put some graphic
effects in that will add to the
atmosphere of the game and i was
wondering if ud like to work with me,
even if its as an advisory role or
something, anyway, my e-mail is
grant73@ihug.co.nz, contact me if you
would like.

Hi Florian, I'm only sorry that my
limited knowledge of English is not
enough to express my appreciation (and
I had only saw version 2.2...non I'm
going to look for version 3.2).
If I
do not bother you, I would have a
question (hope not too silly): which is
the difference (in coding) between
Brightness and Saturation control ? I
wanted to implement them (in VB6) , but
in my mind the approach seems the
same.
Thanks anyway
Giacomo

Hi there,
This is Pritesh Sheth from
India,
First of all, your code is
GREAT!!.
I am a programmer, developing
small application, and would like to
use you .dll, can i use it ? and it
will be so nice of you if u could send
me the c++ code so that i can learn how
things are done.
hey, one thing it
crashes or leacking memory while
dealing with big size bitmaps
(1024*768) specially alphablend.
|
6/19/2001 10:00:32 AM:Florian Egel
I got many mails complaining that the
dll does not work properly with big
pictures like 1024x768, but it was not
designed to. I focused on
realtime-speed with smaller pictures,
not on compatibility with large
pictures. If I would not be so busy, I
would perhaps write another DLL to do
these tasks... ;-)

ooooo can i have the dll too?
|
10/15/2001 5:21:21 PM:Florian Egel
MESSAGE TO ALL:
I know, I ignored
your requests for the source code for
the last months and I am very sorry
about it, but I was really busy and got
almost no time to go online.
I
apologize to all of you and uploaded
the sources to my homepage. You can
find them
under

oxcbmp_src.zip

hey, i would love for you to send me
the source for the dll file. i hate
that vb cant do rendering that fast
|
9/18/2002 9:35:05 AM:
A little speed-up for the main sum in
the alphablending routine that may be
worthy of discussion from the DLL
source, FoxCBmp.cpp
ShadeColors(...):
default :
return
((((Src&0x0000FF)*(~Shade))>>8)+(((Dst&0
x0000FF)*Shade)>>8))&0x0000FF
|((((Src&0x00FF00)*(~Shade))>>8)+(((Dst&
0x00FF00)*Shade)>>8))&0x00FF00
|((((Src&0xFF0000)*(~Shade))>>8)+(((Dst&
0xFF0000)*Shade)>>8))&0xFF0000;
|
9/27/2002 9:29:48 AM:
VERY VERY VERY GOOD.
|
11/8/2002 11:35:27 AM:
Excellent work.
if you
could send
me the code in vb
and c++ I
would be
grateful
I have 2 version of the DLL
but not completed
thanks
