ever wanted to use image components in your program
only to find that you had to add the popup menu's & file dialog's
which should have been part of the component ?
I wrote TImagePlus & TDBimagePlus so I can forget all that coding and get
on with the programming
to use these components you simply install them on your component palette
and use them as you would tImage or tDbImage
the new properties are as follows
Aspect (TImagePlus) like stretch except maintains aspect ratio
OpenDialog, SaveDialog (Delphi 2)
OpenPictureDialog, SavePictureDialog (Delphi 3,4,5)
allows you to specify your own open & save dialogs
if you do not specify any dialogs they are created as needed
Note: assigning a popup menu defeats the built-in menu
if you want to extend the menu then you can access the MENU variable of the
TImagePlus or TDbImagePlus components
who am I ?

History
1996 first version - Unreleased basic cut & paste functions
1997 rewrite of code and changed the base class due to problems
implementing the aspect ratio function, also added dialogs for open/save
1999 rewrite (again) to make it work with Delphi versions 1-4
also added Twain support using eztwain.dll
2000 First Public Release
Re-wrote the twain loading code to load the dll dynamically instead of static
Things to do
Recent file list ??
I am currently working on a set of Language neutral components for Delphi
which support Unicode and dynamic language support using standardized
dll files to provide automated translation of messages, captions, hints etc
when this is ready (currently only working on Delphi 2 due to bugs)
I will change these components to support full NLS capability
Also in the pipe-line is an image filter component which makes use of
the registry to update graphic format support without recompiling
your application
This version supports Delphi 1 - 4 and C++ Builder (tested with version 1)
to use it is easy, Install it and use it as you would TImage
there is no coding work needed, just right click on the TImagePlus/TDbImagePlus object and use the menu
you can set the options for the built-in dialogs through the DialogOptions property, they are the same options you have for TOpenDialog/TSaveDialog
Want Twain? easy use TImageTwain/TDbImageTwain, Compile, Right click, Select Source, Click Acquire
Known limitations
the Delphi 1 (16 bit) code uses static linking so if EZTWAIN.DLL is not in your path your application fails
OnScanError event not implemented although the property exists
Requirements
486 or better
8 MB ram for 16 bit Delphi 1 version
16 MB ram Win 95/98 NT
Installed twain drivers for twain functions.
