Thank you!
=========
Thank you for purchasing the source to NativeJpg. Your support is appreciated.
About NativeJpg
===============
This is a small-footprint native Object Pascal (Delphi) implementation
to read and write Jpeg files. It provides a fully object-oriented approach
to working with Jpeg files, with clearly defined properties, events and methods.
You can use this code to read and write Jpeg documents from/to files or streams,
generate bitmaps from the compressed data and vice versa. It also provides for
methods to access the meta data in the files, and methods to manipulate the Jpeg
file in a lossless way (rotation/flipping, etc).
Author: Nils Haeck M.Sc. (SimDesign B.V.)
Installation
============
Simply run the installer. It will copy the files to your harddisk in a location
you specify. No actual programs are installed or registered.
You can uninstall all files by clicking UNINS000.EXE in the root or through
Start > Control panel > Add/Remove software > NativeJpg [Remove]
If you want to use NativeJpg in your project, just include the \Source folder
in your project's Search path (see project options).
If you want to use NativeXml in all your projects, you can also add the
\Source folder to your library path.
Compatibility
=============
The full source version is compatible with all flavours Delphi5 through
Delphi2007 (so also the personal).
Help
====
You can use the included NativeJpg.chm help file, and the example to get
started.
Example
=======
The \Demo\Test folder contains an example demo, which shows how to load,
save and manipulate Jpeg files.
