- The Delphi CD-ROM disk includes a set of add-in units in the INFO\EXTRAS directory.
- You will find three subdirectories, FIF, JPEG, and ZLIB. Their contents are as
- follows:
-
- FIF:
- This directory includes the Delphi unit files FIF.pas and FIFDLLs.pas, which
- implement a graphic class (TFIFImage) and its helper object (TFIFData) for
- images compressed using Iterated System's FIF format. TFIFImage provides read-
- only access to FIF files. To create or modify FIF files, you must use Iterated
- System's Fractal Imager.
-
- In order to use the FIF units, your application must use the FIF decoding DLL.
- Run the Fd12w32.exe executable found in the INFO\EXTRAS\FIF directory to install
- the FIF decoding DLL.
-
- JPEG:
- This directory includes the Delphi unit files JConsts.pas and JPeg.pas, which
- were used to generate the .DCU files installed with Delphi. The JPeg unit (and
- the .DCUs installed with Delphi) defines a graphic class (TJPEGImage) and its
- helper object (TJPEGData). The .DCUs installed with Delphi are completely self-
- sufficient -- you do not need any of the files in the INFO\EXTRAS\JPEG directory
- in order to use these. However, if you wish to read or alter the JPEG source,
- you may edit the unit files in the JPEG directory. If you recompile the units in
- the INFO\EXTRAS\JPEG directory, you must link in the object files for the Independent
- JPEG group's (IPG) implementation of the JPEG compression/decompression standard.
- The OBJ files that comprise this JPEG library are included in the OBJ subdirectory.
- If you wish to view the source files for those OBJ files, you can look in the SRC
- directory. The SRC directory also includes a readme file that provides more
- information, including distribution information.
-
-
- ZLIB:
- This directory includes the Delphi ZLIB unit file, which implements utilities
- for compressing or decompressing information using the freely distributable
- library written by Jean-loup Gailly and Mark Adler. This unit provides two
- stream objects, TCompressionStream and TDecompressionStream, that can be used
- to compress information as it is written, or decompress information as it is
- read. It also includes the global CompressBuf and DecompressBuf procedures to
- compress and decompress information using buffers. To use the ZLIB unit, you
- must link the OBJ files in the OBJ directory to your Delphi application. The C
- source for these .OBJ files is included in the SRC directory, along with a
- readme file that provides more information about the library and a disclaimer
- by the authors.
