What's new in version 5.0 (released Feb 20, 2004)
- Important note!
Although several versions of gd, freetype, libpng, zlib libraries have been
released recently, we did not update the version of our component. Our
component is for Windows platform unlike gd libraries.
That is why we changed several parts in the source code of gd to prevent
memory leak problems and crashing of the component.
Although many of our ideas have been implemented in latest versions of the
library, our code still differs. That's because we included these files in
the final distribution.
- Used the latest versions of libraries
GD - http://www.boutell.com/gd/
FREETYPE - http://www.freetype.org
LIBPNG - http://www.libpng.org
ZLIB - http://www.zlib.org
JPEG LIB - ftp://ftp.simtel.net/pub/simtelnet/msdos/graphics/jpegsr6.zip
-
We also added a new version of the component called Active Image Lite.
This version is intended for users who need only the component itself without
source code. Thus you get the opportunity to use all functions of the
component for a lower price. If you need to change Active Image license,
please contact our support department.

Quick start instruction to use ActiveImage
component
- Register ActiveImage component on your computer
(it's not necessary to have a web server). Open Start->Run
dialog and type "path_to_regsvr\regsvr32.exe
path_to_activeimage\ActiveImage.dll". Make sure you specify correct
paths. For example, "C:\windows\regsvr32.exe
C:\ActiveImage\ActiveImage.dll". You should see "ActiveImage DLL
registered successfully" message.
- Run block.vbs smaple located in samples folder. You
can verify that newly created image has appeared (the file
with the image named block.png will be created in "AI" folder of
drive C).
- Sample 3 "Copying image" needs file
"C:\AI\rose.jpg".
- Sample 2 "Writing image to database". Create DSN
"tonec" that will point to MS Access "tonec.mdb".

Quick start instruction for ASP
developers
- Create a web-site or virtual directory
- Register ActiveImage component on your computer
(it's necessary to have a Web server like IIS or PWS). Go to menu
"Start", choose "Command Prompt" and change the directory to where
ActiveImage component is located. Run from command line "regsvr32
ActiveImage.dll". You should see "ActiveImage DLL registered
successfully" message.
- If you have problem with registration, try to
specify path before regsvr32.exe and ActiveImage component. For
example, "C:\windows\regsvr32.exe
C:\ActiveImage\ActiveImage.dll"
- Place "diagram.asp" from distribution package to
your virtual directory.
- Open corresponding url from your browser.

Sample 1. Drawing pie charts and text lines of
different fonts.
Diagram.vbs
Dim im
dim dat1,r1,g1,b1
Set im = CreateObject("ActiveImage.Images.1")
im.CreateImage 300,300
im.SetColor 0,255,0
im.Fill 299,299
dat = "20,45,15,9,11"

g = "0 ,0,255,255 ,0"
b = "0 ,255,127,255,255"
dat1 = split(dat,",")
r1 = split(r,",")
g1 = split(g,",")
b1 = split(b,",")
x = 0
For i = 0 to 4
im.SetColor r1(i),g1(i),b1(i)
im.DrawFilledArc 150,150,160,160,(x*3.6),(dat1(i)+x)*3.6
x = x + dat1(i)
next
im.SetFont 4
im.SetColor 0,0,0
im.DrawText 20,20 , "HTTP://WWW.TONEC.COM/"

from file, find canvas dimensions, copy the part of image with
linear transformations and save to Jpeg file with lowest
quality.

Dim im, rs
Set im = CreateObject("ActiveImage.Images.1")
im.SetImageType 1
im.ReadFromFile "C:\AI\rose.jpg"
h = im.GetHeight
w = im.GetWidth

Source code compilation instructions (not needed
for most users)
If you want to build the component from the source code:
- Install all required libraries
ZLIB
LIBPNG
FreeType
JPEG LIB
GD LIB
- Change the following line in stdaxf.h
// Include ADO Interface/Class Descriptions
(ADO 1.5 Version) #import "c:\Program Files\Common
Files\System\ado\msado15.dll" no_namespace rename( "EOF", "adoEOF"
)
if "msado15.dll" is located in different
directory.
- Build project
- Sample 3 "Copying image" needs file
"C:\AI\rose.jpg".
- Sample 2 "Writing image to database". Create DSN
"tonec" that will point to MS Access "tonec.mdb".
